I just Installed the Amazon NCY Variator kit yesterday...BUY IT!

My kit came w 1000lb clutch spring, 10g rollers... my stock gray color rollers were 12.7g worn.
I just ordered Dr Pulley 13.5 Sliders for my 190lb weight, on a little 150cc Tao Tao VIP GY6 157QMJ... the 10g NCY rollers were good to 1/2 throttle, but a bit revvy for flat WPB roads.
I feel my motor can turn a higher gearing. I am wanting a powerband from 1/4 - 3/4 throttle and the 10g rollers I thought would do it better, I feel like its revving out too much or I need a taller gearing. FWIW my scoot is tuned well. Perhaps a lighter clutch bell than NCY next, and a yellow 1500 clutch spring.
I did change my internal 3 clutch engage springs from the red NCY, to my stock springs that engage the clutch at about 1000rpm, which is handy for ultra slow riding smooth.

Update: The Dr Pulley 13.5g Sliders are just a tad too tall a gear, it pulls bit better low/mid, mid-3/4 'just' struggling to accel, 3/4- full 'slowly' winding out, for general tall gear cruzing its nice. I concur with some reports out there that the 12g sliders would be 'perfect'
