I tried searching but couldn't find anything that sounded like my problem, and I am using a friends computer so I don't have all night to search. The last couple of times I went riding on my 04 wr450f the strangest thing happened. I had already started the bike and had been riding for awhile both times when this happened. I was just cruising down the trail and my electric start just started engaging on its own like I was holding the button. If I pushed the kill switch it died but the e start just kept cranking until I turned the starting circuit on/off button behind the headlight. I would let it sit for a minute and turn it back on, and both times it seemed to stop but only temporarily. I dual sported my bike and used a tusk control switch. In order to cut back on handlebar cluster I wired the e-start into the horn section on the tusk switch. I rode it fine without any problems for almost a year before this happened so I don't think I wired it wrong. I just ordered a new switch because a faulty switch is the only thing I could think of that would cause this problem. I am hoping the switch is the issue but I wanted to ask some people who actually understand the starting system on this bike if there was anything else that could cause this. Any input is appreciated, thanks.
