Monster Big Bore Kits
Monster big bore kits are the ultimate combination of all our parts and services for the biggest, most powerful engine combinations.
We use our all aluminum Nickel Silicon Carbid plated cylinder kits that are so large, the cases must be bored to accept them.
The crankshaft is then balanced for the new components, and our CNC ported heads and cam combo's are highly recommended for ultimate performace.
