A lot of people including myself just have a fear of really ripping into things, especially smaller parts but with technology including TH-cam and just making video documents of yourself tearing it apart, it's something we can all work on and get more confident in doing lol
I usually pass on the famous ( just needs carb cleaned) on the sales ad, but I think I need to take a chance and tear into one. But I feel the same way
Don't play with the throttle when kicking an FCR carb bike. The accelerator pump shoots fuel in and can flood it out pretty easily. Here's a trick to get them to start. With the fuel on and the bike off, open the throttle wide open 3 times fast. This will prime the intake with fuel. Then choke it and kick without touching the throttle at all. If it still doesn't start then barely crack the throttle open 1/16 inch and HOLD it open like that with your thumb on the throttle tube housing while kicking. Holding it open a tiny bit like that also helps with hard hot starts too. Works with all FCR carbs 450, 250, 150 etc. Great vid. Hope this helps someone
I had the same exact problem on my Wr 450 and it bogged out then stopped starting. My grandpa told me to grab a tooth brush and toothpaste and clean the needle valve, jets and other brass. Put it back to together and it fired right up.
Rebuilt a Honda 450 this past summer & got in a hurry & f’d up the bottom oil ring on the piston. It still ran but would not stop smoking. I tried adjusting the carb but it was indeed the oil ring. Had to replace the cylinder again cuz the oil ring damaged the cylinder wall. Was an expensive mistake but I finally got it back together with a Wiseco 11.5:1 piston & no smoke. Runs great now. Good job on fixing the carb
I thought the chain was loose, then I remembered the sound my bike made just before my kick starter fell off. I knew that sound immediately. Glad you found it. Great job on the bike!!!!

Completely different bikes 😂😂😂 Ricky had a full factory race bike Completely different engine the frame and subframe will be slightly different and so would obviously the suspension and swingarm
it would be fun to watch you rebuild that rear shock on it instead of just buying a new one. they are really easy to do. I don't think a lot of people realize how easy it is.
Just remember that once your ready to empty the oil out have a 5gal bucket to stick the shock in cause once you start compressing it it'll shoot oil all over the place, and as previously mentioned you can get wet in a hurry.😮
I've done my 2000 drz400e rear shock. It was actually simpler than the forks waaaay less parts in there. Basically comes apart with a flat head screwdriver, hammer, and an adjustable wrench. Of course you need a lossless Schrader valve filler thing, a regulator, and a tank of nitrogen to charge it when you're all done.
Glad you popped up in my recommended feed! This was a lot of fun to watch because I went through this exact process with my 2005 CRF250X, which uses a near identical carb. It sat for years and everything was gummed up. I wanted to increase my chances of only needing to remove the carb once, so I replaced EVERYTHING in and around the carburator(new jets, diaphram, fuel lines, and even an upgraded to a dual spray venturi), and it worked! Was a super rewarding experience. If I had to guess why the diaphram on your yamaha was disintegrating, the previous owner probably soaked the entire carb in Chem-Dip(or equivalent) without removing that section of the carb. Chem-Dip + Rubber = no bueno
Adding to my earlier tongue in cheek comment, the was a superb video. This is exactly what youtube is about. Skilled people sharing their knowledge and expertise. I really enjoyed this. Thank you for taking the time to do this.
just randomly came across this video - the 450 caught my eye. I used to roll an '08 450. What a torque monster is was. But it was just physically too big for me - on paper it was supposed to be like 15 lbs heavier, but it was more. I thought it was going to be the hot start button - always seemed finicky on mine. Great job diagnosing and getting it up and going, cheers mate
Guaranteed that the previous owner used carburetor cleaner to clear passages with the accelerator pump still installed. That is what destroyed the diaphragm and orings.
@@104ducati ethanol is definitely a killer of rubber parts, I agree, not to mention the green crap it’ll grow in a fuel bowl in such a short amount of time
I am nowhere near the Bike Mechanic you have proven your own self to be, but if the guy refreshed the cylinder and never got it running then you are now breaking it in and the rings have to seat. Once broken in I would bet your smoke issue will clear right up. Great channel, great content and you are one great mechanic (self-taught or well trained, either way), Keep up the good work!
