My WR450 battery began to go dead even when I was riding at high rpms. Therefore I thought it wasnt charging or the battery was bad or both. The battery passed a load test and had as much as 13.5 volts. However, it didn't seem to be charging so I installed a new Baja Designs rectifier/regulator which myself and BD thought would solve it. It didn't help. It actually got worse to where the battery got really weak and the bike began to run hot for some reason and I couldnt have the lights on or the bike would die. I have no idea what to do. Does anyone have any suggestions?
