Hey guys, just wondering if any one has had problems blowing bulbs? I have a 2005 wr450 that blows the headlight and tail light bulb within 60seconds of running like its over charging or something....anyone have any ideas?

possibly the regulator? measure the voltage across your battery terminals with the bike running.. shouldnt be above 15 volts

Most likely, the regulator. Also check the regulator plug (poor contact)

Give a man a commission and remove his brain. Good to see you are keeping up the fine traditions of the RAN. :banana:
