Hey, i have been noticing now that no bikes (that i can think of), or cars have gear driven cams anymore.. Seems to me that cam chains on a lot of jap bike engines are the weakest link (no pun intended heh heh), and everybody raves about the gear driven cams on the vfr750. I can certainly see why, fantastic noise, no maintainance, accurate cam timing (no stretch). So why no more? Cost, noise (tho its gorgeous), anyone got ideas??
