Hey guys, I got my '04 wr 450 f about two weeks ago. Mechanically the bike is great. Starts easy, runs smooth. The only issue is the guy I bought it from put a light kit on it to make it street legal. Everything works except the headlight. If I turn on the ignition all turn signals and the horn work but the headlight will not come on until I crank the bike. The headlight also does not switch from high-beam to low-beam. Also my brake light only brightens up when I press the foot brake. Being a mechanical engineer I know just enough about electricity to get myself in trouble. Any suggestions or thoughts on what may be causing this?
