I have a 2003 WR450. I removed all of the lights when I bought it for a cleaner look but I had a street legal e-line kit put on recently b/c of gas prices. Soon after the kit was installed at the dealership the e-start stopped working (kick starts fine but I bought the magic button). The dealership says that the stator went bad and the battery is weak, both need to be replaced. I have had zero probs with the bike until the kit was installed. Seems like too much of a coincidence to me but I don't know enough about it to determine if I am being hosed or not.
