FOR CR 500 ADVICE GO TO KEN KAPLAN MOTORCYCLE OF AMERICA HE HAS A YOUTU E THAT DUDE KNOWS EVERYTHING ABOUT BIKES DIRT BIKES AND MOTORCYCLES PERIOD HES THE GUY TP GO TO HE SELL THE BEST CR 500S IN THE NATION
Hi. You might heard this already, if you are low on compression the enginge will run rich. So it might be a good idea to check the piston and ring... And also, a reed valve engine should never spit back the fuel thru the carb so i’m guessing it’s time to rebuild the reed valve... Keep up the good work, boys! 👍
They said it was nearing 150psi which is within spec. I wonder if the reeds themselves are bad. The reeds seem to get over looked quite often because they don't wear out as quickly as everything else. Even if they don't have corners chipped off they might be hanging open enough to suck air. :)
I remember when 500s were sometimes cheaper than 250’s because how many people would pick them up and then ride it once, scare the s**t out of themselves and then immediately want to unload it cheap. It’s crazy what they sell for now. I also love how you guys went straight from a kx65 to a cr500.
they're barely faster then a 250 , for 2x the cc they only gain around 8hp and 13kg more mass , throwing a small amount of cash at a 250's engine gets you a better power to weight ratio + more nimble bike.
@@TheCraigy83is that for a stock comparison or true built race bikes? Had my fair share of rides on different bikes, I had a 2017 kx250 rt build and could pull ahead of most stock 250s even the most modern ones, kx500 left me like i was sitting still and I had her full beans
Ik I got lucky getting that bike but had to sell it because I needed a car hopefully they didn’t pay the price the guy I sold it too posted it for lmao
The exhaust leak is still there and will effect how it’s running. The pipe gets a donut and the flange attached to the motor gets a metal gasket as well.
The Big CRs were always hard work, they always oiled up if you didn't have a big space to open them up, also if I remember correctly the transmission case oil also lubricates the wet clutch so they can get messy, oh yes you might want to replace the flywheel as the magnets weaken with age/heat .. and don't be surprised if it wants new rings/piston & a rebore every few hours of use ..... for all those negatives just a few moments hitting the power band are worth all the hassle. I did notice what looked like some ridging in the clutch basket, if it's not too deep sometimes a light file can help remove them and stop clutch stick/judder. One other thing you might want to check and or replace are the reed valves, they do get lazy and stick open making for hard starting and bad idle, they are also cheap and easy to replace .. just my 2c Enjoying this content very much!
Honestly I like seeing John get more confident and riding larger bikes! Nothing wrong with small bikes but seeing someone's journey into two wheels is fun for me. 👍
Honestly this bike is way easier to control compared to a mini bike with 25 horsepower and 6” wheels and a 30” wheelbase. I am aware that the CR500 can fool you with how fast it’s going. So gotta be careful!
When they get this bike running right, there all gonna be sacred of it most likely. The 250r an 500r have a strong powerband hit and tend to throw people off so fast its impossible to stop it. I bin riding 30+ years and I wouldn't ride one anymore. I flipped to many. Lol
I had more fun on my yz 80 than my pe 250. Suzuki pe was a ripper. Rm for the woods. But that 80 was a screamer and you could throw it all over the place. But that old 250 sure could dig a sweet trench. My brother had a yz 490. Enough said
@@allenmichaud1605 I've rode a yz490 and there fast bikes. Hard to hold onto in the woods. One blip of the throttle and it throw you throw the woods so fast you better hope there's no turns. Lol
Great video. I restored an 85 CR500 a few years back on my channel. The Clutch cover was repaired with jb weld and an epoxy due to being made of magnesium which eventually rots. Replace the reeds. Put new jets, air screw and a new Honda choke assembly in the carb. Starting the CR500 takes technique if you want to keep your leg. Slowly kick it through the intake stroke to where you feel the piston coming back up and compressing. Stop, do not let it come to top dead center. Let the kicker come back up. Kick it slowly about 1 to 2 inches. You will feel a little relief in compression as you slightly pass top dead center. Stop. Let the kicker come back up. Now you will be able to kick it with ease because it is on its full intake stroke. By the time your leg gets to the compression stroke you will be be well into your kick. Do not get over confident with this technique. Follow this technique and anyone can kick over the Cr500. I start mine in running shoes. Good luck i am sure you will have it starting and running great very soon.
Big bore two strokes will always be my first love. Going all the way back to my 1979 KTM 420, there is nothing quite like that level of power in a lightweight chassis.
Ktm 440 mxc in sx 250 2024 model frame here. 440cc is like 500cc but it revs alot higher and power is more usable. One of the best bikes i have ever had.
I've been riding & racing 500's my whole life and still have a primo 93 500. Started with an 81 CR450 then to an 85 CR500 then the 93, bought them all brand new. It took me a bit to get the starting drill down on those Bad Boys but once you get it you'll never forget it. The first thing is to lean the bike over to make sure you get a little fuel out the overflow, then open the throttle wide open hit the kill button and kick it through 4 or 5 times with the choke on to prime it, then work the kick start through till you get it tight at the very top then kick as hard as you can all the way through with the throttle cracked open. Also they are notorious for the choke circuit plugging up which makes them nearly impossible to start. a quick way to see if the choke circuit is plugged just put a small amount of fuel in the spark plug hole, if it fires up it's probably plugged. I was usually able to light er up in 2 or 3 kicks as long as the motor is in good working order. I'm 66 now and don't ride the 500 as much since I got a KTM 300 with electric start, but still love to sling a leg over the 500, especially out in the desert where you can really let er sing, there is no feeling like it. The 85 was always the hardest to start. Its really important to get the jetting spot on that helps a lot. Loved the vid and am always happy to see the old 5 hunny's being revived & restored. Short shifting them is definitely the hot ticket. They make a great woods bike if you short shift and ride the torque curve and the motors last forever. Enjoy
Watching Ike effortlessly fire the bike is like the reel going around where the guy hands the racer his beer and fires the racers bike up for him and spins it around
I'm 38 years old, starting when I was in 5th grade I rodeva 1991 CR500r that was bored over with a Wiseco piston, power reeds all sorts of tricked out. It was scary fast yeah, I added a 85g flywheel weigh to be able to ride it in the trails without flooding spark plugs. Even before the upgrades it was a pig to start. The easiest way is to cycle the Piston to top dead center using the kick-start until you hear a distinctive hollow "plunk". Once you hear that bring the kick-start all the way to the top and send it through the dirt! Almost guaranteed to fire every time! Great seeing yall have so much fun with this, making me want to bust out some tools and go find a project!
2001 CR500. My favorite bike I ever owned! Have fun guys! They are more fun than anything else to ride. Remember the wise words of Dave Aldana. "You don't know how fast you can go until you fall off." I heard him say those words when I was 4 yrs old and have ridden that way my whole life. I am 56 now. I survived. HAHA! Great fun!
the dampening in the exhaust is not only sound dampening, it also creates a delay and high pressure in the end of the exhaust, only this way the expansion part of the exhaust will function like it should, its like 20% more effective with clean dampening material, also means like 20% more horsepower :)
From karts to mini bikes to dirt bikes. I've gone through the same progression and just love riding the dirt bikes now and my mini bikes are collecting dust lol.
I used to have one of those! Man, that brought back memories... This bike separates the men from the boys. If you don't ride it hard, it will ride you hard. It's a monster. Of all the bikes I've owned in my life I miss this one the most.
The grey transmission oil is aluminum from the clutch. Honda CR has aluminum clutch plates for weight reduction ans better cooling but they wear rapidly.
Hey what elevation and temperature are you riding in? I’m very skilled and knowledgeable on the 84-86 jetting and would like to help you getting the jetting up to par. The fmf jetting is close but is going to change as the weather gets colder.
I'll be right there! There's nothing like a two-stroke five hundred! You gotta be in good shape, and know what you're doing to ride those things on the pipe for any length of time. I wish they still made them.
Would love to see a restoration of this bike. You guys got one hell of a ride there. It been a while since I've owned one, still kicking myself for ever selling the cr500 I had.
