Good luck. You can still order some parts straight from Japan, but even there it is hit and miss. Most parts for the´79 can only be interchanged with the ´78. It is one of the last years that have both a kick start and automatic. It is only a 6 volt, and most are now 12. Salvage is the name of the game. Luckily its a single carb and easy to work on. Get mechanic manual, and wiring diagrams.
