just bought the 2 sleds of ebay and the black 95 has a piston down, i am sure the owner never knew as he wasnt a big sled head. but none the less it not firing on that one. has some commpressionh but no fire. One of the airboxes was missing tabs so wonder if it went threw and blew skirt off. Cleaned carbs, changed plug wires around and plugs and cant get nothing out of it. and its down on my guage about 15 pounds comp[ared to the others. Any other ideas?
