Naraku HD variator weights 18x14, 8.5g for scooters, quads, ATVs, buggies, etc.

The weights in the variator transmission determine the change in the gear ratio ("shifting behavior") while driving. These weights should always be adjusted during tuning measures to increase performance. This prevents the variator from "upshifting" too early, thus preventing the engine's potential power from being utilized, and also prevents the engine from revving too high and becoming damaged (and/or increasing fuel consumption excessively). Worn rollers should also be replaced so that the transmission shifts smoothly and does not seize. When tuning the variator rollers, the rule of thumb is: the lighter the weights, the later the "upshift" occurs, thus the engine revs higher; for sporty driving. The reverse is also true: the heavier the rollers, the earlier the variator "upshifts," and the engine remains in the low rev range; more suitable for leisurely cruising...
