Post by bobbygerard »

Hi guys
Im having a issue with my gearing. I dont want more top speed. I want better acceleration. Don't care if it reduces my top end speed. Any suggestion for my setup. Im currently running stock gears. :coolcruise:

G'Die:

Is everything in the belt case working like it should? That setup with stock gears should be a rocket in a slingshot off the line. Sometimes a greasy (or too narrow...) belt will slip and undermine the take-off. Same goes for the clutch. You don't mention your center spring, but they do fatigue with use and allow the belt drive to shift up too soon, dropping Roo's revs and sapping the neck-snapping Thrust. A fresh spring will correct.

Also be sure your carb is adjusted to compensate for running upside-down, Down Undah. :)

I got home from the mines next week so I'll open her up and have a look. Only 2000kph on the scoot so it is just the rollers. Tuning is good. I throw a kevlar belt on aswell
