I just scraped my 4 inchers for the first time..... Took a torch to the backrest and re-bent it so the ol lady would be more comfortable. Took her for a test ride and damned if I didn't hit a bag going out the driveway. Took a nice nick out of the bottom rear edge. Glad it happened now and not in a couple of weeks, as it's all going to paint next week. I'll be making skid plates for them tomorrow. Here I've been worried about dragging in the curves, and didn't even get out the driveway......
