Well i know this sounds crazy but i ran a Honda 600RR in my mini sprint this year and i also know another guy that ran a 636 in his and both mine and his was about 2 inches from the ground and he had a skid plate welded on his and had no problems and i didnt do anything to mine and had no problems (LUCKILY) But that is the only way i could figure out to mount my motor to get it to line up. Hope that helps. :2:
