Unhappy Help - Bike stalling

So until today my bike was pretty solid. It started up fine this morning. I drove myself and my girlfriend to brunch at a restaurant. Then it started up again just fine after we were done eating. Dropped GF off at our apt, then got back on the road for a 3-hour ride.

After riding for an hour, I stopped on the side of the road to take a scenic picture. I started the bike, put it in 1st and eased on the throttle while easing out the clutch. As soon as I let out a bit of clutch, it STALLED. It didn't lurch; it just died. I started it up again, making sure the kickstand was up after opening the gas cap to clear any vacuum. Started fine, revved fine. Eased out the clutch - STALL. Again. Eff me.

I happened to be on a hill at the time, so I figured I would try rolling it into 2nd. I start it up, get it rolling down the hill in neutral, shift up to 2nd, then let out the clutch:

Well it stayed running, but any throttle input just made a "whooooom" sound. No power, no rpm change. Eventually I got to the bottom of the hill and the engine slowly braked itself to a stop.

My first guess is a clogged float valve, but that would only affect one of the cylinders. And why all-of-a-sudden after behaving just fine all day? And while I was passing through a state park that was closing in an hour? And in an area with no cell reception?

Any suggestions before I tow the bike back to the garage?

It is the safety switch at the side stand. Spray WD or the like and work the switch. This should take care of the problem. You can by pass it, but fix it as soon as possible.

I just lubed the side stand a couple months ago. It has plenty of grease on it and swings out with ease.

How can I bypass it?

I do believe he is talking about the electrical switch itself - not the stand. sometimes the switch (which will kill the bike when the clutch is let out but the stand is still down) sticks or gets corroded on the inside and the thing will stick in the down posistion. Try unpluging it and shorting together the wires and see if you can get it to take off. If this is the case, you will most likely have to replace it.
Hope this helps.

Try squirting some WD-40 inside the rubber boot over the safetey switch plunger. Helps mine when it goes to doing that. When I'm on the road and it acks up, I just lean over and pull the plunger out by hand. Be careful you don't tip the bike over though! Probably be safer to put it on the centerstand and pull it out.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Before I drive an hour to the no-cell-reception region where my bike is sitting, can anyone describe where this plunger is? I can't find it anywhere in the manual, and I'd hate to get all the way out there and not be able to find it.

The switch is close to the top, front of the sidestand, where it pivots. The sidestand leg itself pushes the plunger in when it is in the down position.

Do you have access to a pick-up truck and ramp, when you drive out to get the bike? It would be nice to have a plan *B* for getting the bike home, just in case you still can`t get it started.
