I recently did some electrical mods, added a fuse box in back for accessories. I installed a powerlet outlet in the busa for charging the battery. This is not new at all but I put mine in a different location, the small black cover on the right side of the frame cover. It probably sucks but in case anyone else wants to do it... here it is. Even if it does suck, I ride into the garage and plug the thing up..work!
