I have a 650R that I want to add an adaptor to plug in my GPS and run it off the bike. The bike has the stock stator and I run a 55 watt headlight which is the best I can do in it's stock form. My question is, can I hard wire an adaptor from the headlight to power a GPS? I know I would need to put an inline fuse or something to prevent frying my gps unit when the power surges. I have a 1200 mile ride coming up soon and don't want to carry all the batteries needed to keep my gps working for all that time. Any suggestions? Yes, I know I should just suck it up and rewind the stator, but I don't see the need for that as of yet.