I'm in the same boat with regretting selling mine, I raced hill climbs with mine when I was a much younger man, going from a 250 to this monster was an eye opener for sure
@CarsandCameras all dirt bikes with a clutch that sit for a long time like that and the clutches get kinda sticky always have grey oil when you fire em up and ride em like that. It’s nothing to worry about it. Put some atf transmission fluid in it and chnshe the fluid every other ride until it’s not grey anymore. ATF is perfectly fine to run in them to. I run amsoil in my 2 strokes. Shifts like butter. I use cheap O’riellys ATF to get the grey to go away. Doesn’t take much oil like a quarter of a quart or something like that to fill it so one quart goes a long way.
Amsoil for the gearbox after every ride. No other oil makes it shift so buttery smooth. Just sold my '88 this year. I'm 60 now, broke my heart. Anyway, never split the cases in all those years since I bought it in 88. I swear by Amsoil.
@@MelWhite-fu4if yea amsoil synthetic atf is what I run in mine and I could literally tell a huge difference. Most bikes especially two strokes when coming to a stop are hard to find neautral sometimes with amsoil it goes right in. I run amsoil in all my stuff, My 05 GTO that’s built and procharged, my ‘13 Sierra crew cab with a built ls, dirt bikes, sxs, it don’t matter. And yea I had a 89 KX250 I restored completely and a week after I restored it somebody stole it from me. Never seen it again. I had a 92 CR500 I got for cheap but the frame was smashed and rusted, but had a fresh rebuilt 01 CR500 engine in it bored.040” over I rode it one time and took it apart and sold the motor for more than what I paid for the bike. I still got all the other parts except the frame. At that time I didn’t have a welder, or I would’ve repaired the smashed section of rail and redone it.
One of the few videos out there that made my adrenalin run just by watching it. I never had the opportunity to ride a 500, but was able to ride a similar year 250 back when they were still new and that terrified me. I hate to admit it, but this bike is way too much for me, even on my best day. Great video. I can't wait for the next one!
I had a 1987 CR250 that I supermoto'd with 17's, put a new reed cage in it, fmf pipe, new chain and re-geared sprockets etc. Took it for about 3 rides and sold it. I like being alive. That thing was terrifyingly fast, especially for me a 5'5" 130lb mini man.
We used to install compression releases on bug bore dirt bikes JS. LOVE you guys know you make an old man happy every new video. Keep them coming n thank you all
Cr 500 starting tip. Slowly kick it over until you get it to catch at the tallest point possible. Then give it one good kick. Like ike did on the second kick earlier in the video. 🤙🤙🤙
Good on you "Hinson Shaving" for sponsoring (I'm already shaving with Hinson and they are great and very cost-effective.... I'm not even getting paid LOL but if you're smart and have stubble you'll do well to be using them)
Order a Moose flywheel ! It makes all the difference if you're not on the power band the whole time you ride. It helps with starting too. AND ... put a tool bag on the front number plate with a cordless drill and a case of new spark plugs!!!😁But seriously, a hundred of we the CR500 owners club members must have laughed at you for not knowing about the kick-starting issue. It is endemic, all-inclusive and unavoidable. Get the cordless!
Panthera makes an electric starter setup for these CR500's. But man are they pricey, they're oh so worth it if you're gearing the bike for woods riding. I couldn't imagine having to kick start this thing every time you stall it. Your leg would either twice the size from when you left home due to gained muscle or non-existent from falling off. 😁
@@SocketSlinger I have a 1981 YZ 465H that I bought off of my younger brother about two or three years ago as a long term project. But it's currently a basket case as he had it apart when I bought it. Sadly it's going to take a while before I can focus on buying parts for it. There's just too many more important things to spend money on at the moment.
@Slane583 man I get that, I pray something will come about to where you can finish that beast. I generally just roll, assplop the seat while simultaneously kicking them into second on them big bore two strokes while praying I don't whiskey throttle it lmbo. I'm 43 6'1" 200 lbs and have messed up my legs at a young age trying to crank some of them big ones and many wrecks, so I have been starting them like this for over 20 years. If you are close to NC and Decide to sell it I know many people that would be interested.
@@SocketSlinger The thought has crossed my mind a couple of times, then I wipe it from my head because I don't actually want to part with it. It's more of being frustrated with the fact I have too many things to work on, no place to do it and not having never ending funds to do it with. I've priced out parts to get it going and if I hoarded parts I need a chunk at a time I'd have everything I need. But then I get distracted like a bird with the next shiny thing that shows itself. I have too many hobbies and not enough money. 😁
Great job putting the CR500 together. I've been wrenching and riding two strokes for about 30 years now. Here's a few thoughts: 1.) The silver-milky oil is a combination of aluminum clutch material and a coolant-oil mixture. The reason it was so runny was because water was mixing with the oil. Someone mentioned the cases being eaten out, but I'd check the water pump seal first. If the seal fails, the higher pressure coolant will push past the seal into the clutch case and mix with the engine oil. Remember that the water pump is driven off the clutch side via a reduction gear. My KX500 did that once and I had to replace the seal. 2.) Mixture Leanness: Two strokes are intensely mixture sensitive especially to leanness (i.e. too much premix will thicken up the fuel and hose the A/F mix too lean; a crank seal will suck in air, lean the mixture and hole the piston or melt the piston at the exhaust port). Make sure your mixture is spot on. Check to make sure that the bike was up-jetted for the pipe (or lean mixture results will suck (see above)). If your spark plug is oil fouling and the mixture is spot on, suspect the clutch side crank seal. Make sure your choke, throttle access to the carb, and anywhere air can enter the carb is correctly sealed. I had my choke unscrew on my KX500, which lead to a runaway motor, new piston, rings, and cylinder replating (BTW, pulling the spark plug did not stop the run away). Chances are, if that happens, you won't be able to save the piston and cylinder in time: an ounce of prevention beats a ton (rather than pound) of cure. Check the intake boot for dry rot, cracking, or tearing; again, a lean condition will lead to a bad day and costly repairs. Check the exhaust port: look for smearing of the piston onto the rings, this will indicate the A/F mixture is off. 3.) Starting the CR500/KX500: get the piston to the top of compression stroke, slowly put pressure to get the bike just over the "hump" of the top of the piston stroke. Stop, and reset the kickstarter to the top. Jump up and give it a helluva whallup downward with the MX boot on. If you do it wrong, you're leg will crumble and the kickstarter won't move (just like your video today). If the bike is running well, it should start in 2-3 kicks max. (choke on cold and no choke warmed up). 4.) Plan on replacing your rings, it's a meager price to pay for 2 stroke performance and simplicity. 5.) Transmission sliders (what the shift forks move to engage transmission gears) or gear cogs are infamous for breaking. 2nd is the worst, because 1st is mostly useless on a 500, and most people would dump the clutch in 2nd. 6.) Get V-force reeds or Boysen reeds; it'll give you much better throttle response for little $$. 7.) There's better carbs than the stock carb for a CR500, but it can get pricey. 8.) 2 strokes are not intended to be lugged like a 4 stroke. Stay in the powerband, rev it, and hang on. If you lug the bike, you're going to just foul your plugs and not get the riding experience the manufacturers designed the bike to do. 9.)The bike looks thrashed, the swingarm bushings will most likely be trashed as well as the front tire bearings. 10.) Get fork protectors: it'll keep the forks protected from moisture, rusting, and pitting and keep the fork seals working better for a longer time. 11.) Purchase the latest "Motorcross and Off-road Performance Handbook" by Eric Gorr: it has a ton of tech tips and articles as well as what specific plague MX bikes from 80-500cc engines and most popular MX manufacturers (Honda, Kawasaki, Suzuki, etc.). DM me or contact me, and I'll provide whatever assistance I can over the phone, via email, or in person (I'm not too far away from you on the Atlantic seaboard). Lastly, if you'd like, I can bring my KX500 by and we can do some riding (you're welcome to ride the KX500 which has a brutal punch in the balls and demands to be noticed when it gets on the powerband).
