It's the damper springs in the back of the clutch basket.
To stop it you need a new basket but it will wear the same eventually.
It's normal.

Been over 40C this week so I'll send you 20 degrees of heat if you can send me 20 degrees of cold

If you know a good welder or a machine shop you can change them out yourself (I've done it a couple of times). Both times I just shimmed springs that were in there. Greatly improved how smooth clutch was under hard launch.

Yep, not too difficult to shim them.

Those things must get loose quick cause my bike only had about 3K miles on it when I got it. Course it's done nothing but dragstrip duty since new. Can you buy those springs seperately? (just curious) Hey Bladeracer, ever find a head that will work on your engine? I have a head and valvecover for blackbird in transit as we speak. Gonna bolt that to blank case and start fitting it to my RR frame, can't wait for some results.

i broke a bolt puting the pressure plate my life really sucks lol i had them snug wtfff

i have some play on the clutch housing is that good or bad?
