Performance engines
When you build one of these engines, some combinations work and some don't work that well. We really put the required time into the building process. We have the most up-to-date porting and cylinder program's. Dyno and track tested combinations that perform. We have different combinations for everything from 65's to 250's. All brands. We do not sell big bore kits. If you want performace, we need your complete engine. All engines are AMA legal.
Engines: All prices are using your engine and carb. All engines have new crank bearings, rebuilt and modified crank, pistons, gaskets, and SPEC sheet included on all engines. Price's are based on a specific package. You will receive your engine 100% assembled and ready to install. All new parts.
Price's do not include transmission or clutch parts.
If you want a National level engine,look no further. We pull all the stops on these and are full tilt race engines. That
have proven power and reliabilty. Must run race fuel.
Pump gas engines/heads available also.
We build your engine to the power band you want.
The engines listed are just some examples we offer.
All engines receive the following:
Cylinders that are bored are resurfaced top and bottom before being bored. This way you can be assured you have a good gasket surface and a bore that is square with the cylinder. Cylinder head re-cut and re-chambered for the head design chosen and volume/squish/msv. Porting for the port timing and area that is chosen. Power valves cut to new bore size (some engines receive power valve mods), rod modifications, crankshaft modifications. Crankshaft stroking and balancing. Every clearance is perfectly machined to very tight tolerances. Transmission disassembled and inspected.
We have a new KTM supermini engine

custom port's and porting, power valve modification, custom re-chambered head,