I knew I forgot something: you clutch basket fingers are grooved. This will cause the clutches not to release properly, making the clutch both prematurely "grabby" when starting from a stop and less likely to release as fast as desired when the SHTF moment that you want the clutch to work best. Check the clutch inner hub for grooving as well. The needle bearing on your clutch shaft is silver due to the aluminum powder going into the bearing. Replace it unless you want that bearing to seize on the clutch shaft, wipe out your clutch, and won't disengage (most likely at high RPM and about when you'd want the clutch to release when the SHTF moment. If you want a more durable clutch, get a Hinson clutch basket and components. You can also get a lockup clutch (used on the Yamaha Banshees) which will apply the full clutch force when the clutch is fully engaged). The fuel spitting out the carburetor is most likely worn intake reeds. The two stroke uses pressure pulses from the exhaust to scavenge the cylinder which is supposed to be stopped by the reeds. And you really should have the airbox and boot to the carb as well. The JB Weld turns blue when exposed to the green coolant. An MX bike is designed to turn fast on dime and give 9 cents change. This makes them prone to a bad headshake at high speed. Congratulations on putting the fork protectors on it and adjusting the jets. Once you get accustomed to the powerband, you can keep the front wheel about 6-8" off the ground and steer the bike "moderately" like a unicycle on an open field.
Really enjoyed this video, brings back some good memories. Still have my 90 model 250 but it’s been a lotta years since I owned a 500. Been right at 30 years since I worked for the local Honda dealer, I was always the guy who had to test ride these after we repaired em for a customer. The other mechanic from back then still works there and a good buddy of mine, he’s not as terrified of them as he used to be. He’s only 5’6” and hasn’t had another growing spurt yet, lol. The 125 was more his size in the R model 2 smokers. Most of the 2 stroke stuff I had been tasked with fixing had been usually looked as if a blind chimpanzee had been turning wrenches on it when they arrived which is commonly the case. Usually had the air boxes drilled and 8 out of 10 wouldn’t take the time to add screens to the holes afterwards or jet them up. Adding the air box back to your bike will undoubtedly help with your idling and midrange. While you’re into it this far run another compression test after replacing your crank seal to get a better idea of what you’re dealing with for cylinder and piston. I know that I’ve been into more than a few over the years that they’ve tried to do port work on themselves and ended up running the sleeves. After that they either had to buy another cylinder or we’d have to replace the sleeve in their cylinder, then you’re left with an inefficient port that puddles fuel. If you guys have a bore scope it wouldn’t hurt to look in the cylinder to see what you’re working with for wear and timing in your stroke as far as when your piston passes the intake and exhaust for the timing. I’m not positive that’s any of the problem you all are dealing with but I know for a fact that incorrect port timing makes them hard to start and really kills the power on the two strokes. Hopefully this’ll give you guys some ideas of where to start looking for solutions to what you’re dealing with. Good luck with the bike and hope it all works out for you.
When Charles said he's gonna put the muffler back together without the packing I was like "no no no no no", I could just feel my eats starting to bleed knowing how lound it will be... ya should know, remember the 670 skidoo snowmobile engine how stupid loud that was lol.... then a few minutes later the honda started and YEP its loud lol
We had one of those when we were kids my brother was a big guy when he was 18 years old he had that exact 1985 CR500 but it was complete withe gold rims, it was a complete bike. It was hard to get it to start up but that thing was a monster it was really hard to crank up because it had so much compression but you put the boot on and crank and cranking once that thing came to life it was a monster 1985 CR500 was a total Beast
3rd gear takeoffs were standard and no big deal in the 80;s & 90's on the CR500. I amongst probably thousands more just knew that whoever was pulling the higher gear was probably going to win the race to the next turn. I also remember using copper clutch plates to transfer the heat out of the clutch, too. Properly running 500 two strokes had the low-mid range grunt to roost out of the gate in 3rd gear. 1st & 2nd gears only slowed you down in an mx race. People are so afraid of those bikes now, but actually if you rode with a clear head, in your limits, they were very forgiving and could pull you out of a bind. It was all in the clutch. Need more drive, feed her more clutch. They were fun. My stock '86 with pro circuit pipe & jetting, started easy, ran smooth and pulled 3rd & 4th gear speed wheelies with no problem. Just make sure the bars are turned to the left a bit when you start em, or else they could put a gash in your knee when it decides to buck. Haha We started them barefoot though. No big deal. Just kick it all the way through. Fun times.
Hi cars and cameras I want to let you know that I am 13 years old you have have inspired me to be a mechanic and be confident Thankyou for everything you are a great teacher I have learned a lot of things I prefer cars and cameras than vice grip garage because you guys are funny ,Thank you guys so much ❤
I used to have a 1985 kx500. It was also a PITA to start. It was mostly clapped out as well. It had 2 states of running, either it wouldn't start, or it tried to kill you every moment it was running. I miss that bike 😥
Two smokers can last as long as any other bike, you just have to know how to take care of them (In response to the statement they only last x hours). Ride them enough to keep the seals wet, rings from sticking, carbs clean, de-coke the pipes and use only the best premix; my preferred blend Golden Spectro mixed with Blendzall/real castor oil. I have owned many two stroke street and dirt bikes (first street RD400, Dirt PE400), and love them above all other engine types...SMOKERS forever! Great jobs boys..and yes the CR500 can be a hand full.
'DIRT BIKE FAB' did an episode describing the Right way to start the CR500 while he was rebuilding Paul from 'Fab Rats' bike.Couple motor tips in that for you too viewers.Kevin did a series on the rebuilding,and most of the tips will work on 2-strokes of all sizes.
i had a 91 for 25 years it was like new . was all ways a little hard start cold . got to old to ride it so i put it on ebay .the guy that won the bid was Henry Wiles tt racing champ . he had soft shoes on and hop on it to start it and i said man dont get hurt starting that thing.he gave me a look and said did you forget who your talking to and 2 kicks and he was gone. he had just won the peoria tt a record 14 times very great guy.
Good to see the leg is bouncing back. i felt that pain just watching. Still have dents in my chin from trying to kick start quads with tennis shoes on... Don't miss those days lol
I went from a 125 4 stroke to a 380 2 smoke, and man what a game changer, been wanting a cr 500 in a nice new aluminum 450f frame, im just too poor and dumb to work on stuff.
Kool Video ... Just happen to come across this on you tube...Myself i have a 89, CR500, Mint Shape. My Honda dealership where i live, has been trying to get me to sell him my CR500. And you never know i might do a trade for a VTX1300, not sure yet ! ... I'm almost 67 now and i don't ride it, Yes it was put away the right way. Most powerful bike i have ever owned was a Honda XR650R uncorked with a stage 2 HRC Kit . Just a little quicker than the CR500. The CR500 would be almost at my back rim on the XR650R all the way threw the gears. The 89 - 91 are the most sought after CR500'S on the market. Anyone interested drop me a note , comes with lots of plastic and mods i have done with this CR500. Might as well let some one have joy riding this icon motorcycle. Note: Never raced was my fun bike '' enduro '' .. Sure had fun with it...Mint Shape as all my bikes are. ( 1982 Yamaha IT465 - 1976 Honda MR250 100% restored all NOS - 1989 Honda CR500 - 1977 Yamaha XT500 - 2003 Honda VTX 1800C - 1983 Honda CB1000C )
YOOO GUYS these bikes are meant to run with the stock air box, air filter, and packing in the exhaust putting these things on might make it run better. It may also need new piston rings and I noticed that the clutch basket had some pretty good grooves in it so y’all might want to replace it soon too. it’s awsome to see all the new parts you guys are throwing at this thing and so far y’all have been doing it justice for sure 👍
Turn the choke knob in or out to adjust the idle and check the Reeds for hard starting problems they need to be ceiling nice and tight replace with boyesen reeds
We had a dirt bike neighborhood when I grew up. In 85, I watched a 220lb guy take a new one off the truck, fire it up in shorts and waffle stompers. He hit fist gear and she came up so hard and fast when he planted his foot the bike came over on him and we saw his knee get almost 360 Degrees of rotation as the bike fell back on him with out the boot moving. He was in surgery for 6hrs. And took 2yrs until he walked again. Go easy boys. This is the the beast of all beasts. The guy who got the bike at discount broke his foot a month later w a kick back.
