Rode from Whidbey Island down to Seattle this afternoon in the light rain, stopped in Mukilteo for fuel, I usually just stick the nozzle in and wait for it to click off, then thats it. I have read all the stuff about clogging the vent hose with fuel. I took off and proceded about another 40 minutes down the freeway to my daughters. About a mile away from her house, I was in stop and go waiting at a light, and the motor dies...strange, never ever had that happen. I hit the starter, and it started right up, revved it a few times, and took off. Got to my daughters, bike idled OK. figured it might be crap fuel, or something got wet. Later I left my daughters, got a few blocks away, and the engine kind of acted like it was going to quit, I revved it again and it stayed running, although at low RPM it acted like it wanted to quit. I got on the freeway again, and the bike was running good at high RPMs. but I kept thinking about what was going on? I looked at my fuel gauge, and it was reading maximum full....NOT NORMAL...my fuel gauge always reads a little less than max when I fill it, and it was the same with this last fill, less than max. I immediately had canisterectaphobia and pulled off at the nearest overpass, and the motor died when I stopped. I took the key out and unlocked the gas cap, but was unable to hear if there was any sucking noise, being on the freeway with cars whipping by. I loosened the cap, put the key back in the ignition, and the bike started right up. The fuel gauge reading dropped to where I would expect it to be, and the bike never gave me another bit of problems. I'm thinkin canisterectomy....
