Why don’t u do anything pats 2005
Are you gonna fix the exhaust there is the heater hose on it or is it fine like that?
This video pissed me off!, bro I love to watch your videos and I always look forward to watching them but, trouble shooting skills are 💩 ,why not buy the right tools, or remove the engine and tear it down if you tear it down and everything is good what do you have to loose, a few gaskets or seals ? At least you kno everything is good or not and I know your subscribers wouldn't mind a detailed video of a engine tear down, and showing them how everything works and goes back together, teach these guys that are new at this or have the same issue how to solve the problem right way not half-ass everything.
@@2817485160 next video will be the tear down. I was trying to diagnose and see if it was something small before having to tear down the whole motor. I hope that makes sense.

To the 1% reading this god bless, stay safe and have a wonderful day (my dream is to become a famous moto vloger) Thanks❤️
Couple theories.. 1)if there was water all in the exhaust it could’ve mixed with exhaust soot and turned gray.. 2)head gasket... why it dies in gear is interesting to me. My kids pw80 is very finicky until its nice and warm.. good luck tho!! Look forward to the resolution! 🤙
Definitely needs full rebuild man but fortunately for a bike that size it's pretty inexpensive that's a perfect candidate for a full restore!!! Keep in mind when your like ugh I don't want to put that kind of money into it 2 stroke Honda's are a hot ticket item in the mx world right now for riders and collector's alike
Head gasket could be bad and letting gas and antifreeze mix up and go down the pipe which could be why that spark plug look so new
Nah
Joe you may want to check the slide in the carb. I’ve seen them wear a grove where the idle screw goes in the carb and the slide can get hung up on it and cause it to idle high. It sounds better but the idle is a little too high. Also sounds a little boggy at low rpm.
The throttle cable adjuster is just there to remove slack. Use the idle screw.
2 Vintage they probably tried to adjust the idle with the throttle cable it will make it rev up high then drop like that they need to use the idle screw on the carb to adjust the idle awsome job
ahh might be the problem on my 125 4 stroke dirt bike.
didnt think about that, it revs high goes down to almost stall or keep it in the revs even doh u let go. not that bad but sopmething i can check
Head seals inner o ring they dont run on antifreeze ive never seen one do that but my kids bike needed the top of the cylinder decked and new o rings because it was warped
9:13. Just throws that float 😂 good job joe Lol
You can check crank seals using a propane torch I did it on my sled found the problem it’ll rev to the moon if it gets a sniff of that gas
Once I got like a 1998 cr80 for $150 it just needed put together and it ran great
I usually push start a low cc bike when i'm not sure if it will start or not, it's way more effective than just kicking. Put it in like 3rd or 4th gear on a 6 gear transmission and it starts up pretty quick or just doesn't at all
You should take it apart and put new crank seals and gasket kit
last time i had seen oil like that in a pipe was my old rm 80 1992 when the head gasket started to blow and rings was worn :/
great video cant wait for part 3
hey a nice little trick i do i use that black rubber stretch tape and go around that intake boot a lot of times it works for a while but sooner or later it comes down to just get another boot them boots can look sealed but they are not so don't count it out because it needs replaced yo might check the reeds
Could one of the coolant passage ways be crack and leaking into the fire chamber? I have had a lot of 2 strokes and i know that the spark arrestor will build up with the excess 2 stroke oil over time. If coolant mixed with that i would imagin it would look grey and milky. If the leak is in th the top part of the fluid passage way it would get spit into the exhaust before it made it to the crank case oil.
That thing needs a top end rebuild. While your at it tear it down do a engine rebuild . Never seem gray paint come out of a pipe lol. But a total rebuild needs to be done. PERIOD
CRANK SEALS SHOT and WATER PUMP SEAL SHOT ooof
Easy fixes
Looks like a lil kid had fun stuffing anything that fits up the exhaust.. definitely head gasket and change float back to where it was and should be sweet. Would've blown headgasket from blocked pipe is my guess
Change the oil, best idea!!
