This is probably the best way to go about tuning your CVT transmission! Included in this tuning kit are 12 sets of 3 rollers, for a total of 36 roller weights. These sets range from 3g to 14g. Combining 2 sets of rollers allows you to tune with a large variance of weights sets! For example: 3x 10g & 3x 11g rollers (alternating weights in variator) gives you 10.5g roller set. DANGER: weights must be put in a 120 deg pattern! If not, SEVERE ENGINE DAMAGE WILL RESULT!!! TIPS: Lighter roller weights will increase RPM for any given road speed. Heavier weights will lower RPM for any given road speed. All of this, of course, must be tailored to each person's engine set-up & personal driving style!! Please refer to our handy chart for more info. Brand: Prima Fits: Genuine Buddy 50, Black Cat, Rattler, and RoughHouse fits and compatible with Honda Ruckus / Zoomer Vespa ET2 (pre-'98) Kymco People 50 And More!

Good set of rollers for tuning and setup!The only complaint is that the tray os a wee bit flimsy and unmarked, besides that take a photo of the rollers in the package BEFORE opening so you have a reference point.Keep in mind this is a set ONLY for tuning and initial setup. These are NOT rollers for permanent usage.

Finally able to properly tune the weights on my 2003 Honda Metropolitan. I was so tired of buying sets of a single size. Now I can mix and match and find that sweet spot. For me I am running a mix of 6g and 7g weights.

Awesome product for the price. My only complaint is the weights are not marked so be mindful of which ones you are using. And each weight is a set of 3 not 6. But I have 5 and 6oz weights in my ruckus and am loving it.
