The Hot Rods Complete Bottom End Kit for the 1999-2000 Yamaha YZ 250 includes everything needed for crankshaft installation and a full engine rebuild. This kit features a factory-assembled Hot Rods crankshaft, main bearings, seals, and a complete engine gasket set. The crankshaft meets or exceeds OEM performance standards and is fully rebuildable using genuine Hot Rods connecting rods. Owners can choose between a Heavy-Duty OE replacement crankshaft or a Heavy-Duty Stroker crankshaft, which increases stroke length depending on the application. Some modifications to the cylinder head may be required when using the stroker crankshaft. This all-in-one solution ensures a reliable and precise bottom-end rebuild for your engine.