Please keep and improve this! It doesn´t get anymore homebrew than Y´all do, I love two strokes and this animal has earned a place in Your fleet. It might be old and clapped out but still has enough oompf to straight kill a guy(s leg). We should respect that. Honda was going against Maico with this and Maico was the meanest cat around. We need to see this in context of the time.
I can't believe how many people don't know how to start a big bore dirt bike. First put into 2nd gear and rock bike back and forth with choke on it will draw fuel into cylinder second don't kick, jump lifting left foot off peg with all your weight on right foot and complete throw from top to bottom of starter travel. It will usually start 1st kick. Always worked with my yz465 and cr500
I used to have one of these... Either an 85 or an 86. All I remember is it was the year Honda stopped upping the compression. The next year they went down because of the starting issues. (And the broken legs) the guy I got it from said the kicker folded up and kicked back through, THROUGH the sole of his motocross boot! Regardless yours starts way better than mine did. I put some lights on it and rode it on the street. (Melted it down twice) the last time I rode it I passed two buddy's that thought I was an idiot for riding it and had left me behind. They were doing 110 and I came smoking (literally) past them! And fyi the aftermarket kicker was shorter to turn it over faster. You might want to look into something like that.
Hey if you like vintage Honda motorcycles etc then you are going to love our sponsor, waterbed thermostat kings, for all your bedding needs. Love the video though and how thorough you are with explaining the parts as you are replacing them.
I gotta say, these dirt bike videos excite the heck out of me, any 2 stroke dirt bike 80cc's and higher yknow its gonna be a good vid. I cant wait for them to fine 3 dirt bike or a 125cc.
Man I feel for John. I've ALWAYS wanted a cr500, and at 5'9" 148 lbs, even with fairly decent leg muscle the couple I've ridden were a pain in the ass to start. Both were also clapped out heaps that you had to kick over and over.
Fill till u spill baby! My dune queen (77 whp 2003 yz450f) holds all of its oil in the downtube. It's so difficult to get the level right. Yeah man that old steel frame is with the 5 titanium valve head and 4 speed gearbox, I did a quaiffe billet connecting rod and a diamond billet piston and it's now a 505cc. Much stiffer Hinson clutch and basket, magura hydraulic conversion, 18 year old, $4700(back then i was sort of on flow for pro circuit so i got them for $700 which was just for the labor) pro circuit suspension I send back to them every year for a refresh, I ported and polished the head, full titanium pro circuit exhaust with a carbon can. I cannot remember exactly what silencer it is because my back wheel rubbed the logo off but it's the best you could have bought for horsepower back then.

I own a 2023 yz250 2 stroke and a 2021 yz450 now.
Get a set of Vforce3 Reed valves there not to expensive and they will give you massive gains in throttle response and better fuel distribution going into the crankcase by far one of the best upgrades when it comes to 2 strokes.
love the old 500s ive still got my cr 500 but since ive owned it in last 8 years ive basically put my cr500 in Crf 450 frame and it looks awesome now love old 2 smokers and smell you cant beat it
My buddy has an 87 Cr 500 that is really hard to start unless it's warmed up. One year, we put a top end on it with new jug and head. We hoped that it would be easier to start, but no. He threw another 200 in parts with no luck. He finally decided to give up on kick starting it, and he just bump starts it when its cold. He will get another person to drive his golf kart, and he will hold on with his left arm to get up enough speed, then he drops it into second. It always starts right up when we bump start it but I've never seen it kick start when its cold.
I have a 1983 Honda V45 Magna, I ask it nicely to start every time, and to start running. So you aren't alone to asking an old Honda to start nicely for you.
one thing i suggest as i had this same issue. Check in the venturi of the carb just ahead of the slide. theirs two little ports in the bottom that allow the idle jet fuel to be drawn up into the carb. Had the same issue and thats all it was. blow through with some cleaner. If you look up a diagram of how the idle circuit works you'll see the holes im talking about.
This makes me miss my YZ 490...dang that thing was fun. I was the only one nuts enough to hammer the crap outa that thing and once in Wyoming opened the throttle completely and let it rev out full speed. (Wyoming is really flat) Just hauling ass out on the open prairies on nicely manicured dirt roads. Felt like 120 MPH with how fast the landscape was whizzing by even in the distance. A CR500 would be even better, I heard they tuned them down after 1986? due to how many people were getting hurt with all the power.
The gray transmission oil is a direct indicator of a bad crank seal. It would be more of a white color if there was coolant in there. Also mix the oil and gas at 32-1 or 4 oz of quality oil to one gallon of gas. You usually increase or go up in jet size for a aftermarket pipe. If it had upgraded reeds those usually require smaller jets. So if you do them both together you’ll have to play with the jetting.
in 1985 i was 16 and my 19 year old cousin bought a CR500 new, we thought the 250cc jump from a 125 was awesome, the jump from a 250 to a 500cc was scary.. lol had a lor of fun riding dirt bike in southern California.
i think ike raging at the bike while trying to start it is one of the most relatable things ive ever seen. Great video hope you guys make more bike vids
I used to have a husqvarna 1986 motocross CR500 2 stroke (very rare now) if you think the Honda 500 was a hand full you ought to try the Husqvarna CR500 it has the kick starter on the left hand side of the engine just to make it even more of a challange to start..you could lift the front wheel in 1st,2nd,and 3rd with just the throttle no slipping the clutch this thing was an animal.
Wow, I remember when the 500 came out! It was untouchable by anything out there. I remember i tried to start one and almost broke my leg. Even trying to push starting it was a bitch. Thank you for the memory of the pain. Ray
I have a lot of experience with big bore two strokes and two strokes in general. First off. The milky oil out of the transmission isn’t milky. more than likely it had been a while since the last service and that is clutch friction material (very common). Secondly I would pull the reeds out and check to see if they are sealing off completely. You should not be able to see light when looking through the intake tube towards the reed petals. A 2 stroke should never spit fuel out if the carb. That can be a definitive cause of a rich jetting issue. As air goes into the carb it draws fuel then gets pushed back out because of bad reeds and draws more fuel. Then Gets sucked back in again drawing more fuel. Third I would highly recommend repacking the exhaust. 2 strokes rely on back pressure to have bottom end power. Also an air leak is the best thing you could have done for an old 2 stroke that has been sitting. air leaks are a very common cause of 2 stroke failure. You guys are on the right track to having a great bike.
Hey mate Liam from Australia, that’s starts completely normal. If u watch back through the video wen u kick it your not getting a full kick in it all the way down to the peg an also As many other people have said ur not starting it properly. U have to put it in 4th gear an rock it back and forth on the ground for about 10 seconds then 3 3 slow kicks get it at the hardest point of the kick start an absolute jump on it, an I mean wen ur left leg is on the bike start take all your wait off the stand an throw it all into The one leg that’s kicking u will start it first go every time
I had a chance to ride a friends built '86 CR500R, Keep in mind I raced a 9 second busa for five years that I did not find very scary, but a built fresh engine on a CR500r is penty scary. I wish you guys all the luck in the world with that thing, and be cautous or it will bite you.
Hey Brother, I own a CR500, KX500, LT500 (Quadzilla), CR480, YZ465, RM465. My best friend also has a KX500. I start all these bikes, so my point is...I kinda know how to do it. First the 85 CR500 is notorious for being hard to start, I think it's because it has a small flywheel, and a high mounted kicker. So you guys know about leaning it over, this is because the choke is not very effective on a 500, because it doesn't spin the motor over very fast when kicking. So leaning it over spills fuel into the carb throat (a super choke). Now you need to draw the fuel into the chamber, this takes "sissy kicks". Slowly push the kicker all the way down, choke on throttle off, don't kick it unless you just want to get tired, push down with foot. Sissy kick until it goes phew out the muffler. Most likely that will be 7 or 8 sissy's. If it went phew out the muffler on sissy number 7, that tells you, your bike (the way it is jetted) wants to start on #7. So next time, sissy kick it 6 times, then a full hard kick from top to bottom, usually with throttle off, and it should start. I can usually cold start any of my bikes in 1 or 2 kicks. Your bike smokes a lot when running, usually an indication that too rich pilot jet or air screw (unless you went way overboard with premix oil). The airscrew is fine tuning for the pilot jet, so use it to tell you if you need to change the pilot. Start and warm/ride the bike, then stop, turn idle speed up a little, and turn air screw in or out until you get best idle. Engine should rev quick to 1/4 throttle, and drop back to idle almost as quick, if it hangs, turn screw in a little to richen. This will make it easiest to start. Your carb probably calls for 1.5 turns out (per manual). If it is ...say 3 turns out, you are adding more air to the idle mix...because the pilot jet is too big, compensating with air screw.
