I bought a brand new 2012 M8 Sno Pro this year and I got approx 150km's on it and it decided not to start. I checked for spark and the spark was very intermitent and it kept fowling the plugs when it would run. Took it to the dealer and they said the wiring harness was shot so they replaced it with a new one. Is this a common problem with this machine or has any of you experienced this same issue??

Yep 12's had a problem with harness routing and the wires rubbing chaffing then either shorting to ground somewhere or shorting to another wire. The harness itself is fine its where its run. Joys of being the first year model of a new chassis. Then usually this burns out the stator as well. Happened to my 12'. Cost me the $1100 stator (in Canada we get hosed!) and labour to repair the harness as then trace the rest of it to make sure it's good. Make sure to trace the taillight wiring and all of the harness wiring for that matter to make sure it's not rubbing on anything sharp. Even a plastic edge of a panel will run through the crappy protector on the harness. Hope that helps clear it up for ya.

Buddy has a 14 M8000 and he has been stuck out on the Mountain twice. Both times were due to the wire harness going bad.