I know what you mean, I know nothing about bikes though but have fixed many a lawnmower carb, watching this video thinking even I could have fixed it 😀
Literally even a knobhead would've tried to kick it over, taken out the carb, seen its dry and bought a brand new one for 50$. He looked everywhere but the actual carb
I don’t feel sorry for him at all. He failed the basic test of being a bike owner, he wasn’t curious enough to ask the right questions, such as: How does a carburettor work? And failed to go through the simple check list. In this day and age, even if you have no manual, a basic Google search could easily turn up multiple forum threads and likely a few TH-cam videos. The internet is a rich resource. Zero excuse for not fixing that bike.
I just had a similar situation this week. My daughter bought a used Yamaha 125 atv for her son. The guy who sold it to her said that he bought it from someone and had been trying for 2 years to get it to run. He put 2 carburetors on it, a new coil and a new cdi box on it. She brought it to me and I ran a compression check on it and was really low. The spark plug showed no oil burning which was odd. Spark was good, fuel was good just low compression. Checked the valves and they were bad out of adjustment. Got them set right and the bike cranked right up. Adjusted the carb and this thing purrs like a kitten. Lesson here: Some people need to learn when they don't have the right skills to work on certain things and would save themselves a whole lot of money to take it to someone who does.
Nice job tracking down that excelerator pump issue. Time to invest in an exhaust fan for the cold weather when your doors are closed, might guard against health issues 20 or 30 years down the road.
Joe, I really like your smooth mechanic style. Your explanations and calm voice allow the Viewer to gain confidence that he/she too could rebuild this carb. Years ago I read in MCN that a JIS screwdriver should be the only screwdriver choice for anyone working on a Japanese bike. A true JIS screwdriver will almost never "cam-out" of a cross-head screw on any moto machine from Japan.
For safety reasons an MX competition machine should not idle when the throttle is closed. The accelerator diaphragm would have been the most obvious cause of non starting. The rubber compound of the older diaphragms can deteriorate rapidly when modern ethanol based fuels are used.
If you notice blue smoke during acceleration or on deceleration, check your engine oil level. If it is low, then you need to replace your piston rings and inspect the cylinder walls for any damage or blemishes. White smoke means coolant is finding its way into the combustion chamber, which can cause overheating.
I raced a 17 rmz450 on ice a few years back and loved it !!!

Where did you get starter roller? Have a XT500 Yamaha that has starting and running problems. It has knobby tires. My short 64 year old leg can't kick like it used to. I know how to use compression release. 😊
Video reminds of me of when i used to do lawn mooing business I knew my machine from A - Z to the point that i could disassemble and assemble it back when servicing.. it mostly had issues with carburetor overflow, too much fuel could fill up the cylinder and spark plug could just get wet not ignite the fuel. I think fuel flow is crucial..shouldn't be too much otherwise creates issues.

Joe your one of the best mechanics i have ever seen who works on dirtbikes and all sorts of stuff you are a blessing knowing how to fix things and you encourage me to do the same stay safe out there keep up the good work!
I've worked on a lot of motors over the years and don't even plan to work on any motorcycles in the near future but I really enjoy watching the problem solving and work ethic on this channel. Thanks 2vintage for taking the time to film and post these videos. It's so funny when you were riding in the field I thought it sounded like the kick starter was loose, I had the exact same thing happen to me on an RMX 250 30 years ago.
Great video as always mate 👍 your so chilled and mellow. No stress or drama. You just get the job done. Very therapeutic to watch. Keep up the good work . Repect from the uk 🇬🇧 👏
I’d be curious to to see what kind of messages he gets back seeing as he does it all on TH-cam. I do the same thing as him but obviously not on TH-cam and I get tons of threats and whatnot from people after I buy something fix it and it’s back up for sale the next day or two. They always want more money or they want it back and that it was a “mistake” that they sold it😂
I just recently repaired one that had similar symptoms to yours not starting and carb leaking. Turned out the guy had hooked the fuel line to the vent line and vice versa. Gas leaking everywhere. Let's see what you find out. Nice work. I thing though, blow out around the plugs no matter what condition the motor looks. One little rock or piece of rust can wreak havoc on a cylinder wall and rings. You work to hard for that. I do love your dedication. 👍
I may be wrong but after you added oil to the cyclinder, besides testing your compression, it’s also acting as a smoke down test. A couple times after you started it I noticed that smoke was immediately in front of the motor instead of all out the silencer like expected. I wonder if something is off with the exhaust gasket or its mating surface? Maybe causing that smoking and/or the backfiring!
