I was riding with a local club (mostly jap an italian sport bikes). Stopped to fuel up after some "spirited" mountain roads. Filled up the bike.. in about 5 minutes, fuel was draining from the overflow tube. All in all, about 50 cents worth on the pavement. It seems that the hot surroundings of the bike made the cold fuel expand as it heated up, bringing the level higher than "full" I don't think I like the location of the overflow tube... not far from the exhaust tip. If this were happening while riding.. and a backfire occured... ??? Has anyone experienced this?? By the way... I'm new to the board.. I have an 05 City Cross. Hello! | ||

I have had the same thing happen on my 04 XB12R. I've only had the bike 1.5 weeks and both times I filled it up, I had the same problem with the overflow. The second time I did not fill it up as much as the first time and had less overflow, but still...... Is the only remedy to stop filling well before the fuel gets to the filler neck? | ||

Fuel puddles happen in the cold too. Problem is - with the price I pay for fuel there was probably £1 ($2) under my bike when I noticed! The overflow seems to kick in too early, and it spills out in entirely the wrong place. I always make a point of not truly filling up now. I only joined board yesterday, so hello yourself!  | ||

The manual instructs the rider to fill only to the bottom on the ring at the bottom of the filler. | ||

Rubberdown, that's what I did the first time and even less than that the second time, and it still overflowed. Guess, I will leave it at least an inch or so below. Rox, welcome!! I just joined a week or so ago myself!! | ||

That's odd. I had overflow out the tube that exits by the swingarm once. I'm pretty sure I overfilled it. I guess these tank are subjected to a lot of heat. | ||

That's normal, read in your manuel and it will tell you the level to fill it up to to avoid this. I've done this a few times.... The overflow line should be routed to just behind the left pedel. You would see some plastic holder there that will keep it away from the pipe. | ||
| Ratyson |
Yeah, that is where the hose is routed. However, that is only a couple of inches in front of the tail pipe outlet. I may look into an alternate location for this, but I'm not sure what kind of luck I will have. | ||

Once the bike is upright and running, you will not have too much fuel for very long. I would not worry about the location of the outlet, Erik and his team did the research so you would not have to. | ||

yes, gasoline, like most other fluids does expand some when heated. if you wish to waste less gasoline on the ground, take care not to OVERFILL your fuel tank, which is of course in close proximity to your motorcycle engine which is quite warm during and immediately after use. this is detailed very clearly in the owners manual. | ||

If it is hot out and you park a hot bike right after filling it up you fill certainly see enough fuel expansion to cause overflow. The gas will come out of the underground tank and something close to the average year round temperature for your area. Up here in Wisconsin I would think it is easy to get gas coming out of the pump at 55 degrees, add in a 90 degreee day, a hot engine and you will see a lot of expansion of the fuel. Worst I have ever seen was a very pretty black Harley parked in the sun after a ride and a fill up. The gas was coming out of the filler cap at a pretty good rate. |
