The gas gauge on my 03 rev was useless, asked my dealer about it did not say much. When I ordered my 04 rev I asked him if they fixed the gauge, he said the got the problem figured out. Even in one of the snowmobile mags, I think was sno goer they said it was fixed. Not the case with mine or my buddies brand new one. It showed empty and we had over 5 gallons of gas left, dont get me wrong I usually use milage as a gauge but it would be nice if the gauge was close. Love the snowmobile, hate the gas gauge its really my only complaint. I have a X model why dont they just make a clear tank on it, they offer it in there accessory mag for 200 or more dollars. Guess I will have to orderone!
