No, not from riding into water anyway.

But water in the fuel causes very similar symptoms.
Motor will idle but won't rev.
Got stuck in the middle of nowhere once after filling up at a country petrol station. The key to getting out was to let the bike sit for awhile and the water settles to the bottom of the tank. Pull the fuel hose and drain the tank until the colour changes. Then drain the bowls, it was a 4 pot bike, then you're good to go.

But carby cleaner is a great time saver.

Don't rule out the interlocks.
Granted that in most cases the bike will not run or even start if these are faulty.
But, switches aren't always either on or off.
When they are failing they can show resistance.
This can cause very odd faults.
And when semiconductors are involved, well lets just say, don't rule em out.

Ok, don't rule them out, but I wouldn't jump on them first either. It's a fair assumption to say the interlocks would cause either an intermittent stumble or completely kill the engine regardless of RPM. That's not the symtoms he describes.

Nothing is absolute, but just sayin....

Agreed, it's not where I'd be looking in the first instance.
But I've ruled things out in the past and it can come back and bite you.

Plus, they have no place on a bike anyway IMO.
In the bin.

All true. The first time you drag a kick stand is more than enough to create a 'mental interlock'

I've been using the same station for fuel since I bought my bike, so I have faith in their fuel. The only thing I can think of that changed is they switched over to the winter fuel not that long ago. But I still had about 30 or 40 miles used of the current tank before this issue struck. I'm going to try some of the suggestions after work today and give some more feedback. Thanks to everyone who has replied so far.

Did this last night, it actually took longer than I thought to get the engine to finally die. When I turned the fueld back on, no change in its behavior.

On a side note, i could get the engine up past 3000 RPM via the choke. Could this mean I'm running lean?? And if so, why did the bike run great (no sputtering or stalls) for the last 100+ miles?

I think there is crud in there somewhere.
Probably main jet.
Choke circuit is compensating.
