Remember posting something like this a few years ago but can't seem to locate it.
I have suzuki dr400s (1980 model) which has a 6 volt battery. Is there a way of wiring a Zumo 550 to the bike by adding some electronic wizardry to it. Somebody sent me a possible link to how to do this but lost it. (Use to have a 1150gs but for medical reasons sold it as it was a tad heavy and the better half didn't want me getting another heart attack) . Got a couple of extra batteries for the zumo but would rather have it wired to the bike if possible.
