DR PULLEY PERFORMANCE 8 GRAM ROUND ROLLER WEIGHTS
 Dr. Pulley 18x14 Round Roller Weights for 125/150cc 4-stroke GY6 engines. Gear ratio is changed by the up-and-down rolling movement of the roller weights in the ramp of the Moveable Drive Pulley (MDF).
Now the innovative Dr. Pulley Round Roller Weights roll up and down the ramp to change the gear ratio. This unique rolling movement provides exclusive advantages to increase CVT performance. With Dr. Pulley, no abnormal wear will occur even when running in high gear. We recommend starting performance upgrades by changing the variator roller weights first. Heavier roller weights= A slower take off speed with more acceleration and a higher top speed. Lighter roller weights = A faster take off speed with less acceleration and lower top speed FITS JONWAY, JMSTAR, ROKETA, SUNL, TANK, PEACE, TAOTAO, GATOR AND MANY OTHERS SHIPS FROM DENVER, NC |