Back in 1988 I was riding a yz465, then a yz 490, my friends had a cr500, we were at a sand drag and I took the 500cr for a ride after a few beers I hit a berm coming out the river and it made me hit wide open throttle I held on banging gears doing a long wheeley the crowd watched not knowing I was crapping myself.
I had an lt500r a handful of years ago, bored to a 560cc. I found it in my best interest to turn the ignition off while setting TDC. Turn on the ignition and kick. I was barely pressing it once and it fired, the kick start went down all the way and came back up so hard it literally took a small chunk out of my tennis shoe.
I learned the cheap is expensive lesson with my 05 crf450x as well with similer issues and have spent close to half of what i bought it for ,into it again and its still not runing 100%.Though im getting closer it is really frustrating making supposedly the right changes and it either still not wanting to run or just getting worse. Wish you guys luck on getting it to run correctly so you can enjoy it a lot since big dirtbikes are a lot of fun
It could be aluminum from the clutch basket and clutch pack , these engines use qt the most a quart of oil so ut gets dirty quick hinse the reason it needs changed after every riding session

Hi. You might heard this already, if you are low on compression the enginge will run rich. So it might be a good idea to check the piston and ring... And also, a reed valve engine should never spit back the fuel thru the carb so i’m guessing it’s time to rebuild the reed valve... Keep up the good work, boys! 👍
That's exactly what that bike needs it's way low on power cr 500 is a beast not recommended for rookies lol😂
They said it was nearing 150psi which is within spec. I wonder if the reeds themselves are bad. The reeds seem to get over looked quite often because they don't wear out as quickly as everything else. Even if they don't have corners chipped off they might be hanging open enough to suck air. :)

A little dicey though spinning the motor that fast without oil though, no?
@@christianrios6295 Honestly not really, you would be surprised how little oil is in a 2stroke btm end
Doesn’t help that Outlaw Karts on dirt ovals use the cr500 as their open motor…
The exhaust leak is still there and will effect how it’s running. The pipe gets a donut and the flange attached to the motor gets a metal gasket as well.
Two stroke pipes always seem to leak though
The Big CRs were always hard work, they always oiled up if you didn't have a big space to open them up, also if I remember correctly the transmission case oil also lubricates the wet clutch so they can get messy, oh yes you might want to replace the flywheel as the magnets weaken with age/heat .. and don't be surprised if it wants new rings/piston & a rebore every few hours of use ..... for all those negatives just a few moments hitting the power band are worth all the hassle.
I did notice what looked like some ridging in the clutch basket, if it's not too deep sometimes a light file can help remove them and stop clutch stick/judder.
One other thing you might want to check and or replace are the reed valves, they do get lazy and stick open making for hard starting and bad idle, they are also cheap and easy to replace .. just my 2c
Enjoying this content very much!
A restoration series would be super cool on this bike.
Yeah that's the Reed valves they're holding slightly open causing fuel to spit out through carburetor during the piston downstroke
Honestly I like seeing John get more confident and riding larger bikes! Nothing wrong with small bikes but seeing someone's journey into two wheels is fun for me. 👍
Honestly this bike is way easier to control compared to a mini bike with 25 horsepower and 6” wheels and a 30” wheelbase. I am aware that the CR500 can fool you with how fast it’s going. So gotta be careful!
When they get this bike running right, there all gonna be sacred of it most likely. The 250r an 500r have a strong powerband hit and tend to throw people off so fast its impossible to stop it. I bin riding 30+ years and I wouldn't ride one anymore. I flipped to many. Lol
Yep, John sent that thing pretty darn good 😅

Gotta say I am loving the longer video lengths since you guys went to one episode a week 💪💀 you can really get the details in there and Im here for it
Going from a 20min to 50 min video really makes me happy
Great video. I restored an 85 CR500 a few years back on my channel. The Clutch cover was repaired with jb weld and an epoxy due to being made of magnesium which eventually rots. Replace the reeds. Put new jets, air screw and a new Honda choke assembly in the carb. Starting the CR500 takes technique if you want to keep your leg. Slowly kick it through the intake stroke to where you feel the piston coming back up and compressing. Stop, do not let it come to top dead center. Let the kicker come back up. Kick it slowly about 1 to 2 inches. You will feel a little relief in compression as you slightly pass top dead center. Stop. Let the kicker come back up. Now you will be able to kick it with ease because it is on its full intake stroke. By the time your leg gets to the compression stroke you will be be well into your kick. Do not get over confident with this technique. Follow this technique and anyone can kick over the Cr500. I start mine in running shoes. Good luck i am sure you will have it starting and running great very soon.
Big bore two strokes will always be my first love. Going all the way back to my 1979 KTM 420, there is nothing quite like that level of power in a lightweight chassis.
Ktm 440 mxc in sx 250 2024 model frame here. 440cc is like 500cc but it revs alot higher and power is more usable. One of the best bikes i have ever had.
I've been riding & racing 500's my whole life and still have a primo 93 500. Started with an 81 CR450 then to an 85 CR500 then the 93, bought them all brand new. It took me a bit to get the starting drill down on those Bad Boys but once you get it you'll never forget it. The first thing is to lean the bike over to make sure you get a little fuel out the overflow, then open the throttle wide open hit the kill button and kick it through 4 or 5 times with the choke on to prime it, then work the kick start through till you get it tight at the very top then kick as hard as you can all the way through with the throttle cracked open. Also they are notorious for the choke circuit plugging up which makes them nearly impossible to start. a quick way to see if the choke circuit is plugged just put a small amount of fuel in the spark plug hole, if it fires up it's probably plugged. I was usually able to light er up in 2 or 3 kicks as long as the motor is in good working order. I'm 66 now and don't ride the 500 as much since I got a KTM 300 with electric start, but still love to sling a leg over the 500, especially out in the desert where you can really let er sing, there is no feeling like it. The 85 was always the hardest to start. Its really important to get the jetting spot on that helps a lot. Loved the vid and am always happy to see the old 5 hunny's being revived & restored. Short shifting them is definitely the hot ticket. They make a great woods bike if you short shift and ride the torque curve and the motors last forever. Enjoy
Watching Ike effortlessly fire the bike is like the reel going around where the guy hands the racer his beer and fires the racers bike up for him and spins it around
I'm 38 years old, starting when I was in 5th grade I rodeva 1991 CR500r that was bored over with a Wiseco piston, power reeds all sorts of tricked out. It was scary fast yeah, I added a 85g flywheel weigh to be able to ride it in the trails without flooding spark plugs. Even before the upgrades it was a pig to start. The easiest way is to cycle the Piston to top dead center using the kick-start until you hear a distinctive hollow "plunk". Once you hear that bring the kick-start all the way to the top and send it through the dirt! Almost guaranteed to fire every time! Great seeing yall have so much fun with this, making me want to bust out some tools and go find a project!

"You don't know how fast you can go until you fall off." I heard him say those words when I was 4 yrs old and have ridden that way my whole life. I am 56 now. I survived. HAHA! Great fun!
the dampening in the exhaust is not only sound dampening, it also creates a delay and high pressure in the end of the exhaust, only this way the expansion part of the exhaust will function like it should, its like 20% more effective with clean dampening material, also means like 20% more horsepower :)

@CarsandCameras all dirt bikes with a clutch that sit for a long time like that and the clutches get kinda sticky always have grey oil when you fire em up and ride em like that. It’s nothing to worry about it. Put some atf transmission fluid in it and chnshe the fluid every other ride until it’s not grey anymore. ATF is perfectly fine to run in them to. I run amsoil in my 2 strokes. Shifts like butter. I use cheap O’riellys ATF to get the grey to go away. Doesn’t take much oil like a quarter of a quart or something like that to fill it so one quart goes a long way.
