Just returned from a week of riding in Colorado with my 2000 WR400, and had some problems at water crossings. It seems that when I cross streams or rivers about axle deep or more, the motor will die. It usually will restart fairly easy after one or two kicks, but I would like to cure the problem. There is no water entering the air box, which leads me to think that the problem is electrical. The speed that I cross the water does not seem to matter either, as the problem occurs at super slow speeds as well. Should I spray WD40 on the plug and coil wires before riding for the day? Other than that, the bike rips and is a blast to ride, even at 12,000 feet elevation. I don't recall having this problem in previous years of riding the bike. Any thoughts?
