I went to my local piece of crap dealer for some help on this, and they basically all made it to six grade and no further, with this simple question. How much heated clothing (Gerbing) can I run before I have to worry about draining the battery. I'm talking about just going down the road, not stop n go. I understand it doesn't have an alternator like the 12gs and that it puts out 400 watts, but I don't know how much of that 400 watts the bike uses with everything that it runs (lites, blinkers, pumps etc.) Does anybody run this clothing? any problems? I've run gloves and vest with no problems, now I want to run pants. any thoughts, info would be appreciated. If you live in the Atlanta area and need assistance with BMW anything- avoid BMW of Marietta- they treat you like you're a pain in the arsse.
