Description

This Prima Roller Weight Tuning Kit is the best way to dial in the CVT transmission on your Genuine Buddy or 157QMJ 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 WILL SEVERELY DAMAGE YOUR ENGINE!
