I was riding last weekend and the sled started to run poorly. I cant get more than 6500 rpms and over 40mph. I tried new plugs and the old ones were soaking wet. New plugs did not solve anything. I was wondering if anyone had ideas of what might be wrong. I understand the 04's had a crank seal problem was wondering if that could be the issue or maybe my dpm is not responding correctly. Any suggestions would be helpful. thanks
