This adjustable Secondary Sliding Sheave Clutch Pulley Assembly from NCY will give your Yamaha Zuma 50 or Jog a quicker takeoff and a higher top speed. With two sets of ramp angles, one steeper than the other, this set lets you adjust how quickly the pulley engages. A quicker engagement means more power off the line, and a more gradual engagement gives you more power at speed. Fits Yamaha Zuma 50 and Jog.
