Hey guys, I have a question about my 1996 cbr 900rr. my bike when i start it up when its cold, there is a knocking noise in the clutch area and its pretty loud,but if i pull in on the clutch lever it seem to go away and it gets quiet. let the lever out again it goes back to knocking again. after the engine warms up you can barely here it.

Its annoying and embarrassing, is there something wrong with my clutch or what? I really need help with this. thanks!
