Has anyone changed their rollers to a better bearinged roller. Who makes them and where can i get them. I want a perfect fit, no modifications. Will the MSR rollers work ? If so what are the part numbers ?

 

I am not sure what rollers you are referring to, but I am guessing the ones that take the slack on the chain. After a few months, both of mine began to freeze up and the chain eat thethe rollers up. I had them apart on a sunday afternoon and no place to get new ones. I stumbled on some of my kids roller blades in the garage and some extra bearings. They fit perfectly in the rollers and are a much higher quality than the stock Yamaha. I have had them in now for about 7 months and not one problem. The original just froze up and came apart. I don't think they like water. If you will give these a try, I think you will be happy with them. They area sealed bearing and inexpensive to boot.
