I have a question that I hope the forum can help me figure out.... I have a 2015 M8000 limited 153 track with approx. 2200 kms - I've owned since new and am old (50yrs) and a mediocre rider. I don't jump or abuse my machine in any way. I do go to the mountains a lot. Here's the list of upgrades that have all been done by my dealer: Upgraded shocks to raptor front and rear, upgraded running boards to proclimb, 2016 front end, skis,there's more, but its not pertinent to my issue. I noticed in November (prior to first ride this season) that both sides of my tunnel at the upper supports were starting to bow out (no wrinkles) - nothing major, but I weigh approx. 240lbs and thought the issue was because the stock Fox 2 air shock was bottoming out at 140lbs pressure all the time creating a lot of stress. I then changed out the rear shock to a raptor and adjusted the spring tension to where I had full movement of the suspension, but did not bottom out. However, I was riding this past weekend with my dealer (riding buddy) and noticed near the end of a ride (was rolling the machine over to get unstuck) that the issue of "bowing out" was back. This time though it actually bent the upper suspension supports and broke rivets on both sides - like bent enough that both supports (all of it) need to be replaced. Don't get me wrong there were a couple subtle hits on the ride where the suspension was cycling through, but the snow was deep and it was minimal - it even bent the Skins rear bumper. Anyway, that's a lot of force..... again no jumping or abuse. My buddy (the dealer) can't understand what the hell is going on to create this issue. I told him we are not fixing it until I understand what could be happening. Oh, I do carry a 3.3 gal jerry can on the tunnel. Oh, one last thing... it must be bowed out at least 3/16 to 1/4" both sides. To say I'm pissed is to say the least... THOUGHTS?
