2002 skidoo summit 800 just rebuilt. top end was sleeved and bored out at Keller machining in Mandan with oversized Wiseco pistons 83 mm instead of the standard 82 mm. has new v-force reeds. the engine was out of a 2005 so it is the H.O. Engine, I have put about 50 miles on since rebuilding I installed new crankshaft seals on both ends and greased the bearings while I was in there, I used the iso flex and petamo grease not crap grease that is not supposed be in there. New carbides and the brakes have been flushed. Comes with a can and the original exhaust. any questions please dont hesitate to ask, has no reverse and no electric start this is the summer price, September 1 it will go up.
