Hey guys, I recently picked up a slightly used (1200 miles) 2014 550f skidoo renegade. I owned a 2008 550f gtx a couple years ago so I am familiar with the engine but this one is acting strangly. I live in the high arctic and this machine is my family car. We use it to go to work, take the kids to school, groceries as well as playing on the weekends and extended hunting/fishing trips. It gets run everyday. I keep it in an unheated outbuilding. My old gtx had to warm up for about 5 minutes then it ran fine. This one after even ten minutes idling it still sounds like it is not running fully on both cylinders. It is running rough. It leaves quite a black patch in the snow. If I hop on and go, it bogs, misses and sometimes backfires until it is fully warm, then it runs like a top. I just checked and replaced the plugs. The one on the clutch side was pretty gunked up/black. I put in NGK 3194 br9e6 plugs (did not gap them as I did not have my gapping tool yet) and this helped a bit but it is still an issue.
It is cold here (-28 celcius) already and it does get down to -50c. The skidoo 550F is one of the more saught after machines up here because they are so reliable, light and easier to work on.
So, besides checking the gap on it (this next weekend, along with a belly pan and heavy duty hitch install), any thoughts? Maybe a higher quality plug? I realize I could let it warm up longer, but that is not always a reasonable possibility.
