I took my wife for a ride, two years ago, with a few of my buddies and their wives. We rode for several hours, and my sled was running great. We went in to the 7 Mile Inn, and had some food, and hung out for a little while. When we were leaving, I started my sled and let it idle while I was putting my helmet and gloves on. We took off across this long field that everybody races across, and my sled just would not go. Sounded like it was only hitting on one cylinder. I shut it down to check my plugs, and was totally shocked at what I found. Some jerk off stole my plugs! On top of that, he put his junk plugs in mine. I know this because they were not the ones I run. I guess there is really no point in this, just wanted to see if anyone has ever had this problem.