What a lucky buy you managed on this one. I rode an old RM400 for a couple of years in the 1970's. Fast as hell in a straight line, but horrible on corners, whoops, etc. Miss that old dog. Nice carb work!!
The top rings on the piston look the same but one is a compression ring and one is a scraper ring. They have a different edge and are tempered different, because they do different jobs. If these are installed in the wrong place it will smoke. Just a thought.
Always good to watch somebody who knows what he is doing, making this bike work has been a great watch even though Im more of a two stroke lover having raced bikes back in the 80's
High concentration of ethanol fuel will do that to the rubber parts, especially on a dirt bike that doesn’t get run every day, Should always use Rec fuel, (no ethanol) Good stuff
Love your channel bro. I think I have almost watched every episode. It’s fun learning about fixing bikes and all. I got a 2015 kx450f which I never had a chance to ride yet. Haha. Keep up the good work Joe and can’t wait for the next vid
Excellent down to earth practical hands on videos, with great outcomes. Love your common sense systematic and relaxed approach in solving these problems.

Blessings and greetings from a Senior Citizen from Tasmania , Australia ( close to Antarctica) Keep up the good work.
I've found that letting silicone gasket maker dry while the parts are apart seals real nice. Most people use it like glue and it gushes out between the seams and into the motor. Silicone becomes Silica when it gets hot so it's not good for engines if it is floating around.😮
The Seller should have payed you to get it running instead of selling it but hey that not your problem you get lucky once in a while and get a good deal. Happy Holidays! P.S: There rear shock is toast lol
That fuel filter was installed backwards. Should be able to see any debris on the OUTside of the pleated filter. If the prior owner missed something as simple as that, makes you wonder how many other little things were missed. :(
spark or not, new plug or not... it's always good to take an ohm meter reading through the plug core and make sure its not corroded. non resister plugs read 0 ohm's. resister plugs should not read more than 5500 ohm's. or whatever the spec is for your rig. best to file the electrode to get good contact for an accurate reading.
Accelerator pump is an often overlooked carb rebuild part - most kits come with jets, gaskets, sometimes float, needles, but the pump is often overlooked and very rubbery, gas will disintegrate it especiallly if other seals fail, I've seen people buy Lectron carbs when in reality the old carb just needed a new choke or accelerator pump
This is amazing. I’m not surprised the guy couldn’t fix it himself, that carb was pretty advanced ? I wouldn’t have the experience to take that apart like you did and know exactly what I was doing. Great job, you are a great bike guy!👍🇬🇧
It's kind of like a normal carburetor with a few more things they're quite easy until you get to the mid body which sucks, be very careful with carburetor cleaner on fcr carbs there is rubber o rings inside that carb clean will harm you may not see the o-rings but they're in the mid body which is a tedious process to rebuild
Good job bro!! My kawi 450 did the same thing when I picked it up. Guy had smoking problems said he rebuilt the whole thing and after I rode it in a little bit it ran beautifully. Just a little smoke like yours. Great video bro. Keep them builds/fixes coming!
Back in the day when we raced these machines we bought a race kit, usually after every race session. Plug, sprocket, piston rings, diaphragm ( the perished seal in the carb) we also emptied the tank and ran new fuel.
Sounds a little lean on low and mid but an easy fix, wonder if the seller installed new valve seals and checked the guides? Hopefully as you stated the ring gaps aren't lined up😮 but I would lean towards valve seals and check that the oil drain ports on the head are free and not letting excessive oil pool up in the head. Best of luck hope it's an easy fix.🙂
no way brother, cant take the shaking and bouncing (i could for a bit but would pay in pain later) I see no point in just riding smooth surfaces . thanks for the encouragement
Thanks for making the video. I've been riding bikes for forty years and wrenching on them as well. What amazed me about this video is the deep dive into the carb. On top of the extra maintenance that these four stroke race bikes require over two stroke race bikes was the extra complexity of the carb. An EXTRA Jet for starting and a Hot Start Circuit, as well as the TPS must make them far more complex to keep running. At least you can flip up the rear subframe to get to the carb. Every Suzuki I've owned was a bastard to work on the carb... They must have very small hands in Hamamatsu...
