I bought my sled last summer and finally put a few miles on it a couple weeks ago. Me and my wife noticed a huge difference from my old 04 mxz 550ss. This thing rides amazing!! If it wasn't for the Arctic cat in the group overheating constantly it would have been a great trip!!! I left all adjustments from the previous owner and it was set to the firmest setting all around. Me and my wife might be close to 300 lbs together. Where should I have this set? This weekend it's going to be me and my son (about 220 lbs together) and I knocked it down to the middle all around to get an idea for a starting point. We trail ride in Wisconsin. My other question is should I have a spare belt? I thought I read somewhere that there don't really eat belts like the 2 strokes. My sled has 3500 miles and don't know the history for this belt. Thanks for any help!!!
