Bought some sliders the other day (Dark Horse) and the front right side is too big for bike. I have a 03 XB9R. It is just slightly too large. Starts to fit, but doesnt set all the way. The axel has a slight roll edge on it that is why it starts to fit but then stops. I dont want to beat it in because I would never get it off when needed. What is the best way to make them fit? Grind the resessed part down a little? They were bought used from a guy on here, so I can't just return them to ASB.
