Evening all, I've come here after a long search and asking on Facebook hoping that you guys could help me out. '11 Fireblade, 36k. I've a rattle that seems to only appear when the bike is warm, between 2-4k rpm. I replaced the CCT with a brand new, genuine Honda one, thought it was sorted... until 200 miles later when i noticed it once again. It happens on acceleration and decel. Nothing on idle. I've no record of the last valve clearance check, but don't want to put it in the garage for hundreds of pounds to find out they're all within spec. No other odd behaviour than a lopey idle because of the yoshi pipe and O2 eliminator. Clutch very slightly noisy when lever isnt in, nothing out the ordinary. Hoping someone can help me! Cheers
