Well I took the bike to TWO dealers and they both looked at it and told me it was okay to ride, as long as I keep an eye on it. One guy told me he would love to take my money, but I really didn't need to change it out just yet. I asked one guy about going with the thinner belt so I could run a fatter tire, and he said not to. He said that the thinner belt means less area. He said if I had the thinner belt now, he would recommend changing the belt. But the older and fatter belts were tough and the width meant they had a lot of area in them. Both of them related similar stories about running belts with holes in them for years and never having problems. So I'll continue to keep an eye on it. If it starts fraying or shredding, I change it out. It's not a big deal to check on it since I check my tire pressure quite frequently.
I know this sounds cynical, but I do believe that if my bike breaks down on the road, it will be due to another stator failure, or my Zippers ECM taking a dump.