You need to spray break clean around everything on that topend
You can also spray carb cleaner at the air intake to see if you have a leak, instead of tossing gas on a running engine, take care
The slide could have wear, and what was the clip position? Not sure about if you can replace cr80 main seals without splitting cases, kx80 you have to split. New main seals would be insurance.
Get a pair of cheap calipers to measure float height while blowing gently through the hose to measure proper height and see if needle and seat works. If you have kids, you know they shove crap into everything.
That pipe getting filled with oil is the center case seal buddy***
If its not an air leak get a new throttle cable or try adjusting the one you have
My old rm 80 done that,was a few things,gasket,and the rings were shot,after that it ran perfect for two months,but then the head went,but I had it checked when I done the gaskets,but was probly my fault,as I hammered the guts of the poor thing,but that’s how you drove the 80,s they was just fun,exp full throttle
Use the correct wrench come on you have people learn from you do it correctly
Looks like there where a few kids playing around with it.
Cr250 build was awesome, now we get more Honda content!
Why do you give it so much gas when trying to start it?
To Get gas in the carb in order to give it a better chance to start it
Hey man ive been watching your videos for the past couple of months and i love watching them, Keep up the good work man!
It needs mixture setting, it sounds flat as a fart
Had this same problem but I fixed it need to find that air leak
I always wanted a dirtbike
I would just use a radiator pressure tester to see where the water was going before I tore into it. You just pump it up and look for coolant, air bubbles, or if you can't see anything and the pressure decreases you know you've got a problem. Or take the radiator cap off and look for bubbles as it's idling. That spark plug being so clean it's gotta be a head gasket more than likely. The gear oil would be milky if it were the water pump seal
Looks like oil in pipe is coming from right side crank seal. That is the only possibility way to get gear oil in the combustion chamber remember this is a 2 stroke the transmission and crank case are completely separate unlike a 4 stroke. I would bet that is why it is running so smokey.
I totally agree. I bet it is that right side crank seal.
More than likely it's the crank seal on the clutch side sucking oil in from the transmission and it sat outside in the rain that's y it looks milky
Milky oil is usually water mixing in isn’t it? Maybe the head gasket is leaking?
You changed the float height and now its starved of fuel . Will idle but nit enough fuel fir main jet
Possibly the crank seal on water pump side is bad and case oil is getting into crankcase
nice job! one thing: the chain lub always made from the inside due to centrifugal movement.
Great video!! Let's get a tear down going 🙏
Stop running it like that. Your gonna lean it out and blow it up. Troubleshoot air leaks. Then put a new fuel filter on. If that doesn't work put a bigger pilot jet and main jet. Hope you can fix it and have fun with the old cr's
Yo I love your content keep it up I have been subbed since 70 k
Bro has 340k now 💀
What I am seeing is that classic milkshake of death coming out of the pipe. Somewhere, water is being introduced to the bottom or top end. What came our of your pipe is definately water mixed with oil.
love the vids i wish i could find the deals you find on Facebook market place here in Ontario Canada.
Yeah ikr, live in Ontario too but I feel like nothing comes up this cheap
@@yamahayz2505 check the minimum wage in America vs Canada , its all equal . that 400$ destroyed cr80 you can find for 800$ here in Canadian . Americans make way less per hour on average that's why their products seem so cheap to us , reality is its basically equal..
Canadians make way more on average and our products cost more . Americans make way less and the products cost way less over there .
