Some people simply should NOT be allowed to work on their own bikes. I have a customer and friend that every time he try's it winds up being twice the work to fix, Having to undo what HE did to it. Another "friend" of mine thinks EVERYTHING needs painted, Including the chain. Trying to get through 3 or 4 coats of paint to get to the screws is a PITA. Anyway, I took a couple pics of a bike a customer FIXED. ALL he wanted to do was replace the clutch pads, So,I sold him the pads, explaining to him that he might have to resize them to fit and that pads from one supplier may not fit the clutch from another suplier. In on ear and out the other. He brought me the bike complaining the clutch wasn't working properly. what he had done was to jam the too large pads into the too small holes leaving the clutch plate out WAY too far. You can see what the result was.The flower nut lock screw cut a perfect hole in the case.
