any ways to keep belt slip down other than new belt, pulley, or mt?
its the whipple with stock sized pulleys the whipple has the 3.00 pulley
Do mean you have a Whipple (with a 3.0 pulley), with all the stock belt pulleys? If so.. that is your belt slip problem.
I'm running a 3.0 pullied Whipple too.. but, with BF idlers. Serious belt wrap, no slip...