@@godmangodman9453 That's not true. What's minimum wage in Canada? Plus cost of living factors into wages in each country. I can't find 400$ near me. Remember he lives in a rural area where bikes are alot more common than other parts of the US and Canada
Use a can of brake clean and spray it around the engine to help find leaks. Crank seal are probably bad. Fix that dent on the pipe. Fill it with just enough water and put it in the freezer
Please, please please stop twisting the throttle when starting a smoker with the choke on... you are adding toooo much fuel. just turn in the choke, no throttle and kick, she will fire
I had a blaster one that had dropped a piston skirt and redid top end and it would suck oil from clutch/crankcase it had cracked the inside of case is the issue I found after taking it back down
Check the carb once again it may be the float seat that has some junk
My 2004 Wr250 had the same problem they call it hanging idle. my cables were binding up and were dirty so I cleaned them re-installed them the best I could without twisting them too much and the problem was fixed.
The throttle could be sticking as well
Haha awesome. I take a guess of the guys kids posting stuff down the back box 😉
Yea probably sat in the back where the kids played.
Check to make sure the clip is on the needle jet for the carb slide. That'll make it run away crazy like that as well.
10th videoooooo baby lets go im on a roll right now
Joe, you can't "play" with float height. It's either wrong or right. There is no in between.
He thinks he can. Master mechanic
He's doing fine you just can't take short cuts. He's learned a lot over the years. He's much better now.
@@rigguyjt 🤣
@@mikelyons469 🤣🤣🤣🤣🤣🤣
@@mikelyons469 I'll say what I've said before. It's the ambition and push that he has that really counts. A lot of people his age are sitting on their balls waiting for someone to "give" them something and he is doing all this on his own, has reinvested his money over and over and has a new wife and house to show for it. Give him a little credit.
You should take the hole bike apart and fix everything and paint the frame and motor and everything make it look like new and the see how much money you could make off of it after you done doing that
Float is sticking shut ? maybe? It started right away after you adjusted the float higher. water in the exhaust pipe hope the o seals arent bad? See if it get water in the pipe again? If no water in the pipe its not leaking. If it was leaking wouldn't it foul the plug green? some kid probably put the stick in there and some water. little guys kids think they are working on motors when they fill the exhaust pipe with sticks and water guns and stuff.
Bad water pump seals are letting water into the gearbox and is getting sucked into the crankcase via bad crank seals.
It would not hurt to do a topend job on the bike I have a 2002 cr 80 it's faster than the 85 cc they make iitshard too put your hands on a decent looking cr 80 they are collection of people that want a cr 80 they are worth investing in they quick then any other 85c if there set up right they don't weight are not as much as other bikes I would put me a new wisco pro lite piston kit and go from there I have had a couple cr 80 rebuild it and you will be surprised of the power that a cr 80 puts out I want sell mine I put a brand new plastic kit on it and replace the top end with wisco pro lite piston kit with gaskets and everything needed to rebuild only 120 for the rebuild kit and check the head had mine replated cylinder and a new set cover put on it with a new set of boysen racing reeds and new tires front and back a set of dunlop mx 52 tires nice and only a hundred dollars for the pair luv the bike and I own 3 other 85cc dirt bikes but the cr 80 is faster you want regret putting the money in the bike it will wheelie like crazy a friend of mine had one like mine and sold it for 3000dollars I have been overed many times people want too buy it I'll pass like I told them it's not for sell and your bike would not cost that much too have it like you want it they don't make them anymore you will see how fast that small bike is when you do a topend job you will fall in love with the power it has good luck Mike Holden out of north Carolina said that
Maybe get a kawasaki kxf 250 they are great bikes i own one myself
Maybe a kfx 450 that would be awesome 👌
Come on buddy so obvious right side crank seal. Need to invest in a crank case leak down test kit or make your own. 2 strokes need to be air right inside
Try running it without the muffler and silencer.
Wow I've never seen a stick come out before what was they trying to make it quieter 😂
I’d say water made its way down the silencer, into the expansion chamber. Someone ran it wayyy too rich (oil) then probably leaned it against their house, under the gutter. (Milky)
Actually, I take that back. A 4yr old mechanic was trying to fix it. He stuffed everything in the driveway he could find down the silencer and then added water. He just wanted it to run, that’s all😂😂
Thats what happens when you hook the radiator system upto your exhuast!! I think exhaust systems are supposed to be air cooled instead of water cooled. Just an idea though!! :P
Is there oil in your radiator? It looks like coolant getting in your cylinder.
