We contacted Hot Rods and ordered up a bottom end kit, which comes with the crankshaft, main bearings and seals, and a complete gasket set. It also included a Vertex piston and rings. We sent the cylinder off to Millennium Technologies for a re-plate. Here is a look at our rebuild of the 2 stroke engine. We highly suggest having a service manual by your side when working with any engine and wish you good luck!
