NCY PERFORMANCE 11 GRAM ROUND ROLLER WEIGHTS

 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

Great quality roller weights for scooters using GY6 150 engine in scooters and go carts. 
Lower your stock weight (12-14) with 10s or 11s for a great performance upgrade
 for better take and just plain replacing worn out stock weights.


For those of you unfamiliar with roller weights, they are an important tuning device and 

have a significant impact on your scooter's performance! 

They should be checked/changed every 1000 miles (per maintenance schedule) to keep your scooter running tops. Over time, roller weights will develop flat spots which will impair the performance of your scooter.

A good indication that your rollers are worn is increasingly high revs for a given speed and/or decreased top speed. Replacing worn rollers with this set will restore and actually improve your low-end power and especially your top speed. Fuel efficiency will also improve dramatically!
