88cc Big Bore Performance Kit (52mm):
- Lightweight aluminum cylinder with steel sleeve
- Cast in mounts on cylinder for aftermarket skid plates
- Oversized cooling fins on cylinder for efficient heat dissipation
- High compression 52mm piston with rings, pin, & clips
- Head gasket kit
We recommend purchasing a high volume oil pump.
Installation Note: It will save a lot of time and effort if the oil pump is installed while installing the bore kit (requires cylinder removal).
***** NOTE: NO INSTALL INSTRUCTIONS ARE PROVIDED BY TRAIL BIKES *****
