I just bought a 1984 XR 200 for my wife. It came with a prolink from a 250 on it. I am desperatly trying to find out what year the prolink and the rear tire are from. that way i can buy bearings and sprockets for the rear tire. Are all the rear tires from honda from 1984-1989 the same as in the sprocket mounting holes and the bearing size. I sure would like some help. they are worthless over on the XR side of things. You are all great. Dont worry i still worship the blue beast. Just need help on the red side for a change.
