I won a 2003 Ski-doo 600 Rev in a promotional contest. The next day I got in a wreck while towing it. It flew off the trailer, but had very little damage. It is back out of the shop for broken fairing and bent handle bar. Now it smokes a lot. The guys at the shop say it is normal, but when I rode it before the wreck, there wasn't that much smoke. Any clues?
