I found what appears to be a 1971 fuji go-devil colapsable mini bike in the trash here in mpls MN it hadn't run in many years(the gas in it was muck) I'm kinda handy with all things mechanical so i started tinkering and had it running in a couple days i had to replace the throttle cable and drive belt(i just guessed on the size and made due with what i had)and the clutch fell apart a few days later. does anyone know anything about them. are they worth anything, are parts available, should i be riding it around town, would it be bad to modify it? sorry i dont have pics but any answers you could give would be a great help. thanks
