ok i have an 03 raptor 660 and its burning oil really bad. i had it in a little while ago to have a new clutch put in, but the guys i had do it didn't put in the lower front motor mount bolt. As a resalt it cracked the valve cover. they fixed that but as i started riding it again it started to burn oil right of the bat. it has been getting progressivly worse sence then. i talked to a local dealer and they said it was probably the piston rings (every one els agrees) untill i went to a different dealer and they said that it was probably the valve seals and the gaskits. what do you guys think...i'm really stumped on this one...any one got some advice?
