Dr. Pulley RACE VARIATOR
The best racing variators available on the market for your CN250. Racing Variators increase both Take-off and Speed. We have included a set of (6) Dr Pulley Slider Weights for this Variator made of high quality carbon and nylon. They slide in and out of this High Performance Variator in order to increase and improve the performance. This will allow lower gearing to wind out more giving you a substantial increase in low end power. You'll achieve better acceleration, greater gas mileage, less vibration and no roller clanking. Upgrade your stock CN250 for a smoother ride. Select your Sliders in Product Options above
This Racing Variator from Dr. Pulley is precision engineered to increase performance over stock variators. Specially coated ramp plates create less friction on the Sliders, allowing them to adapt more rapidly to changing driving conditions and resulting in less wear
This Dr. Pulley Variator comes with the Variator, (6) Sliders, Fan Plate, and Center Boss Pin
MAIN CLUTCH SHORTY TORQUE SPRING
We have selected the Red "SHORTY" High Performance Main Clutch Torque Spring for this kit. The Red Shorty Spring engages at 2000rpm which is the same as the Full Length Blue Spring. The Red Shorty works well with this kit
The clutch Main Torque Spring keeps tension on the belt and counters the force of the slider weights. Along with the slider weights, it controls the shift points.
Replacing the stock clutch Torque Spring is an inexpensive upgrade that can increase the responsiveness of your Buggy.
The main torque spring makes it harder for the variator to draw the belt inward on the clutch. This keeps the buggy in a lower gear ratio at higher RPMs, and "downshifts" faster when decelerating so you're in a lower ratio when you hit the gas again.
A stiffer main spring shifts the CVT system faster, giving you more power when coming out of a corner or going uphill. Even better, a clutch torque spring does not affect your top speed!
Note: Using lower weight rollers (15-16g) with this spring can affect your top speed due to the rollers not being heavy enough to fully overcome the spring's tension.
We recommend 17 - 19 gram sliders
Add the Kevlar Drive Belt in Product Options above to complete this kit
