Clutch Rear Pulley '02-'11

This NCY adjustable secondary sliding sheave has two sets of ramp angles,
one steeper than the other.

These allow you to adjust how quickly the pulley engages. A quicker engagement means more power off the line, and more gradual engagement gives you more power at speed.

This is a major  performance improvement!

(using genuine yamaha parts is over $300 and does not have the performance)
