Variator Roller Weights
 (Set of 6)

8 gram rollers will reduce top speed and acceleration but will    greatly enhance climbing and low-end gains.                    10 gram rollers offer a good blend between acceleration           and low-end gains.                                                           12 Gram rollers, will still improve low-end but are best                suited for acceleration gains.

High-Performance Clutch Bell for GY6 150cc Go Kart engines
For GY6 150cc engines only. Available in 8, 9, 10, 12, 14 grams/weight - Set of 6 weights Traditionally, the gear ratio is changed by the up-and-down rolling movement of the roller weights in the ramp of Moveable Drive Face (MDF) of the variator. Now the innovative Dr. Pulley Sliding Roller Weights slide up and down in the ramp of MDF to change the gear ratio. This unique sliding movement provides exclusive advantages to make CVT perform excellently: no abnormal wear will occur; even when Dr. Pulley Sliding Roller Weights work in the high gear position. Fits all 150cc buggies & motorscooters. These sliding roller weights are the latest design made out of extra strength nylon. They last 20% longer and are over 18% more durable. This new sliding design variator outperforms our MRP Variator by 8 points on dyno meaning that if you want to race then you need the Dr. Pulley variator design. The kit brings everything you see here including the pin, race fan, variator, cover and slide pieces. IT DOES NOT INCLUDE ROLLER WEIGHTS! Bell machined out for lighter weight & optimal cooling. Fits all 150cc buggies & motorscooters.
