Cb400f Clutch basket rubber cush drive

I made a post a while ago when I made some Teflon cutch basket rubbers. Since then I've been doing some experimenting with Viton to make a softer and probably more suitable set. I machined them out of 10mm Viton sheet (which is disgustingly expensive). Hopefully these will be a suitable replacements for the old ones which you cant buy anywhere. I think another user Vehmulski had some tooling made up to stamp the rubbers out, which would be a much better way to go when making a lot of them.

Also, one of the baskets I took apart was identical to the other 400 baskets, but had different cush rubbers ( a better design I think) and a very slightly different gear (1mm smaller holes for the rubbers). Just wondered if anyone knows anything about this, maybe from a cb350?

Very interesting Max, nice job as well. Pretty sure someone in South Africa tried something very similar but the rubber didn't stand up to the job. We'll have to see how the Viton lasts in use. Keep us informed, I'd like to open a 500/550 clutch basket one day and see how they are shaped.

Cheers Oddjob, I'm also pretty curious to see what's inside the other sohc4s clutches.
