I hit a washout and bent the rear of my tunnel. Has anyone had any luck straightening them out?
I was thinking of takeing the seat plastic and exhaust off and placeing the rear of the sled under an arm of a hoist partly raised and useing 2 floor jacks one under each rear suspention brackets to jack the sled against the hoist. I don't know if it will work. I'm sure some others have tried something to repair the damage from the buckleing of these weak tunnels.

Nothing against being creative on that repair, but before I tried something like that, I might be tempted to show it to a couple of body shops. If you could find someone there sympathetic to snowmobiling, he may be able to work some magic for you very reasonably. Have seen it done.

What actually bent?
Did it bend like we've seen some of the 06 GTs bend?

Yes it bent just like some of the 06 gt's. But mine is a rtx.
I did manage to hammer and beat it back to some what it's original shape, I am not happy with the weakness of the tunnel.

Before I rode mine I installed all of the reinforcements that Yamaha added to the 07 GT. Mine has not bent.
A buddy of mine called me last night about his 2006 Apex ER to tell me that his tunnel was bent at the back though. He didn't install the reinforcements, rides hard and has not revalved his shock. He does have the big boy spring installed on the 2nd clip position, but he still bottoms it out hard all the time (he claims it doesn't bottom out much, but I don't buy it). He also discovered that his muffler and muffler support are completely shredded through from the studs hitting them when bottoming out.
I believe it is the hard bottoming out that causes the tunnels to bend (most of the time). I refuse to ride a sled that bottoms out hard and with my revalved shocks and rearched springs mine really doesn't bottom out hardly at all (my muffler support does have a few scratches in it from the studs hitting it though). On the other hand I keep breaking pivot arms near or at the main shock mounts...
I'm actually heading out right now to install a further reinforced front pivot arm on my 07 RTX. The tabs that connect to the main shock mechanism fatigued and cracked away from the front arm on my last ride (12,300 km on the sled). With them broken, the main shock's lower mount can flop forwards and backwards and this actually creates a somewhat firmer ride.
I have to admit it really bugs me that all of the guys I ride with who ride REVs and REV-XPs are not having any serious suspension issues (other than a couple of loosened off bolts on the XPs). Some of them ride quite a bit harder than me and some of them have a lot more miles on their sleds too. The Skidoo suspensions are definitely much stronger and more durable plus they are not having any issues with bottoming out or buckled tunnels either. The only major problem they all had with the REV-XPs are broken driveshafts (and Skidoo already has installed an updated, stronger design on all of their sleds).
One of my buddies actually called me up about an hour ago and tried to bet me $100 that my heavily reinforced suspension would break yet again. He also suggested betting that no-one I ride with would ever break their stock REV suspensions. I didn't take him up on either bet...
