Motorcycle Starter Clutch Rebuild How To

This video shows you how to rebuild a slipping motorcycle starter clutch. This is a very common item to wear out in these old bikes simply due to age but is unfortunately something that can keep your bike from starting. This will be a very similar process on your CB750s, CB900, GL1100, GL1200, CB550, GL650 and many more!

On this CX500 you can see that one spring was actually broken with another being compressed and worn. These two things keep the bike from starting. Note that I looked for a long time for any broken spring material and did not find any. It would have been very soft metal and not able to cause damage anyway.

I haven’t worked on bikes in years. I really appreciate these videos so when I do get a bike project I’ll be a bit ahead of the game. Thanks young man!

I'm curious as to where is the other piece of broken spring ended up at, did you find it?

Edit: Never mind I read the description and got my answer.

Honestly, I've never had enough guts to look in there fearing there might be some funny stories putting it back together. But I also wondered what sort of a mechanism is there that releases the flywheel so fast, precise and soft in a way. I knew there were these kegs but to think it's pretty much just a little spring pushing them to create friction is making me smile for some reason. I am no mechanic but it kind of makes me wonder how common this kind of a mechanism is among the petrol, diesel automotive world. Anyway, as always - a great video, focus on details and the format itself.

You don't want to have to change out the starter clutch on a Honda CBX engine, that job requires splitting the cases to do that, as all the hardware for the clutch & rollers is mounted on the jackshaft assembly. Barrel of fun to replace! If your CBX is apart, this is the time to inspect/replace those rollers & springs before crankcase assembly.
Great video, keep 'em coming!

Another excellent instructional video. I hope my CX500 won't need this soon. Engine was just out and back in...don't want to repeat that too soon.

[MartyG]

I love your teaching videos. I don't have a Honda, but love videos like these anyway

[grahamhider]

Have the same with my old Kawasaki 750. All best from England ❤

[richardkilb]

Love your work, good video.
I did the same job on my V Star, when you pull the flywheel it's difficult to hold it together, top tip, tuck/slide a rag behind the flywheel to prevent bits dropping into the crankcase.

My old cb450s had the 3 torque screws come loose. Heard about ut multiple times on the forums too. On that one you need to remove the crankshaft to get to is, since its between the crank bearing holders. That was such a blessing lol. Cleaned it out ultrasonicly and drowned the threads in green locktite.

BAM, engine drops and you laugh - jack goes out - haha! Once again your skills amaze me BJ. Even in your backyard tiny garage, I learn something everytime I watch one of your videos. Among the many informative, demonstrative, and well explained things in this video, my favorite is hearing that nonexistent torque wrech click click click!! 🤔💪🍻❤🤙

Very helpful, made me confident to pull the engine on my 85 Goldwing 1200, thank you!

[paulrooney]

Another super how to video, dude you are awesome! Glad I have 2 CXs so I can ride one and fix the other. Such high quality explanations and video work

[ujmrider]

I've done this job twice. Once on a 1983 CB1100f and once on a 1978 GL1000. The inline fours are definitely easier than a Goldwing because you don't have to pull the engine. I'm getting ready to do the job on my 1980 GL1100 now. It sounds like shaking a can full of rocks when I hit the button.

[johnhsedgwick]

Getting ready to open up the left side crankcase on my inline4, 1983 CB650, hoping the starter clutch sits outside and not buried. Seen some videos where folks drop the oil pan and access through the bottom.

[Badenhawk]

I need to do the proper mechanical seal fix this winter, so while I have the back cover off it seems like I might as well do this, since it seems like it's cheap and easy when everything is apart anyway.

[carlosa.acevedo]

Always love watching your vids. Always super detailed and very well explained. Btw, being from Puerto Rico, parts are usually a bit of a pain to come by. Do you have any go-to sites for oem pieces and very specific engine internal components? Much appreciated if you or anybody in the comment section could share some knowledge.

Btw keep on killin' it man 🍻

[Einherjar_]

Excellent work and explanation, thank you very much for sharing it!

[ronaldcooper]

The starter would spin during cold weather starts on my 07 Goldwing. I switched from synthetic oil to conventional oil and that fixed it.

[aaronspitler]

Good job enjoyed your video. That particular application seems like it could be maybe a little easier than some others idk I have an '86 cmx450c that has a problem with the starter clutch.

[busybodyblake]

great video thx and what kind of puller is that different than a harmonic balancer puller..also about the thrust washer what is its job thankyou!
