Expert Pro-Tip:

Precision is paramount when rebuilding your 125cc 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. Always follow your service manual for exact torque specs, as small 125cc fasteners are sensitive to over-tightening.
