okay guys new problem. Put a new contra/torque spring(Polini +20%) into my super9 to try an eek out some more top speed and hill climbing. now i've gone from 74+kph on the flats to 61kph with my hill climbing speed about the same. but my rpm's have gone up by 1k on the flat(9k) and down hills(10+k).
The rest of the CVT is pure stock with the rollers at a stock 8.5g. I have extra rollers in 7 & 7.5g weights as well as a Green Malossi spring
thoughts
thanks.
