Aloha, Variator and reed cage are ok. You just need to know how to tune your rollers. Do you have a Tach on your bike, if so then find your power curve.
Several easy and general ways to do this.
1: slowly accelerate and find at what rpm your power comes on and/or go full rpm with light weights and see at what rpm your power stops (do not count overrevving). If for example your power stops at 11,000 rpm then the very rough rule is that the power curve is about 25% to 30% of your rpm range. 11,000/25% is 2750. Subtract that from 11,000 and you get a power range of 8250 to 11,000 rpm. With the middle of 9625 rpm. This is the engine speed of 9625rpm that you will want to tune your roller weights to. This again is a VERY ROUGH estimate (max power mostly is not in the middle) and according to how well your cylinder is matched to the pipe, how wide range rpm is your pipe, 25% to maybe 33% of your total rpm range is about average for a street pipe. Then right away you need to tune your carb to be sure you are not running rich or lean.
