NCY Compression Spring (1500RPM) Most Minarelli,Yamaha 50 2T

NCY 1500rpm clutch compression spring (contra spring) for Genuine 50cc scooters, Yamaha Zuma 50cc 2T and most 2T 50cc horizontal Minarelli engines. Compression/contra springs do a couple of things. First, they supply the pressure to engage the belt. They also determine the rate at which the CVT transmission changes from low to high gear. A 1000rpm spring will go into a higher gear sooner than a 2000rpm spring.
