Was riding in the rain to the antique motorcycle show.All of a sudden the engine died,and wouldn't restart.I suspected an electrical problem.However, i loosened the fuel cap and then the bike restarted.
Rode with the cap loose and got home ok.
Checked the fuel tank breather hose for blockage-OK
Here's my theory,the water build up on the tank vent hose(rain) actually plugs it off and stops flow to the carbs.
This has never happened in the dry.Bike only has 1800km's
:???:

The tank vent hose has a little plastic valve in it that gets stuck easily. I replaced my tank vent hose with I believe an inexpensive windshield washer hose from a auto parts store.
Technically, the breather hose is the large (about 1/2") hose on the top of the crankcase that allows air to flow in and out of the crankcase and keeps the movement of the pistons from pressurizing and depressurizing the crankcase.
The tank vent valve was screwed,put a vacuum line union in its place. That valve is put there for a reason,have you had any problems after removal?Such as sucking water or dirt into the tank.
Have all the New Bonnie owners dumped this cheesy little valve?
Look at Gary's PDF file about removing the EVLS system in the downloads section. He mentions stuffing some kind of filter material in the end to keep debris out. The file mentions what kind of material he used.
This little valve is actually a roll over protection.Designed to stop the tank from emptying,if the bike is layed down.
I tested the valve by blowing in each end,Horizontally -no air flow.Vertically- air flow in both directions.
Hope this helps somebody,highway breakdowns suck!
a monza cap will take care of that little problem, and keep your neck from peeling