I'm new to your channel and just wanted to say I enjoy watching you work your magic fixing stuff that other people can't and I'm learning so much from you dude. Love your work.
Man I wish I knew this stuff myself! Had a XL600V TransAlp for about seven months now, and ran with a drip-leak on the rear gasket for all this time. When I finally took it to the mechanic to switch it out, the bike decided to die (shut off completely) while riding after about an 40 minutes.. then more and more frequently. I rode it the next day, and the same story. This time I waited about five minutes before starting it up again, and was able to continue my ride home without any more shutdowns. The mechanic said there was a pipe in the radiator that is stuffed and does not allow for coolant to flow, although I never had the issue before the mechanic did anything to it, so I can't imagine it is related to the radiator.. unless the mechanic intentionally damaged it so I would come back for more business. Been trying to read up on the possible causes, so I can have some clue as to what the mechanic does to it in order to fix the issue, when I do choose to go back with the bike.. but yeah, I really would rather be able to fix it myself.
King of All MACHINES THIS GUY IS GREAT TO WATCH AND YOU WILL EITHER LEARN TO DO IT RIGHT OR WRONG AND FOR ME ID RATHER WATCH SOMEONE DO IT WRONG SO WE CAN LEARN TO DO IT RIGHT
I don't think anybody has sensed freedom until they kick start a dirtbike & take it on some skidoo trails... I'm going with carburetor cleaning... 6:00 YAY.. that exhaust gasket you might want to replace.. it is how my bike seized once on me... water & mud got in cylinder.. you call it a silencer, but I always heard it called a baffle... i used pink house insulation to re-wrap my 86 cr-80 with when I was 17 in the 90's.. put a new piston and braized the seat rails from triple riding friends out to Elgin Park.. Probably my favourite memories riding that dirtbike... first year for water cooling & front disc brakes..
It was burning the oil that the previous life left in the muffler. Repack. It will be less raspy too. The cover gasket was probably the original, 19 years old. Replace with OEM.
Hey that model you have there ,,04-05 also had a fault with the ignition timing slipping out on them it was a common fault which also made them hard to kick start you could crash start them but they would not start from the kicker ,,the breaker plate was not secured very well & would slip,, easy fix i think & some loctite sorts it so if it gets hard to start again check that out there was info on the net about it ..
At the end when he goes to ride I rebuild a bike that was blown up and the shifter spacer got lost on the dunes when the case broke, so after all that work when to put it in gear and nothin, had to take the whole right case off again and order a 1.29 spacer shim for the shifter linkage. Oh the joy of a surprise buy
I would love even a short follow-up on this if you have the time..I envy your skills! Watching and learning this was fun for me as an older boy (62). I thank you very much!
Seeing you work on carbs reminds me of how glad I am to have a fuel injected bike... No floats, jets, pilots, accelerator pumps, needle valves, etc. I love old school, but carbs are just not one of them.
I haven’t worked on a dirty bike in about 50+ years but I have enjoyed watching you fix the non start problems.

For safety reasons an MX competition machine should not idle when the throttle is closed. The accelerator diaphragm would have been the most obvious cause of non starting. The rubber compound of the older diaphragms can deteriorate rapidly when modern ethanol based fuels are used.

Thats a big statement right there😂
If you notice blue smoke during acceleration or on deceleration, check your engine oil level. If it is low, then you need to replace your piston rings and inspect the cylinder walls for any damage or blemishes. White smoke means coolant is finding its way into the combustion chamber, which can cause overheating.
Blue smoke could also mean a bad head gasket, or bad valve seals, or a bad Crankshaftseal.
And in this case its probably the valve seals for not running in the last 4 years

19:49 A common problem when running E10 fuels is that it destroys rubber fuel lines and rubber internals in both cars and bikes.
Joe your one of the best mechanics i have ever seen who works on dirtbikes and all sorts of stuff you are a blessing knowing how to fix things and you encourage me to do the same stay safe out there keep up the good work!
Not even close to one of the best mechanics, totally overlooks basic things.
