Water in fuel can cause a sudden cutting out. It really can mimic an electrical problem. And sometimes if takes full throttle (and enough vacuum) to suck the water up from deep in the Carb Bowl. (water sinks in gasoline)

Draining Carb bowl or tank worth a shot ... can't hurt!

Not likely as the ignition and charging systems are completely separate.

Gas cap may not be venting properly.

My first guess would have been the inlet filter, but you BTDT.

If you're jetted for the open airbox, just closing the opening (closer to stock), you'll be jetted way too rich.

Seat decisions

Sargeant vs Seat Concepts kit.

I need a comparison. Both in how the long term feel is and their shape / construction. How they effect seat width and height between the two would be great.

Sargents is very comfortable. But I prefer the Seat Concept seat I have now. I like a little narrow seat profile and I like the texture of the SC seat better. Just my .02.

I have no comparison to make.

My purchase (today, in fact) of my first Sargeant saddle was determined by them creating a whole new seat pan from which to build off of. Sounds like a reasonable idea to me.

Did that to no avail, but thanks. There was some remains of an IMS gas cap in there which I removed and replaced but it still had the miss. May be that pesky sidestand but it sure would seem that it would be an issue in rougher terrain

Passive, cheap modifications

For example:
  • Magnetic oil plug
  • Fuel cap, fuel filter bag
  • Lucas fuel treatment (not as passive, but quite helpful)

Can anyone think of more?

Thanks for all of the replies. I have checked the fuel tank cap and vents, no clogs there. It has an IMS tank. The petcock came with the tank. It's a basic three position one; off, on and reserve. The stock vacuum operated one was removed.

I've had the carb apart so many times, the float bowl is clean. I also replaced the float assembly not long ago. I took the bike to a local shop and they put a rebuild kit in the carb (needle, emulsion tube, o-rings, etc...) None of that helped either.

I fiddled with the side stand this evening and don't think that is it, but I will try a bungee cord on it next time I ride it.

I'll look into more of the electrical side as well. I had to replace the stator at the end of '11 because it lost spark completely. Fortunately, I am an EE so if it is electrical, I can probably track that down.

Here's how you bypass the sidestand switch:

That's a good video explanation and belongs in Krusty's Index.

I have to give a big thanks to everyone who said to check the side stand switch.

I jumpered it out this evening and took the bike for a test ride. It ran great! No stumbles at all.

The way it was acting, I don't think I would have guessed that would have been the problem.

Once again, Thank you everyone!

Yep, it's decieving but your symptoms were exactly what we see when the switch is just starting to fail.
