05 CBR 1KRR rattling noise, need some advice
I bought bike used, it has 18k miles on it. I don't know if this sound has always been there or what, but its driving me crazy. I know these bikes makes nosies and what not, but this noise does not sound right at all. Bike starts up fine and idles fine. rattle comes on at 4k rpm and up. kinda vibrates the bike too and I can feel it in my handle bars. Sound is there in neutral and when in gear, clutch in or out same noise. Sounds like its coming from the clutch or transmission. I have taken the cover out and inspect the gears and basket in there. I did not find any abnormal wear or broken parts. Removed clutch plates and hand spun the inner clutch hub back and fourth. It spins freely, but does make a slight clinking noise when I spin it back and fourth quickly. Primary gear shows no sign of wear. Gears shifts up and down, no pop outs, but is very clunky and abrupt. other then that she rides normal and I do not notice any loss of power. The rattling sound and vibration is taking away the enjoyment of mid range fun of this Bike. I have done some clutch up wheelies here and there,but I like riding Hills and would not want something to break while I'm leaned over. Any input would be appreciated.
