Built With Precision Parts
Our cylinders are re-plated by Millennium Technologies, one of the most respected nickel-plating companies worldwide. For steel-sleeve engines, our in-house boring achieves perfect piston-to-wall clearance and a flawless hone pattern.
Once engines are received they are fully dissembled, cleaned, and fully inspected. We inspect everything, crankshaft bearings, rods, true, and index. Engine cases are fully inspected for damage cracks or excessive wear in bearing journals. Cylinders are checked for pitting, scarring, and cylinder wear to see if it’s out of round or tapering. We do not charge for disassembly or diagnosing your motor.
We’d love to talk to you. Give us a call and we can answer any questions you have. No question is too big or too small.
