I'm replacing the clutch basket damper rubber (which are rock hard and worn out) by making some teflon replacements.
This is an experiment and I have no idea how long it will last.

I replaced the clutch basket bushings in my 1981 Kawasaki 305 using a similar idea. Instead of Teflon i used a liquid polyurethane and poured the bushing pockets full. After it sets up it's really tough yet flexible and works great. I posted the whole process in the Facebook KZ305 owners group about 2 years ago. The Teflon seems a great option too.
Can I use HDPE?
@@betheanonymous I would not. It seems that hdpe has good heat and chemical resistance in static applications, but is subject to stress cracking.
Excellent idea and nice machining tips 😉
Hi I’ve an 1989 Yamaha 2stroke motorcycle and there is a sound of play in the clutch bell.
My clutch basket is almost new, Should I replace the rubber bushes in the bell or should I also change the clutch basket too
I would try replacing the rubber bushes first, if you can buy them.
Great job I watched you perform there was just wondering why no pic tite was used to keep new screws from coming back out was all...nice using Teflon wut right tools u had to create them ... outstanding everyone doesn't have that tool to make clutch basket dampers ...Honda doesn't sell them individually..I suppose they want you to buy entire brand new clutch basket 😁 lol
I'm curious how many klms on your bike. I own an mt09 with noisy clutch basket and I'm thinking my problem is similar to yours. cheers.
The bike has done about 50,00km, but I think the clutch was like this for a few years. Seems to be quite a common problem
For mt09 is available to buy damper!
Boa noite amigo sou do Brasil ficou quanto tempo a minha é uma MT09 tá com este mesmo problema? Aprovou ou não
Do you know if the rubbers are still available. I saw a guy selling them (in 2 sizes) on eBay a few weeks ago but the listing has now disappeared
May I ask why you didn't add any loc tite to those new screws you used in place of the drilled out rivet holes? So they wouldn't back themselves out under load as bike engine vibrates when running ?
Are these CB400F clutch damper rubbers still available? I saw your listing on eBay a few weeks ago for 2 sizes but unfortunately it disappeared before I could order them
Will the play lead to noise when idle?
It will make a knocking noise or rattle at idle
does this problem cause irritating sound when engine breaking? I recently got this issue on my mt 15
So did the teflon work ? or did it crack like a plastic? PU is not so good due to oil
I've only done 300 miles on them so far, so cant really tell yet. I think Viton ones would be a better solution, but they're expensive to get made.
@@maxfh768 what if you were to stamp or cut them from a sheet of viton the correct thickness?
Any update on the teflon clutch cush's? It certainly looked a good job well done. Be interested to know about this. I will have to replace mine on a 750 dohc too
Ive done about 1000 miles on these, but the clutch rattle is starting to come back, so i think the teflon ones are getting deformed. Ill be having a look at them next month. Thanks for watching.
@@maxfh768 have you had that look? Thanks for the video
@@maxfh768 how it is looking right now? Can you put update video?
Finally got round to having a look and they've worn a bit, so i made some viton ones instead ruclips.net/video/6wG73rUkYMs/видео.html
g,day Max. can you reply back and let me know the dimensions for machining and drilling. I'm not a machinist but do have a small hobby lathe, no milling machine and a 1975 CB400 4 with no clutch. I am hoping I can use a drill press to slot out. Regards Eddie. Western Australia
Hi Eddie, i can send you the drawings for the rubbers, you can email me at amx92@yahoo.com. I think you might have trouble making the slot in pillar drill, im planning on making another batch in early january, if you need some.
Hi eddie, ive made a batch of both types of the clutch rubbers now. They're on ebay www.ebay.co.uk/itm/156005488052
G,day Max, yes another guy with a CB400 4 clutch basket damper issue's. Can you tell me where did you source your Viton cord and what size. Would you be prepare to share your machining details. Also how long did your Teflon dampers last, time and mileage? might consider using Teflon if I can't source Viton here in Western Australia.
Regards

Thanks, those worn clutch baskets re really annoying. I got the viton sheet from a company called coruba, id be happy to share all the dimensions and the jig 3d print files if you want to get some made. The teflon ones only lasted about 1000 miles before they started wearing unfotunately
What would be the symptoms the motorcycle would show for bad rubber damper? Thank you
For mine it was just a lot of knocking noise coming from around the clutch area.
Thanks
how much to make me some for a 78 kawasaki kz650
What sort of noise did it make on the bike? I'm pretty sure my mt-09 has this issue, thanks
There was a lot of knocking noise coming from the clutch area, but it got a lot quieter when I pulled the clutch lever.
What could happen to a bike if this condition of clutch busket remains same I mean un repair ?
This one has been like it for years, so its probably ok, just makes a lot of noise
I recently repair this coz my bike jumps on 1st gear engage
It will destroy your transmission gear, bearring, The clutch damper absorb the combustion intermittent shock load
olmaz👎
