While riding down a steep trail in WV, had a back fire and sudden lose in compression. 2004 Sportsman 700 twin, total lose of compression on the right side. Was able to ride on a single cylinder for about 2 miles to a shop to determine the problem. After getting it home, will not crank at all. Could the EBS and the steep grade may have caused a jump in time? Any suggestions prior to tearing down would be very helpful.