Amsoil for the gearbox after every ride. No other oil makes it shift so buttery smooth. Just sold my '88 this year. I'm 60 now, broke my heart. Anyway, never split the cases in all those years since I bought it in 88. I swear by Amsoil.
@@MelWhite-fu4if yea amsoil synthetic atf is what I run in mine and I could literally tell a huge difference.

Great job putting the CR500 together. I've been wrenching and riding two strokes for about 30 years now. Here's a few thoughts: 1.) The silver-milky oil is a combination of aluminum clutch material and a coolant-oil mixture. The reason it was so runny was because water was mixing with the oil. Someone mentioned the cases being eaten out, but I'd check the water pump seal first. If the seal fails, the higher pressure coolant will push past the seal into the clutch case and mix with the engine oil. Remember that the water pump is driven off the clutch side via a reduction gear. My KX500 did that once and I had to replace the seal. 2.) Mixture Leanness: Two strokes are intensely mixture sensitive especially to leanness (i.e. too much premix will thicken up the fuel and hose the A/F mix too lean; a crank seal will suck in air, lean the mixture and hole the piston or melt the piston at the exhaust port). Make sure your mixture is spot on. Check to make sure that the bike was up-jetted for the pipe (or lean mixture results will suck (see above)). If your spark plug is oil fouling and the mixture is spot on, suspect the clutch side crank seal. Make sure your choke, throttle access to the carb, and anywhere air can enter the carb is correctly sealed. I had my choke unscrew on my KX500, which lead to a runaway motor, new piston, rings, and cylinder replating (BTW, pulling the spark plug did not stop the run away). Chances are, if that happens, you won't be able to save the piston and cylinder in time: an ounce of prevention beats a ton (rather than pound) of cure. Check the intake boot for dry rot, cracking, or tearing; again, a lean condition will lead to a bad day and costly repairs. Check the exhaust port: look for smearing of the piston onto the rings, this will indicate the A/F mixture is off. 3.) Starting the CR500/KX500: get the piston to the top of compression stroke, slowly put pressure to get the bike just over the "hump" of the top of the piston stroke. Stop, and reset the kickstarter to the top. Jump up and give it a helluva whallup downward with the MX boot on. If you do it wrong, you're leg will crumble and the kickstarter won't move (just like your video today). If the bike is running well, it should start in 2-3 kicks max. (choke on cold and no choke warmed up). 4.) Plan on replacing your rings, it's a meager price to pay for 2 stroke performance and simplicity. 5.) Transmission sliders (what the shift forks move to engage transmission gears) or gear cogs are infamous for breaking. 2nd is the worst, because 1st is mostly useless on a 500, and most people would dump the clutch in 2nd. 6.) Get V-force reeds or Boysen reeds; it'll give you much better throttle response for little $$. 7.) There's better carbs than the stock carb for a CR500, but it can get pricey. 8.) 2 strokes are not intended to be lugged like a 4 stroke. Stay in the powerband, rev it, and hang on. If you lug the bike, you're going to just foul your plugs and not get the riding experience the manufacturers designed the bike to do. 9.)The bike looks thrashed, the swingarm bushings will most likely be trashed as well as the front tire bearings. 10.) Get fork protectors: it'll keep the forks protected from moisture, rusting, and pitting and keep the fork seals working better for a longer time. 11.) Purchase the latest "Motorcross and Off-road Performance Handbook" by Eric Gorr: it has a ton of tech tips and articles as well as what specific plague MX bikes from 80-500cc engines and most popular MX manufacturers (Honda, Kawasaki, Suzuki, etc.). DM me or contact me, and I'll provide whatever assistance I can over the phone, via email, or in person (I'm not too far away from you on the Atlantic seaboard). Lastly, if you'd like, I can bring my KX500 by and we can do some riding (you're welcome to ride the KX500 which has a brutal punch in the balls and demands to be noticed when it gets on the powerband).
And to sweeten the pot: I'll bring my 78 Kawasaki H2 750 Streetbike "Widowmaker" with the KX500 to your shop.
I knew I forgot something: you clutch basket fingers are grooved. This will cause the clutches not to release properly, making the clutch both prematurely "grabby" when starting from a stop and less likely to release as fast as desired when the SHTF moment that you want the clutch to work best. Check the clutch inner hub for grooving as well. The needle bearing on your clutch shaft is silver due to the aluminum powder going into the bearing. Replace it unless you want that bearing to seize on the clutch shaft, wipe out your clutch, and won't disengage (most likely at high RPM and about when you'd want the clutch to release when the SHTF moment. If you want a more durable clutch, get a Hinson clutch basket and components. You can also get a lockup clutch (used on the Yamaha Banshees) which will apply the full clutch force when the clutch is fully engaged).
The fuel spitting out the carburetor is most likely worn intake reeds. The two stroke uses pressure pulses from the exhaust to scavenge the cylinder which is supposed to be stopped by the reeds. And you really should have the airbox and boot to the carb as well.
The JB Weld turns blue when exposed to the green coolant.
An MX bike is designed to turn fast on dime and give 9 cents change. This makes them prone to a bad headshake at high speed.
Congratulations on putting the fork protectors on it and adjusting the jets.
Once you get accustomed to the powerband, you can keep the front wheel about 6-8" off the ground and steer the bike "moderately" like a unicycle on an open field.
I think you guys drained a bucket of liquid clutch plates out in that oil
That is my thinking too
Really enjoyed this video, brings back some good memories. Still have my 90 model 250 but it’s been a lotta years since I owned a 500. Been right at 30 years since I worked for the local Honda dealer, I was always the guy who had to test ride these after we repaired em for a customer. The other mechanic from back then still works there and a good buddy of mine, he’s not as terrified of them as he used to be. He’s only 5’6” and hasn’t had another growing spurt yet, lol. The 125 was more his size in the R model 2 smokers.
Most of the 2 stroke stuff I had been tasked with fixing had been usually looked as if a blind chimpanzee had been turning wrenches on it when they arrived which is commonly the case. Usually had the air boxes drilled and 8 out of 10 wouldn’t take the time to add screens to the holes afterwards or jet them up. Adding the air box back to your bike will undoubtedly help with your idling and midrange. While you’re into it this far run another compression test after replacing your crank seal to get a better idea of what you’re dealing with for cylinder and piston. I know that I’ve been into more than a few over the years that they’ve tried to do port work on themselves and ended up running the sleeves. After that they either had to buy another cylinder or we’d have to replace the sleeve in their cylinder, then you’re left with an inefficient port that puddles fuel. If you guys have a bore scope it wouldn’t hurt to look in the cylinder to see what you’re working with for wear and timing in your stroke as far as when your piston passes the intake and exhaust for the timing. I’m not positive that’s any of the problem you all are dealing with but I know for a fact that incorrect port timing makes them hard to start and really kills the power on the two strokes. Hopefully this’ll give you guys some ideas of where to start looking for solutions to what you’re dealing with. Good luck with the bike and hope it all works out for you.
John looks like a ten year old trying to start that bike 😂😂
When Charles said he's gonna put the muffler back together without the packing I was like "no no no no no", I could just feel my eats starting to bleed knowing how lound it will be... ya should know, remember the 670 skidoo snowmobile engine how stupid loud that was lol.... then a few minutes later the honda started and YEP its loud lol
You said left and right. I'm assuming you saw an L and R which could and probably stands for lean and rich.
You are correct...
