Yamaha Ovation CS 340 long track. It was a 108" track now its a 121" track with rail extensions. The track has 1" lugs and now is a 2.52" pitch with new drivers to match. Carb rebuilt and new fuel pump. Runs great and starts easy. Great kids sled but adults can ride it too. Seat is completely rebuilt with new seat cover and wood seat pan. Simmons flex skis so it steers much better than the old scrappy metal skis. Bill of sale provided and old registration.
