Gas leaking from my tank when it gets hot. - April 6, 2010, 01:50 PM

I came back from lunch to find a steady gas drip under my bike. When I opened the tank, I heard (and felt) a WOOSH as the pressure opened. I figured that the problem was over, so I closed the tank. About an hour later I checked again and there was a slower leak. I figured out that the vapor was expanding, so I left the tank open, moved the bike forward about 2 feet (to dry pavement) and waited. Nada.

I'm guessing that either the more volitile winter gas is expanding in the heat and forcing the liquid fuel out of an overflow tube, or that there is a pressure valve that has gone stupid. What should I be looking for in the manual?

Spaceballs is one dumb ass movie. I'm surprised I had to tell you that.

Pressure valve gone bad... just my guess... but I would start there.

Happened to both mine and my wife's bike today.

We filled up this morning.....gas station is only about .1 mile from the office. Went out around lunch time and they were both dripping.

Go and don't worry about it.

Check to make sure your gas tank vent line is not clogged. Did you just fill up? In hot weather do not fill your tank all the way up and then park it in the sun.

+1 on the fill up.....plus gas is heavier and negates the small salad you had for lunch...lol

exact reason why my car never has more than 1/2 a tank lol!!


Can't choose between the R1 and the 10R so I am keeping both but settled with an 1198S when I came home

Keep it up!!!!!!!
