I removed the small factory style battery, enlarged the battery box, built a new tray and installed a car battery....never have a low battery issue since. For easier boosting to another bike I installed one longer positive cable and attached it to the rear plastic window, which acts as an insulator, to a 1 inch long stud and nut to act as a terminal. It has a removable rubber boot when not in use for boosting. The negative terminal is just the bolt for the seat belt harness so they are in close proximity for cables, about 8" apart. Will always keep the larger battery charged during idle or driving from the factory regulator and stator.
