Yeah alot of times I seem to get hung up on atv ruts on hillclimbing,cases out,I can hear the rocks hitting the swingarm/engine skidplate.I was wondering what I could do to give it a few more inches of ground clearance w out stink bugging the handling or making it top heavy like its predessor 660?

I don't think you're going to be able to do much about this problem other than maybe try to change your line when going up the hills.You could put on taller tires;but that would affect the handling.You could try long travel suspension;but it won't help the rear end.My quad hits and drags too.I got some good skidplates and try to straddle the ruts or go around them.I've also found if I go faster I can sometimes "glide" over the deep stuff.
