Had a post here about my GF riding my buddies sled, sled tipped and throttle went wide open. From what I know now, the reed on the Mag side exploded. Sled had 140 on PTO side, 70 on blown reed side. This sled, a '01 600 MC EFI, has over 3000 miles and nothing has ever been inspected on it. And he rides it hard. The power valves have been cleaned once since new. To store the sled, he puts some tranny fluid in the pistons, pulls it over a few times and puts it in the corner of the shed. These are stock reeds. My thing now is this, this is a mechanical failure, am I or my GF responsible? A frindship and sledding buddy are at stake, but don't want to be forced to pay for a motor because of a $13 part.
