I was wondering if there was anything wrong with the 020 belt? The reason I ask this is because when I put on the orginal belt(020) I get a hesitation at wot, I thought at first it was because the belt was getting old, so I bought a new one. The new one did the same thing. So then I tried an a ZRT 800 belt (010) and this solved my problem. So I was wondering what would cause my 2 blets to do this, Fault in the belts or is it something elese?
