Expert Pro-Tip:

Rebuilding a 2-stroke engine is an art. We recommend using professional-grade tools like a crank puller and a case splitter to avoid damaging the engine cases during disassembly and assembly. Prior to installing the new Hot Rods crank, ensure your main bearing bores are perfectly clean and lightly oiled to allow for a smooth seat. Always check your ring end gap in the cylinder to ensure the rings are perfectly matched to your bore.
