does your yzf make alot of noise around the top end??

my 400 seems tro make a lot of noise around the valve and cam area. its louder from the right side then it is from the left. everyone elses bike sounds like that??? i also installed a 450 cam not to long ago. does that need to be broken in, or do valve clearances need to be checked after some break in??

They are definetly noisy, but mine did quiet down some after adjusting the valves.

My 426 is a little on the noisy side...just the nature of the beast...that many moving parts is bound to make some noise.