I've worked on a lot of motors over the years and don't even plan to work on any motorcycles in the near future but I really enjoy watching the problem solving and work ethic on this channel. Thanks 2vintage for taking the time to film and post these videos. It's so funny when you were riding in the field I thought it sounded like the kick starter was loose, I had the exact same thing happen to me on an RMX 250 30 years ago.
2Vinny was Fired-up for this one, must of been from his lack of Screen Time from the Previous Video. Merry Christmas and Happy New Year to all. 🎄🎁🐕🏍
That is one happy dog... His mom and dad must give him lots of love........
I was excited when it got started. I dont know why Im watching this since I don't own one but it was interesting to see you repair the issue
Joe you have some vehicles lying around you must have a small fortune in your collection mate love your content 👍
Valves dude. Running or not, trust me!! Your in there do it!!
Great video as always mate 👍 your so chilled and mellow. No stress or drama. You just get the job done. Very therapeutic to watch. Keep up the good work . Repect from the uk 🇬🇧 👏
I loved watching this because I bet like many other viewers we are in tune with your moves by 80-90%... No surprises. Its like we are doing it too.
Just curious to know if any of the past sellers contact you with frustration about how simple the fix has been?
Too bad so sad now frig right off.
I’d be curious to to see what kind of messages he gets back seeing as he does it all on TH-cam. I do the same thing as him but obviously not on TH-cam and I get tons of threats and whatnot from people after I buy something fix it and it’s back up for sale the next day or two. They always want more money or they want it back and that it was a “mistake” that they sold it😂
I just recently repaired one that had similar symptoms to yours not starting and carb leaking. Turned out the guy had hooked the fuel line to the vent line and vice versa. Gas leaking everywhere. Let's see what you find out. Nice work. I thing though, blow out around the plugs no matter what condition the motor looks. One little rock or piece of rust can wreak havoc on a cylinder wall and rings. You work to hard for that. I do love your dedication. 👍
I may be wrong but after you added oil to the cyclinder, besides testing your compression, it’s also acting as a smoke down test. A couple times after you started it I noticed that smoke was immediately in front of the motor instead of all out the silencer like expected. I wonder if something is off with the exhaust gasket or its mating surface? Maybe causing that smoking and/or the backfiring!
this
i forgot to add my crush washer and i was wondering what all the smoke and backfiring was lol
What a lucky buy you managed on this one. I rode an old RM400 for a couple of years in the 1970's. Fast as hell in a straight line, but horrible on corners, whoops, etc. Miss that old dog. Nice carb work!!
Holly crap, there's a lot to that carb.! At 20:00, that's probably from that crappy Ethanol fuel were stuck with!
@antimatter314scary
The top rings on the piston look the same but one is a compression ring and one is a scraper ring. They have a different edge and are tempered different, because they do different jobs. If these are installed in the wrong place it will smoke. Just a thought.
Sounds like she might need the valves shimmed too. Nice buy!!!
"She" doesn't need the valves shimmed. Were you watching when he measured the gaps?
@@ernieschatz3783 oh I’m sorry is the bike a they/them like you?
@@ernieschatz3783 maybe it was the cam chain rattling. Who knows
nope it was that kickstarter rattling its ass off@@Darkgrabba
Always good to watch somebody who knows what he is doing, making this bike work has been a great watch even though Im more of a two stroke lover having raced bikes back in the 80's
gonna need the rear shock rebuilt too, can tell its blown by the bounce when you were kicking it over
You can also tell by him saying the rear shock is toast at the beginning of the vid lol
@@samuelgersbach646 I must have missed that 😁
High concentration of ethanol fuel will do that to the rubber parts, especially on a dirt bike that doesn’t get run every day,
Should always use Rec fuel, (no ethanol)
Good stuff
Love your channel bro. I think I have almost watched every episode. It’s fun learning about fixing bikes and all. I got a 2015 kx450f which I never had a chance to ride yet. Haha. Keep up the good work Joe and can’t wait for the next vid
Excellent down to earth practical hands on videos, with great outcomes.
Love your common sense systematic and relaxed approach in solving these problems.
Learnt more about watching a few of your videos than from reading theoretical textbooks and has encouraged me to fix all my bike problems diy.
Blessings and greetings from a Senior Citizen from Tasmania , Australia ( close to Antarctica)
Keep up the good work.
