Personally i don't care for 6 speeds way over priced ($2000 plus) I have a 34 tooth transmission sprocket installed on my scooter and can still get the front wheel off the ground when the rear tire sticks!!!! At 80 mph I run a little under 3000 rpm and the motor is relatively quiet, good for listening to music. Now to go out on that limb, I would recommend if your tearin' it apart to replace the needle bearings with a brass bushing (i don't think your gonna find that bushing on a shelf somewhere though) but that's a recommendation for people who like to do hole-shots!!!!

Oh yeah! the stock clutch hub is a bit of a weak link also (I had to replace mine, tore the spline completely out MOCO warranty) the rivera pro clutch is a descent replacement for under $500 (i don't like spendin' xtra money on anything)
By the way Fatboy I didn't give myself "the ofender" handle [smiley=wink2.gif]
