TB 88cc Big Bore kit, Race Head, & 20mm Carb Kit – K0-78 Models

TBparts complete 88cc bore kit, Race Head, and 20mm Performance carb kit. This complete 88cc Race Head Kit will really wake up your stock engine and is comparable in power to the much larger Chinese 124cc engines!!! They are extremely reliable as well! Made to our specifications turning your worn-out stock engine into a high-quality, high-performance engine that makes big power!

Starting with the 88cc 52mm Big Bore kit. Our aluminum steel sleeve cylinder is super lightweight compared to stock and it also helps with heat dissipation. The piston is high compression but safe for 91+ octane pump fuel. The bore kit also includes the top end gasket kit that includes all the gaskets for the job. Next is the race head included in this kit. This is what really sets our kit apart from the competition especially considering the price. When you replace your worn-out, carbon built up stock cylinder head with our new complete bolt on race head you get a ton more performance and power. Better geometry allows for a bigger cam, larger valves, and bigger, better porting. Plus, it is made to our specifications to keep quality in check with OEM standards. This is extremely important when turning big RPMs and making big power. Top that off with the 3mm larger 20mm performance carb kit to feed the new larger displacement engine. This also includes a port match manifold with all the necessary hardware.
