This sled was purchased in 2005 from a couple in the Muskegon area.  It was a "his" and "her" package.  I can't remember if it had a burned piston or if I just decided to have the motor modified.  I believe I had it bored .20 over and had the cylinders ported(performance) and polished.  Some of the studs came out on reassembly and were replaced with larger ones.  Motor has Nology wires and coils and Boyesen reeds. Track was also replaced with a used one out of Canada at the time. Sled is extremely fast and fun to ride.   Fuel systems will require a complete cleaning to put it back on the snow.  Seat is supple and fiberglass is nice and shiny. Overall it is a very nice sled.
