My 74 is in pieces now and I have started degreasing the parts so I can see what I have. The first items I'm working on are the frame, center stand and side stand. Both are very worn. The mounting holes in the center stand and in the frame are egg shaped and the side stand appears to have had an upgrade welded in place on the frame but all pivot points are badly worn. Does anyone have some technical specs on the diameter on the holes for these parts? I am debating whether I should have them welded up and redrilled or just ream them out til they are round and make custom bushings. Do I really need a step bushing on the center stand?
