I rode through a puddle

So it might not of been a puddle but it wasn't deep. I was riding along the side of a lake today and I went through what looked like just some water sittin on the surface an it turned out to be about 8 in deep. It wasnt deep enough to touch my carb or anything but after that my bike acted like it was running out of gas you know the sputtering stuff so I stopped and gave it some gas and let it idle well after sitting for about a minute I cut if off and decided I'd check the air box to just be sure I didn't suck any water in on accident. I didn't. After putting it back together I went to start it and it wouldn't. So i turned the gas off and took all the plastics off... Again... And. Started looking around for something wrong didn't see anything took a stick and knocked all the dirt and mud that had been flung underneath from my shenanigans of the day and turned the gas back on and it fired up. I'm just curious if anyone might know why it did the sputtering it scared me a little. Btw it's an 04

Full tank of gas and nowhere to get real fast

Have you done the bowl vent "T" mod?

Some mud over/into the end of the vent hose will block atmospheric pressure to the bowl causing no fuel delivery.

I'm guessing it needs the Tee mod as well. Here's a youtube link to the procedure

NWGArider and others,
Just my opinion, but I feel it 'Is Better' to mount the 'T' or the 'Y' as close to the vent nipple on the top LH side of the carb as possible.

Then route the Added vent hose Forward, along the frame to the 'Bracket' which holds the LH Rubber Puck gas tank Mount. It tucks nicely into the 'Forward' triangular hole in the bracket, makes a nice vertical curve and keeps even a garden hose bath under the fuel tank from getting into the 'New' vent.

One can also make a longitudal 'split' about a 1"-1 1/2" long in the Lower Tip of the Down hose to reduce mud plugging.

Wish I had a digital camera and knew how to use all the computer functions better!

As a minimum, I'd suggest: attempt no significant water crossings, until you perform the Tee mod.

The carb vent hose on a stock Generation 1 has its opening approximately 10" above the riding surface. As posted above, this hose must be CLEAR for engine operation; otherwise, fuel cannot flow from the carburetor jets to the engine.

(BTW, the carburetor vent hose on a stock Generation 2 KLR650 is located about 30" above the riding surface.)

The "Tee mod," providing an alternate path for atmospheric pressure air to the carburetor float bowl, is the solution to flame-outs during water crossings with a Generation 1 KLR650.

Oh, you haven't performed this mod? Then, field expedient: Yank the carburetor vent hose off at the carburetor. At least, your float bowl will be able to breathe, and your engine will run, in water depths up to the carburetor height level.

Better solution: Buy a tee fitting and a length of hose; pdwestman has provided you with an elegant path for the auxiliary elevated hose run.
