Went up north last week riding, didn't go as well as we would have liked. My dad hit a tree at 13 miles into the trip, totaled sled out. I got a total of 60 on mine and somehow poked a hole in my heat exchanger at the very back. Got to a resort and the guy running the place was nice enough to try to braze it shut with some aluminum rod, but didn't work. So now I need to change it but really don't know how to go about it. It looks to me like I will have to drop the suspension down and probably take the seat off. Am I correct? Thanks in advance!
