Yes I have a 4 speed engine here. It should have been from the 83 or 84 frame I had. It was running great last year. No smoke or anything. We took the whole pike apart to paint the frame and my son lost interest in it.
I have the carb and electronics as well. I couldn't find the carb slide,spring and top for it. I just have to sort through some parts and find it. PM me if you are interested.
