I had an rmx250 that did that. It was caused bu the fingers of the clutch basket being worn into a serrated pattern by the clutch plates. A quick rub with a file and all was peachy again.

yes, this, plus those are the symptoms of springs collapsed in the cush at the back of the clutch.

They serve the function of a Marcel spring - which is a cushion spring to soften engagement. I'd ditch them.
I leave them in the big, late model motors as they're hard on boxes - but a bucket is a different story.

I had to go to my copy of "Clutch and Flywheel Handbook" to get the name of the spring - bastard for making me think on a Sunday morning !!

Thanks Grumph. Sorry about that . Iv been on youtube trying to find info about them but in the small cbr bikes it's only talks about the 125 which don't have them

Check the inner basket too for grooves, outer most common and the cush springs can be checked/replaced with nolathene etc.

So you mean the chain was trying to climb off the side of the sprocket?
