Description

Prima roller weight tuning kit (15mm X 12mm)  with 2-gram to 13-gram roller weights compatible with scooters with Jog, Yamaha, and Minarelli clone motors.

This is the best way to go about tuning your CVT transmission!

This tuning kit includes 12 sets of 3 rollers, for a total of 36 roller weights. These sets range from 2g to 13g. Combining 2 sets of rollers allows you to tune with a large variance of weight sets!

Examples:

Using the set of 10-gram rollers and the set of 12-gram rollers, alternating weights in variator, results in an 11-gram roller set.
Using the set of 10-gram rollers and the set of 11-gram rollers, alternating weights in variator, results in a 10.5-gram roller set.

TIPS: Lighter roller weights will increase RPM for any given road speed.
Heavier weights will lower RPM for any given road speed.

Tailor your engine for your desired goal of acceleration, top speed, or tune to your performance engine set-up & personal driving style!!
