I'm new to the forum and have been looking over some of the mod threads, etc... Looks like a great place for info on our beloved Vmax. I now have a 2006 Vmax which is set up with the ususal mods from front to back. One mod that I haven't seen on this site is a true manual vboost. I unplugged the stock vboost system and unhooked the cable from servo motor to the vboost butterflies. Installed a turn grip style gear shifter (taking from a 21 speed bicycle) on the clutch side of the handle bars with the cable hooked directly to the vboost butterflies. Now you have vboost on demand, and you can vary the amount of vboost you want depending on conditions or mood. The beauty is that your hand never leaves the hand grip, just twist and go:surprise: In VBoost we Trust!!!
