What I don't get about that guy that hits all the forums with the 550 horror stories is why do they still run them? I read his thread a few years ago, and he said the rebuilds weren't lasting a day! I guess I don't doubt him. A fleet sled at a ski area probably doesn't get normal use, but why keep using something that doesn't work? If a sled gets rebuilt twice a week, that's a lot of parts and labor cost. Pull the plug and sell the fleet. Someone will show up with a few semis and buy the whole fleet. Then they could buy some 4-strokes or liquid 2-strokes. Why keep wasting money on something that supposedly doesn't work? It was originally the Edges he was talking about, and now they're buying IQ's and complaining about them. Holy crap! Ski Doo, Yammi, and Cat make sleds too. Give them a try or something.
