Description
If you’re running a Yamaha Phazer 1984-1989, piston wear directly impacts compression, power delivery, and engine longevity. The Wiseco 73mm +1.00mm overbore piston kit restores lost displacement and sealing integrity, giving you measurable gains in throttle response and reliability whether you’re carving trails or competing on snow.