Merry christmas- i cant believe the volume of videos that you are putting out. Awesome
I've found that letting silicone gasket maker dry while the parts are apart seals real nice. Most people use it like glue and it gushes out between the seams and into the motor. Silicone becomes Silica when it gets hot so it's not good for engines if it is floating around.😮
The Seller should have payed you to get it running instead of selling it but hey that not your problem you get lucky once in a while and get a good deal. Happy Holidays!
P.S: There rear shock is toast lol
Even when the dealership can't find out what's wrong. He can. Well done buddy.
That fuel filter was installed backwards. Should be able to see any debris on the OUTside of the pleated filter. If the prior owner missed something as simple as that, makes you wonder how many other little things were missed. :(
Pilot jet
plastics are cheaper@@JakeDemuss-90216
spark or not, new plug or not... it's always good to take an ohm meter reading through the plug core and make sure its not corroded. non resister plugs read 0 ohm's. resister plugs should not read more than 5500 ohm's. or whatever the spec is for your rig.
best to file the electrode to get good contact for an accurate reading.
Vinnie is the best bro... Gets me every time. Keep up the good work man.
Accelerator pump is an often overlooked carb rebuild part - most kits come with jets, gaskets, sometimes float, needles, but the pump is often overlooked and very rubbery, gas will disintegrate it especiallly if other seals fail, I've seen people buy Lectron carbs when in reality the old carb just needed a new choke or accelerator pump
This is amazing. I’m not surprised the guy couldn’t fix it himself, that carb was pretty advanced ? I wouldn’t have the experience to take that apart like you did and know exactly what I was doing. Great job, you are a great bike guy!👍🇬🇧
It's kind of like a normal carburetor with a few more things they're quite easy until you get to the mid body which sucks, be very careful with carburetor cleaner on fcr carbs there is rubber o rings inside that carb clean will harm you may not see the o-rings but they're in the mid body which is a tedious process to rebuild
you can buy a brand new carb for this for about $200, would have been the easiest/quickest way to fix it.
@@MrRidleyDog I’m sure he fixed it for a small fraction of that price. Not everyone has money to throw at things like that.
@@TheGreatest1974 I'm more talking about the original owner.
@@MrRidleyDog Klein fcr39mx is about $750 and the 41mx is about $800 more cost effective to have someone clean it
Good job bro!! My kawi 450 did the same thing when I picked it up. Guy had smoking problems said he rebuilt the whole thing and after I rode it in a little bit it ran beautifully. Just a little smoke like yours. Great video bro. Keep them builds/fixes coming!
I love watching how simple you make the repairs look.
Im wondering where do sell these bikes?
Back in the day when we raced these machines we bought a race kit, usually after every race session.
Plug, sprocket, piston rings, diaphragm ( the perished seal in the carb) we also emptied the tank and ran new fuel.
Sounds a little lean on low and mid but an easy fix, wonder if the seller installed new valve seals and checked the guides? Hopefully as you stated the ring gaps aren't lined up😮 but I would lean towards valve seals and check that the oil drain ports on the head are free and not letting excessive oil pool up in the head. Best of luck hope it's an easy fix.🙂
no way brother, cant take the shaking and bouncing (i could for a bit but would pay in pain later) I see no point in just riding smooth surfaces . thanks for the encouragement
Thanks for making the video. I've been riding bikes for forty years and wrenching on them as well.
What amazed me about this video is the deep dive into the carb.
On top of the extra maintenance that these four stroke race bikes require over two stroke race bikes was the extra complexity of the carb.
An EXTRA Jet for starting and a Hot Start Circuit, as well as the TPS must make them far more complex to keep running.
At least you can flip up the rear subframe to get to the carb.
Every Suzuki I've owned was a bastard to work on the carb...
They must have very small hands in Hamamatsu...
Now send that rear shock in for a rebuild😏
very easy to rebuild yourself
@@robertdelinsky7247 -- Where's your link to a shock rebuilld video?
@@JIMPETERSON-n7i go to "upallnight91" complete rearshock and fork rebuilds an much more🙂
Edit: forgot the d in and, oops 😮

I'm new to your channel and just wanted to say I enjoy watching you work your magic fixing stuff that other people can't and I'm learning so much from you dude. Love your work.
Not sure how much they cost, but have you considered using the Pig Mats under your carb takeaparts??
