Expert Pro-Tip:

Precision is paramount when rebuilding your 2-stroke engine. Always ensure your engine cases are meticulously cleaned of all old debris and oil before installing your new Hot Rods bearings. Using a quality crank-puller tool will help ensure you seat the crankshaft without exerting damaging force on the cases. Lastly, always check your ring end gap in the cylinder to ensure a perfect fitment for optimal compression.
