The last time my bike needed a coil to run, my dad--being the electronics wiz that he was--designed one and made it work. He is gone now but left behind a drawing of how he made this thing. It makes no sense to me. So I´m left with where to go to buy one now that I need a new coil again. Apparently these things quit working often enough. . . . .ugh! The Honda dealers tell me that the part has been discontinued. Anybody know where I can get the part so I can run my bike? Thanks. Bren
