Hi, a few months ago I noticed a bad noise from the rear of my bike. After cleaning the belt, tension resetting, a bearing change, I finally realized that the pulley and belt are both 'striped' or corrugated (don't know how to properly describe it). The bike is virtually unridable at the moment, as the noise is really annoying. I do not know the reason for that, just heard that this is not unusual for Raider 12 SCL's. A new pulley and belt looks like a must, but I'd like to avoid the same problem in future. I'm wondering if someone else has the same experience with such issue.
