Great buy
I have a custom honda ruckus with a gy6 swap the motor is a gy6 150 cc motor not big bored yet with 11 gram rollers it cruises at 55 no problem and goes 61 flat the fastest I've gone was 66 but was sketchy at that speed with a 171 cc bbk I easy see this motor hitting 80+mph I definitely recommend it and it is worth every penny

Better top speed!
By changing to the 18/36 gear set, off the line acceleration is a little slower however, overall top speed is much better! Compensated by changing from 13 gram roller weights to 12 gram weights. Great product at a great price.
