R75/6 Clutch noise

[Andey]

I’m sure there’s another post on this, but I’m getting a noise in the transmission area which sounds like the clutch plates, that disappears when I pull the clutch in...

Seems like a common problem, but I couldn’t find any conclusions to the problem online...

Any thoughts?

Read Snowbum's article on transmissions...he has a section on rattles:

It's pretty normal if the noise disappears when the clutch is dis-engaged. It's a dry clutch setup and it's the small amount of play on the throw-out bearing assy. and thrust rod. In some cases, the felt on the thrust rod is missing. You could pull the rod to verify if the felt is still there.

I’ve just gotten back from a 15mile test ride, and the noise has almost disappeared, well it’s gotten back to it’s original dry clutch spinning noise...

Seems to be caused by mis balanced carbs... and I’ve managed to get them in a decent place... no rocking cylinders anymore... at all... I didn’t think it was possible to achieve such a smooth idle and midrange... it really is possible...! might post a reminder here to highlight how I got to that point...

Oh I have the correct parts in the transmission... pieced together the push rod, felt, bearings and washers myself, a mix of new and old parts which seemed to be in good condition... clutch seems to be engaging good, regretting I didn’t replace the whole clutch and not just the friction plate though...

Thanks for the reply though guys... all added up in finding the solution
