One is marked 73 TNT and there is a second identical one. Others come from RVs and another set is from a 82 Blizzard Will be at Whiteout tomorrow. This motor rolls over smooth and has new. It comes with everything in the pictures including the air-box boots, comet clutch, motor mount plate and all the studs and most of the nuts and bolts..
Porting Done by Larry Crank Shop. This motor packages utilize Crank Shop cylinders with Nickicil and the benefit of the Nickicil cylinder is the way it dissipates heat. The motor packages are designed for open improved or open pro-stock racing only. These packages will include three new Crank Shop nickicil cylinders and rave valves, new aluminum billet head and domes, porting, pistons, V-Force 3 reeds, stroking the crankshaft to 73mm, and a set of triple race pipes. The parts required from the customer for these builds are the crankshaft and case, the case bolts, and all the rave housing parts minus the exhaust raves. New head bolts are an extra charge for the aluminum head or you can send in the stock bolts to be modified for a fee. So, you can see one can spend easily 10 Grand or more to build one of these motors.
Will fit all the Ski Doos from mid s though the late s. Replaces Ski Doo oem part numbers and and possibly others as well. I have a list of machines these seals will fit but its much too long to list here.
I bought the Nordic electric start and got the ashtray after some twisting the dealer's arm on the deal. I drove that machine over miles with not a hitch of repairs for two years. Greatest Ski-Doo ever in my opinion.
