I have the exact same bike same bike, black, racks all around ect. except the engine model number of my bike is KF.82D-X. I bought my bike about back in '84 used from a local ATV shop. I went back to them to get a belt for it but low and behold they don't supply them any more. When I asked if a could find out who the supplier was they said they don't know. When I asked about any technical info they said they tossed everything on this bike. Now I am stuck with a stationary bike (hopefully only temporarily). So if anyone has any tech info I would appreciate it too.
