I live in alaska and have not heard of any failures at all.
I will keep trying to find any news I can. If you're thinking
of buying, do it! This sled has been the best that I have ever owned
so far. You'll love the torque, make sure you get it with a camoplast
141 or the hard durometer 144, you won't be dissapointed!!!
As long as your turning them at stock rpm's they will live. If it's over revving because the clutching isn't right fix it, and don't do mods that raise the rpm. They will be as bullit proof as the 600/700 motors, just don't spin them up. I've heard of 2 that broke but they were mucho modded, all the stockers have been reliable around here.
