It will need a working voltage regulator. On pre 1975/6 bikes these will have to be retro fitted and I have attached Yamaha's Service Bulletin on this below. On bikes after this period they were fitted as standard. I believe that they were generally quite reliable, but you never know.
If you need one and can't find one on ebay etc, then forum moderator DEET sells them (I think!!).
Good luck and don't give up!