We had one of those when we were kids my brother was a big guy when he was 18 years old he had that exact 1985 CR500 but it was complete withe gold rims, it was a complete bike. It was hard to get it to start up but that thing was a monster it was really hard to crank up because it had so much compression but you put the boot on and crank and cranking once that thing came to life it was a monster 1985 CR500 was a total Beast
If you can't start it don't ride it 💪
3rd gear takeoffs were standard and no big deal in the 80;s & 90's on the CR500. I amongst probably thousands more just knew that whoever was pulling the higher gear was probably going to win the race to the next turn. I also remember using copper clutch plates to transfer the heat out of the clutch, too. Properly running 500 two strokes had the low-mid range grunt to roost out of the gate in 3rd gear. 1st & 2nd gears only slowed you down in an mx race. People are so afraid of those bikes now, but actually if you rode with a clear head, in your limits, they were very forgiving and could pull you out of a bind. It was all in the clutch. Need more drive, feed her more clutch. They were fun. My stock '86 with pro circuit pipe & jetting, started easy, ran smooth and pulled 3rd & 4th gear speed wheelies with no problem. Just make sure the bars are turned to the left a bit when you start em, or else they could put a gash in your knee when it decides to buck. Haha We started them barefoot though. No big deal. Just kick it all the way through. Fun times.
Hi cars and cameras I want to let you know that I am 13 years old you have have inspired me to be a mechanic and be confident Thankyou for everything you are a great teacher I have learned a lot of things I prefer cars and cameras than vice grip garage because you guys are funny ,Thank you guys so much ❤
I used to have a 1985 kx500. It was also a PITA to start. It was mostly clapped out as well. It had 2 states of running, either it wouldn't start, or it tried to kill you every moment it was running. I miss that bike 😥
Two smokers can last as long as any other bike, you just have to know how to take care of them (In response to the statement they only last x hours). Ride them enough to keep the seals wet, rings from sticking, carbs clean, de-coke the pipes and use only the best premix; my preferred blend Golden Spectro mixed with Blendzall/real castor oil. I have owned many two stroke street and dirt bikes (first street RD400, Dirt PE400), and love them above all other engine types...SMOKERS forever! Great jobs boys..and yes the CR500 can be a hand full.
Man it’s running. And it’s a cr500. I couldn’t live with myself without checking the top end and the bottom end play and the reeds.
'DIRT BIKE FAB' did an episode describing the Right way to start the CR500 while he was rebuilding Paul from 'Fab Rats' bike.Couple motor tips in that for you too viewers.Kevin did a series on the rebuilding,and most of the tips will work on 2-strokes of all sizes.
i had a 91 for 25 years it was like new . was all ways a little hard start cold . got to old to ride it so i put it on ebay .the guy that won the bid was Henry Wiles tt racing champ . he had soft shoes on and hop on it to start it and i said man dont get hurt starting that thing.he gave me a look and said did you forget who your talking to and 2 kicks and he was gone. he had just won the peoria tt a record 14 times very great guy.
One of the best-looking dirt bikes ever I recon (Mind you I'm in my 50s so I don't expect everyone to agree)
Good to see the leg is bouncing back. i felt that pain just watching. Still have dents in my chin from trying to kick start quads with tennis shoes on... Don't miss those days lol
I've rode 2 strokes all my life. they always need the factory filter housing to run properly. love you guys. hope this helps.
I went from a 125 4 stroke to a 380 2 smoke, and man what a game changer, been wanting a cr 500 in a nice new aluminum 450f frame, im just too poor and dumb to work on stuff.
Kool Video ... Just happen to come across this on you tube...Myself i have a 89, CR500, Mint Shape. My Honda dealership where i live, has been trying to get me to sell him my CR500. And you never know i might do a trade for a VTX1300, not sure yet ! ... I'm almost 67 now and i don't ride it, Yes it was put away the right way. Most powerful bike i have ever owned was a Honda XR650R uncorked with a stage 2 HRC Kit . Just a little quicker than the CR500. The CR500 would be almost at my back rim on the XR650R all the way threw the gears. The 89 - 91 are the most sought after CR500'S on the market. Anyone interested drop me a note , comes with lots of plastic and mods i have done with this CR500. Might as well let some one have joy riding this icon motorcycle. Note: Never raced was my fun bike '' enduro '' .. Sure had fun with it...Mint Shape as all my bikes are. ( 1982 Yamaha IT465 - 1976 Honda MR250 100% restored all NOS - 1989 Honda CR500 - 1977 Yamaha XT500 - 2003 Honda VTX 1800C - 1983 Honda CB1000C )
YOOO GUYS these bikes are meant to run with the stock air box, air filter, and packing in the exhaust putting these things on might make it run better. It may also need new piston rings and I noticed that the clutch basket had some pretty good grooves in it so y’all might want to replace it soon too. it’s awsome to see all the new parts you guys are throwing at this thing and so far y’all have been doing it justice for sure 👍
Turn the choke knob in or out to adjust the idle and check the Reeds for hard starting problems they need to be ceiling nice and tight replace with boyesen reeds
We had a dirt bike neighborhood when I grew up. In 85, I watched a 220lb guy take a new one off the truck, fire it up in shorts and waffle stompers. He hit fist gear and she came up so hard and fast when he planted his foot the bike came over on him and we saw his knee get almost 360 Degrees of rotation as the bike fell back on him with out the boot moving. He was in surgery for 6hrs. And took 2yrs until he walked again. Go easy boys. This is the the beast of all beasts. The guy who got the bike at discount broke his foot a month later w a kick back.
Please keep and improve this! It doesn´t get anymore homebrew than Y´all do, I love two strokes and this animal has earned a place in Your fleet. It might be old and clapped out but still has enough oompf to straight kill a guy(s leg). We should respect that.
Honda was going against Maico with this and Maico was the meanest cat around. We need to see this in context of the time.
I can't believe how many people don't know how to start a big bore dirt bike. First put into 2nd gear and rock bike back and forth with choke on it will draw fuel into cylinder second don't kick, jump lifting left foot off peg with all your weight on right foot and complete throw from top to bottom of starter travel. It will usually start 1st kick. Always worked with my yz465 and cr500
I had a 85 cr for years did a lot of desert riding and many memories ! Love that bike and miss it very much !
Absolutely love Issac's Advertising! Such a great sport with the comedy of sport shaving with Henson Razors!
I used to have one of these... Either an 85 or an 86. All I remember is it was the year Honda stopped upping the compression. The next year they went down because of the starting issues. (And the broken legs) the guy I got it from said the kicker folded up and kicked back through, THROUGH the sole of his motocross boot! Regardless yours starts way better than mine did. I put some lights on it and rode it on the street. (Melted it down twice) the last time I rode it I passed two buddy's that thought I was an idiot for riding it and had left me behind. They were doing 110 and I came smoking (literally) past them!
And fyi the aftermarket kicker was shorter to turn it over faster. You might want to look into something like that.
Hey if you like vintage Honda motorcycles etc then you are going to love our sponsor, waterbed thermostat kings, for all your bedding needs.
Love the video though and how thorough you are with explaining the parts as you are replacing them.
Awsome. I use to have a Honda 480 back in the days. It was a 1982 model.. Miss it some time. But nowadays i ride a 4 stroke enduro bike
I gotta say, these dirt bike videos excite the heck out of me, any 2 stroke dirt bike 80cc's and higher yknow its gonna be a good vid. I cant wait for them to fine 3 dirt bike or a 125cc.
Man I feel for John. I've ALWAYS wanted a cr500, and at 5'9" 148 lbs, even with fairly decent leg muscle the couple I've ridden were a pain in the ass to start. Both were also clapped out heaps that you had to kick over and over.
Fill till u spill baby! My dune queen (77 whp 2003 yz450f) holds all of its oil in the downtube. It's so difficult to get the level right. Yeah man that old steel frame is with the 5 titanium valve head and 4 speed gearbox, I did a quaiffe billet connecting rod and a diamond billet piston and it's now a 505cc. Much stiffer Hinson clutch and basket, magura hydraulic conversion, 18 year old, $4700(back then i was sort of on flow for pro circuit so i got them for $700 which was just for the labor) pro circuit suspension I send back to them every year for a refresh, I ported and polished the head, full titanium pro circuit exhaust with a carbon can. I cannot remember exactly what silencer it is because my back wheel rubbed the logo off but it's the best you could have bought for horsepower back then. I was in the Marines so I just saved all my money on deployments and bought parts so when I got home I had just, TONS of parts for my '87 notch fox (foxbody mustang coupe, not the hatchback) and my yz. I own a 2023 yz250 2 stroke and a 2021 yz450 now.
