I'm looking at a used 07 R and it is in great shape, hardly any wear on the clutch cover, no wear on flywheel cover. The guy said it was all origional but he doesn't seem to have noticed that it has a boyseen quick shot on it and that the spring on the shock is red not yellow. He bought this from the dealer thinking it was bone stock but it obviously isn't. I'm worried if I buy it the new suspension might be set up wrong for my weight. What kind of money am I looking at to fix that? What kind of suspension would be red? Any idea what is on there?
