We offer genuine Yamaha crank-shaft rebuild parts for the classic Yamaha Sno-scoot 80. We offer bearings, connecting rods, and crank pins. We also offer a full kit that includes everything shown to the left. Please be aware the replacement of the connecting rod and lower rod bearing require a skilled engine machine shop for disassembly and reassembly of the crank (parts press together and have to be aligned properly). Select the parts that you need in the drop down menu below. All of these parts are stock replacements for all 1988-1990 Yamaha Sno-scoot 80 models.
