The first time I forged a relatively small stream on my 04 450 it came to an abrupt stop. The starter would crank over but absolutely no indication of a spark. Once it was dragged out it fired right up. I didn't take this very well. The water was only up to the shifter when I came to a complete stop in the middle of the stream. Is this an electrical feature of the bike or could it be a carburetor overflow hose issue? Thanks!