Crack seal gone bad behind clutch cover
Air and full mixture has to be just right. Not sure about the milky substance never seen that one befor . Nice job discovering them sticks in the pipe.
i would kill for a bike like this, a shame we dont get them this cheap here.
It almost sounds like it is starving for gas, not at idle, but when you put it in gear and it is under a load.
Definitely needs new seals. Guarantee the head gaskets blown the oil was too white to be just oil
Have to get me an old school ripper like that .....would be great for the cottage. Regular bike is a 2014 yz250f
Your muffler looks loose and that doesn't help with back pressure. Tighten the clamps and put rear mounting bolt on..
that motor needs the crank seal behind the waterpump replaced because its leaking
It might be because the magneto is a little loose. It messes up the idle and throttle response happened to my bike take the magneto off and check the keyway. Great content mate love watching your videos. 👍
I'll check that thanks!
Why havent you bought a leak down tester to eliminate or solve the problem.
Pipe is full of oil from being a two stroke, what came out was probably just rain that went down the muffler and sat in there mixing with the oil. ( the seat was wet after all )
The stick well that’s a mystery, maybe a “tool” someone was using to clean out carbon
Hahahahaha..... I just spit out my coffee reading that!!!!! Hahahaha.... You my friend are hilarious!!!!! 😂😂😂😂😂😂
If the oils milky it got water in the motor oil
I would try putting the right plug in. That plug is only for 82-84 cr80s
You should get one of those rubber wedding rings so you don't get your nice one dirty working on bikes
My 2016 kx100 kinda does the same thing too. When I cold start it, it revs really really high then when I ride it around it doesn't idle. Air leak?
And when I cleaned the carb it didn't do nothing and changing the idle stew doesn't help cause then when its warm I have to change it back
You should have know that joe it’s obvious it revs up high
floats too high man when you sit on it your flooding I find small bikes are very fussy how much gas is in bowl...look up spec and adjust so you can rule this out.....and guy before you probably oiled jug to help what he suspected (low compression) I would look deeper into carb before you tear into top end with 150 psi !
Head gasket or might be the carb sticking look at the gas cable.
With that much oil in the pipe you should take off the top end there is probably a bunch of it sitting under the piston in the crankcase, explains the bogging. Don't guess on the float height, set it to spec.
You should a xl 500 dual sport
Sound like a bag of Nails
Doesn't sound right at all sounds flat a Motocross bike is to sound sharp and responsive
This gives me flashbacks to an old blaster. I couldn't get it running for the life of me. Everything's was right, and I deleted the tors, but the damn thing just wouldn't start. I pulled off the pipe, and it turns out there was a mouse nest clogging it up! As soon as I put the pipe back on, it ran perfect.
It’s a roach. That’s how it’s possible
Why don’t u do anything pats 2005
day 7 on telling you to get a predator 500
I’m pretty sure you need crank bearings and crank seals
yea your correct. the left side seal being bad will make the idol trail off because of an air leak in the crank area and the right side seal being bad will cause clutch oil to leak in to the crank area. and burn off or just push in to the pipe if its too much to burn.
It looks really neglected they probably left it out side and rain water got in the exhaust. And try some permatex 82099 spray and seal for for the air boot when you spray it on it drys clear. I have used it for years it works awesome. Great video these bikes need to be saved.
Home Depot.... 4 bucks.... I always buy my rubber boots from them.... Thank me later.... Spread the word
often a good idea to measure float height and adjust to manufacturers spec 🤣
You are awesome sir... keep up these awesome videos. I appreciate them
Let it warm up when it’s cold 🤦♂️🤦♂️🤦♂️🤦♂️🤦♂️
Dude stop smackin yourself in the head.
All throttle cable?? May be to tight.
