..the agility really opened up for me, with the 1500 torque drive spring, and some +15% increase in the clutch "fly" springs....to get even better top speed, replace your variator with a malossi multivar, with some lighter roller weights...
..maybe 5.1 grams...i like ninja sliders, instead of rollers, but that's just me..lol...
...what year, kms scoot you gots??
