High-Performance Racing Variator Kit for Chinese Scooter Moped ATV 4-Stroke GY6 100cc 139QMB 139QMA Engine Front Clutch,Variator Drive Wheel Assembly with 8.5 gram Roller Weights

My scooter didn’t like it from the beginning. And ended up chewing it up and ruining my original roller weights. The best thing I can say is that with the roller weights that came with this, my top end has increased, but so has the time it takes to get to driving speed. The entire thing was a mistake purchase. Poorly made, broke AND melted.

Este producto es mejor de los gue yo esperaba el Sccoter ahora es mas velos y mas fuertes es muy notable el cambios en este scooter despues de instalarles esta nueva pieza con variadores incluidos

half a variator better than nothing I guess ,should have paid attention.

Advertised as 6.5-gram roller weights. Mine came with 8.5-gram (actually 8.6) which might be OK for a 100cc vehicle, but certainly not a 50cc. I noticed another comment saying the same thing, but just figured at worst I 'd have to buy lighter weights, and might want "sliders" anyway. Still disappointing because even cheap weights are about $10.00 shipped when purchased separately, and these should have been right.

Performs exactly as described. I went with a heavier roller weight configuration with my bore kit, but allows slightly better belt travel.

It lasted about a month and a half before the variator kit,crack and the roller started to show used!!!

Seems like good quality.very happy with purchase.

I like this item after the installing I feel the moto. A quicker pick up at the start.. great item

Excellent
