Carb Vent Tee?

The way this problem comes and goes so abruptly,I think it may be a sticky valve.When I put gas in the intake,I held my finger on the vacuum line and felt good vacuum.Of course it started then.So if it is a sticky valve,it may have cooled off and closed.Atleast I'm not setting my tent up in the middle of nowhere.

Don't know how often I will get to use the internet here.At least I'm1500 miles farther from home now than the last time the bike quit.
Doug, JohnF from Cincinnati. I had an '08 KLR and remember doing the "Carburetor vent line Tee modification". That modification was to install a tee in the float bowl's vent line. The reason was to allow any water that may have become "stuck" in the vent line to drain out. With the tee the bowl would be vented to atmosphere by a tube that runs upward to an always dry location under the tank as well as by the original vent line running downward. If the vent line becomes "plugged" with water the results are erratic fuel delivery. That's just a WAGuess but worth trying. Best of wishes for your adventure!
