This is gonna sound pretty "FNG" to a lot of guys, but I gotta ask for some help. I'm not much of a mechanic, so hang in there with this rookie. I can perform basic maintenance on my 2010 Ski-Doo GTX, but that's about it. If it's not on Youtube, I'm probably screwed. Anyway, this problem's got me wondering where to start and I'm hoping someone can point me in the right direction. Maybe I can fix this myself? Maybe give me a better idea of what/how to tell my dealer about the problem?
Machine: 2010 Ski-Doo GTX 550 fan
1) I left it out in the cold this past week for the first time. The machine is ALWAYS stored in the garage. It started fine, but wouldn't go forward or reverse. I assumed it was just a frozen track, and after some pushing, lifting the track to get it spinning, I was able to get it moving. It seems to "lugging" though. Put it back in the gargage to warm up.
2) Yesterday, took it out and for a long trip. I noticed again, that it seems to be lugging along. Like the track doesn't really want to turn. I can't get up to the same speed I used to at a particular RPM. Have to give it A LOT of gas to get it moving. I guess it kinda feels like the brake is slightly always on...but it's not?
3)Gas mileage has drop significantly. It was never great on gas, but consistent at 90-100 miles per tank (~10 miles per gallon). Yesterday, I was flat empty after only 45 miles!? 4.5 miles per gallon. The exhaust smells A LOT like gasoline...different than it's usual 2-stroke smell.
All I know is something's wrong. I'm not really sure where to begin? I guess I'll change the belt and chaincase oil...I just don't think that's gonna do anything. Could be the track? Brake? Carb? I don't know, for some reason the engines working too hard for the output it's getting?
What do the experts out there think? Anyone else have these problems before? I realize it's probably something simple, I'm just new to these machines. Thanks for any info you can give me.
