Hi there,
New to motorcycle riding, i have 92 cbr f2, im getting a noise in the top end of the motor when i start up on cooler mornings, sort of like a knocking, after the bike is warm there is no more noise. any suggestions?

 

CCT (Cam chain tensioner) most likely or with luck, a shim (valve clearance) adjustment & a change of oil.

 

did an oil change, there was ALOT of fuel in the oil, put new oil in and everything seams okay. carbs were checked a few months ago ,not sure why i would be getting so much gas in to the oil.
