    Could be a short in "across the start switch button wire connections" or it could be the start relay contact "sticking", or it could be a "broken spring" in the solenoid that allows the contacts to come together engaging the starter when you hit a bump.

    The first thing is, did you do some recent electrical work around the handlebar controls, starter drive or near the fuse/start relay areas? I would start where you did any rework that required you to "dig in" and inadvertently caused some collateral damage.

    I would pull the switches off the bars at least on the right side and dissassemble them. See if they are all corroded up (sort of a green colored salt). Scape that off and then clean with contact cleaner (don't get it on your paint!). Then spray with lube and reassemble. Spray again and then mount the switch gangs back on the bars.

    Try that anyway. At least you will eliminate the easy stuff.

    TQ

    If you unplug the starter relay after starting it and go for a ride, you'll find out if it is the solenoid or the bike wiring doing it if it doesn't crank again while riding. If it does do it, then the solenoid is probably the cause.

    Sometimes it's the seat of the pants tests that separate the Techs from the mechanics.:s

    Don't discount Glider's advise on this. I had the same problem three weeks ago and did exactly what he suggested. $7 and a new relay later, I am having no problems.:p
