This is a low mileage engine (2123) that was in perfect running condition when removed from a wrecked sled. Once removed the engine was disassembled for inspection and checked for tolerances. Cylinders were freshly bored. New SPI molly coated pistons +1.00 were installed and Windorsa gaskets were used. Windorsa crank case seals were installed. Wiseco wrist pins were used and factory oil pump was cleaned and serviced. Installed are 2 new NGK spark plugs.This motor includes 2 new exhaust gaskets.
This engine will swap into any ski-doo 500 with a yellow cylinder head on it!
