is it just me, it seems my bike does not make any valve noise at all, i was listening to my friends gsxr750 the other day and his valves were down right loud. and my engine had no valve noise, is there any thing wrong if my bike does not make that noise, it seems to be so common. 2004 W/ 4300 mi. i run 93 or 94 octain pump gas all the time and i have never ran a can of injector cleaner through it yet.
