I have an older Victory XT. Normally runs like a champ. There are two belts side by side. They broke. (when one goes - the other is not far behind) We replaced them. It ran for a month with no issue. Two days they broke again. We put on two more - two days later they broke again. What is going on? Anyone have any thoughts? - They are aligned correctly...not too tight...not too loose. What the heck?