Get a set of Vforce3 Reed valves there not to expensive and they will give you massive gains in throttle response and better fuel distribution going into the crankcase by far one of the best upgrades when it comes to 2 strokes.
love the old 500s ive still got my cr 500 but since ive owned it in last 8 years ive basically put my cr500 in Crf 450 frame and it looks awesome now love old 2 smokers and smell you cant beat it
My buddy has an 87 Cr 500 that is really hard to start unless it's warmed up. One year, we put a top end on it with new jug and head. We hoped that it would be easier to start, but no. He threw another 200 in parts with no luck. He finally decided to give up on kick starting it, and he just bump starts it when its cold. He will get another person to drive his golf kart, and he will hold on with his left arm to get up enough speed, then he drops it into second. It always starts right up when we bump start it but I've never seen it kick start when its cold.
I have a 1983 Honda V45 Magna, I ask it nicely to start every time, and to start running. So you aren't alone to asking an old Honda to start nicely for you.
one thing i suggest as i had this same issue. Check in the venturi of the carb just ahead of the slide. theirs two little ports in the bottom that allow the idle jet fuel to be drawn up into the carb. Had the same issue and thats all it was. blow through with some cleaner. If you look up a diagram of how the idle circuit works you'll see the holes im talking about.
This makes me miss my YZ 490...dang that thing was fun.
I was the only one nuts enough to hammer the crap outa that thing and once in Wyoming opened the throttle completely and let it rev out full speed. (Wyoming is really flat)
Just hauling ass out on the open prairies on nicely manicured dirt roads.
Felt like 120 MPH with how fast the landscape was whizzing by even in the distance.
A CR500 would be even better, I heard they tuned them down after 1986? due to how many people were getting hurt with all the power.
Hang on and go that way. Don't crash. Was the advice I got at 15 years old. Back in 1986. Just ride it
Isaac, you definitely had a Ricky Bobby vibe on that sponsor piece.....LOL!
The gray transmission oil is a direct indicator of a bad crank seal. It would be more of a white color if there was coolant in there. Also mix the oil and gas at 32-1 or 4 oz of quality oil to one gallon of gas. You usually increase or go up in jet size for a aftermarket pipe. If it had upgraded reeds those usually require smaller jets. So if you do them both together you’ll have to play with the jetting.
as a young man i had one of these beasts in the late 80s and never could really control it i felt as if it controlled me
Good, for some reason the zoom is stuck and your full frame right now, perfect. Love it
in 1985 i was 16 and my 19 year old cousin bought a CR500 new, we thought the 250cc jump from a 125 was awesome, the jump from a 250 to a 500cc was scary.. lol had a lor of fun riding dirt bike in southern California.
i think ike raging at the bike while trying to start it is one of the most relatable things ive ever seen. Great video hope you guys make more bike vids
I used to have a husqvarna 1986 motocross CR500 2 stroke (very rare now) if you think the Honda 500 was a hand full you ought to try the Husqvarna CR500 it has the kick starter on the left hand side of the engine just to make it even more of a challange to start..you could lift the front wheel in 1st,2nd,and 3rd with just the throttle no slipping the clutch this thing was an animal.
Wow, I remember when the 500 came out! It was untouchable by anything out there. I remember i tried to start one and almost broke my leg. Even trying to push starting it was a bitch. Thank you for the memory of the pain. Ray
I have a lot of experience with big bore two strokes and two strokes in general. First off. The milky oil out of the transmission isn’t milky. more than likely it had been a while since the last service and that is clutch friction material (very common). Secondly I would pull the reeds out and check to see if they are sealing off completely. You should not be able to see light when looking through the intake tube towards the reed petals. A 2 stroke should never spit fuel out if the carb. That can be a definitive cause of a rich jetting issue. As air goes into the carb it draws fuel then gets pushed back out because of bad reeds and draws more fuel. Then Gets sucked back in again drawing more fuel. Third I would highly recommend repacking the exhaust. 2 strokes rely on back pressure to have bottom end power. Also an air leak is the best thing you could have done for an old 2 stroke that has been sitting. air leaks are a very common cause of 2 stroke failure. You guys are on the right track to having a great bike.
Hey mate Liam from Australia, that’s starts completely normal. If u watch back through the video wen u kick it your not getting a full kick in it all the way down to the peg an also
As many other people have said ur not starting it properly. U have to put it in 4th gear an rock it back and forth on the ground for about 10 seconds then 3 3 slow kicks get it at the hardest point of the kick start an absolute jump on it, an I mean wen ur left leg is on the bike start take all your wait off the stand an throw it all into
The one leg that’s kicking u will start it first go every time
The inside of pillows the hollow fill. Works perfect for packing better than the original stuff.😮😊
I had a chance to ride a friends built '86 CR500R, Keep in mind I raced a 9 second busa for five years that I did not find very scary, but a built fresh engine on a CR500r is penty scary. I wish you guys all the luck in the world with that thing, and be cautous or it will bite you.
Hey Brother, I own a CR500, KX500, LT500 (Quadzilla), CR480, YZ465, RM465. My best friend also has a KX500. I start all these bikes, so my point is...I kinda know how to do it. First the 85 CR500 is notorious for being hard to start, I think it's because it has a small flywheel, and a high mounted kicker. So you guys know about leaning it over, this is because the choke is not very effective on a 500, because it doesn't spin the motor over very fast when kicking. So leaning it over spills fuel into the carb throat (a super choke). Now you need to draw the fuel into the chamber, this takes "sissy kicks". Slowly push the kicker all the way down, choke on throttle off, don't kick it unless you just want to get tired, push down with foot. Sissy kick until it goes phew out the muffler. Most likely that will be 7 or 8 sissy's. If it went phew out the muffler on sissy number 7, that tells you, your bike (the way it is jetted) wants to start on #7. So next time, sissy kick it 6 times, then a full hard kick from top to bottom, usually with throttle off, and it should start. I can usually cold start any of my bikes in 1 or 2 kicks. Your bike smokes a lot when running, usually an indication that too rich pilot jet or air screw (unless you went way overboard with premix oil). The airscrew is fine tuning for the pilot jet, so use it to tell you if you need to change the pilot. Start and warm/ride the bike, then stop, turn idle speed up a little, and turn air screw in or out until you get best idle. Engine should rev quick to 1/4 throttle, and drop back to idle almost as quick, if it hangs, turn screw in a little to richen. This will make it easiest to start. Your carb probably calls for 1.5 turns out (per manual). If it is ...say 3 turns out, you are adding more air to the idle mix...because the pilot jet is too big, compensating with air screw.
I believe the most enjoyable big two stroke in my experience was the 1970 yz400. Easy starting, low and long, fine handling and a torque monster.
Back in 1988 I was riding a yz465, then a yz 490, my friends had a cr500, we were at a sand drag and I took the 500cr for a ride after a few beers I hit a berm coming out the river and it made me hit wide open throttle I held on banging gears doing a long wheeley the crowd watched not knowing I was crapping myself.
I had an lt500r a handful of years ago, bored to a 560cc. I found it in my best interest to turn the ignition off while setting TDC. Turn on the ignition and kick. I was barely pressing it once and it fired, the kick start went down all the way and came back up so hard it literally took a small chunk out of my tennis shoe.
I learned the cheap is expensive lesson with my 05 crf450x as well with similer issues and have spent close to half of what i bought it for ,into it again and its still not runing 100%.Though im getting closer it is really frustrating making supposedly the right changes and it either still not wanting to run or just getting worse. Wish you guys luck on getting it to run correctly so you can enjoy it a lot since big dirtbikes are a lot of fun
Good work.That bike's an animal and you guys will have fun with it.I'd replace the clutch/water pump housing though.
from 84 to 89 honda 2 and 4 strokes was some of the most cold natured bikes i ever seen
It could be aluminum from the clutch basket and clutch pack , these engines use qt the most a quart of oil so ut gets dirty quick hinse the reason it needs changed after every riding session
