Ever since I had a clutck kit put in it slips the belt in high if I gun it from a dead stop. It does not do it in low, I can do wheelies all day long if I wanted too, but in high the power comes on gradually. This is the second belt in 2 weeks. Can someone please help me. I am wondering if I ought to go back to stock. It is a hpd kit. The dealer is getting tired of looking at it for free, and I am tired of taking it to them. HELP!!!!!!!!!
