Prima 18x14 Roller Weight Tuning Kit, 6g to 17g for GY6, 150cc / 125cc

This Prima Roller Weight Tuning Kit is the best way to dial in the CVT transmission on your GY6 engine to suit your driving style.

Specifications:

• 12 sets of 3 rollers (36 total)
• 18x14 rollers
• Weights from 6g to 17g
• Combining 2 sets of rollers lets you tune your transmission to suit your driving style (lighter weights = higher RPMs, heavier weights = lower RPMs)

For example, using 3x 10g and 3x 11g rollers (alternating weights in variator) gives you 10.5g roller set.

DANGER: Weights must be installed in an alternating pattern (120 degree angle). Otherwise, YOU CAN SEVERELY DAMAGE YOUR ENGINE!
