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

We recommend purchasing a high
volume oil pump kit.
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). Also see the Performance Info section for more information on our performance products.
