Frequently Asked Questions

Q: Does this kit include the cylinder?
A: No, this is an internal engine component kit. It includes the piston, crank, bearings, and gaskets, but does not include the cylinder itself. We recommend having your cylinder measured or replated by a specialist before installing the new piston.

Q: Is the compression ratio different from stock?
A: No, the Garage Buddy piston included in this kit is designed to match the factory stock compression ratio (13.0:1) to maintain standard performance and fuel requirements.

Expert Pro-Tip: When performing a full bottom-end rebuild, cleanliness is just as important as the parts themselves. Ensure your engine cases are completely free of old gasket material, metal shavings, or solvent residue before reassembly. Use a high-quality assembly lube on all bearing surfaces and cylinder walls to ensure the engine runs smoothly during that critical initial startup.