Man I wish I knew this stuff myself! Had a XL600V TransAlp for about seven months now, and ran with a drip-leak on the rear gasket for all this time. When I finally took it to the mechanic to switch it out, the bike decided to die (shut off completely) while riding after about an 40 minutes.. then more and more frequently. I rode it the next day, and the same story. This time I waited about five minutes before starting it up again, and was able to continue my ride home without any more shutdowns. The mechanic said there was a pipe in the radiator that is stuffed and does not allow for coolant to flow, although I never had the issue before the mechanic did anything to it, so I can't imagine it is related to the radiator.. unless the mechanic intentionally damaged it so I would come back for more business. Been trying to read up on the possible causes, so I can have some clue as to what the mechanic does to it in order to fix the issue, when I do choose to go back with the bike.. but yeah, I really would rather be able to fix it myself.
Like others in the comments saying the shock needs a rebuild, this one needs it pretty bad😂
And pretty easy to do on your own. He needs to venture into suspension next!
King of All MACHINES THIS GUY IS GREAT TO WATCH AND YOU WILL EITHER LEARN TO DO IT RIGHT OR WRONG AND FOR ME ID RATHER WATCH SOMEONE DO IT WRONG SO WE CAN LEARN TO DO IT RIGHT
Merry Christmas to you the wife and Vinnie 🎉
I don't think anybody has sensed freedom until they kick start a dirtbike & take it on some skidoo trails...
I'm going with carburetor cleaning... 6:00 YAY.. that exhaust gasket you might want to replace.. it is how my bike seized once on me... water & mud got in cylinder..
you call it a silencer, but I always heard it called a baffle... i used pink house insulation to re-wrap my 86 cr-80 with when I was 17 in the 90's.. put a new piston and braized the seat rails from triple riding friends out to Elgin Park.. Probably my favourite memories riding that dirtbike... first year for water cooling & front disc brakes..
Few secs in and it sounds like a headache 😅
Came out good on that one, Joe! I really thought it was going to be way worse. Well done man! Merry Christmas.
And that's the simple stuff right there that people don't understand if it ran before it'll run again. Some things just need to be cleaned real good
Classic Ethanol damage on the rubber diaphragm.
Especially if the things been sitting for four years
It was burning the oil that the previous life left in the muffler. Repack. It will be less raspy too. The cover gasket was probably the original, 19 years old. Replace with OEM.
You know when he says "lets kick this thing over a couple times" he's gonna kick it over about 50 times
and show you all the kicks
Love that you got Vinny Involved!! I still have NO IDEA how you put these back together properly! SOO many little and different parts
Looks like a lot of ethanol went thru that carb.
Right and yes
I hope the previous owner won't watch this.. you fixed it easily. Nice job
Bro spent half his life just kicking bikes over😂
Recon he would walk around in circles …..right leg massive / left leg weak as …
This was the 1st crosser I bought brand new had a Kx 250 before …started off with an TSX 125 Suzuki make amazing bikes
that motor does not sound good I think.
Sounds like metal just crashing together don’t it?
Joe, hit up a welding store,pick up a torch tip cleaner. Compair to a filler gage but wires, strong and great for poking holes
You can hear the Kickstart rattle as soon as you had it out to ride and see it rattling after you put it back on. Good vid.
Hey that model you have there ,,04-05 also had a fault with the ignition timing slipping out on them it was a common fault which also made them hard to kick start you could crash start them but they would not start from the kicker ,,the breaker plate was not secured very well & would slip,, easy fix i think & some loctite sorts it so if it gets hard to start again check that out there was info on the net about it ..
At the end when he goes to ride I rebuild a bike that was blown up and the shifter spacer got lost on the dunes when the case broke, so after all that work when to put it in gear and nothin, had to take the whole right case off again and order a 1.29 spacer shim for the shifter linkage. Oh the joy of a surprise buy
You know you're riding a Suzuki when it smokes and the kickstart falls off! Nothing abnormal with it now. Good as new!
I would love even a short follow-up on this if you have the time..I envy your skills! Watching and learning this was fun for me as an older boy (62). I thank you very much!
Seeing you work on carbs reminds me of how glad I am to have a fuel injected bike... No floats, jets, pilots, accelerator pumps, needle valves, etc. I love old school, but carbs are just not one of them.
