Just to add another incidence here; I have also experienced some gas leakage, but it hasn't been bad enough or frequent enough for me to feel too concerned. On several occasions I have been at a traffic light and caught whiffs of strong gasoline odors coming up from my Uly. It usually occurs shortly after a fill-up, but I have also noticed it when I've had as much as 100 miles on a tank. I haven't yet caught any drips on the ground where I park, but when I sense these odors, they are strong enough that I'm pretty sure more than just fumes are escaping from my tank.
I will look a little closer the next time this happens.

I've smelled serious fuel lately in the cold...I think it's just the smell of a cold bike struggling. It's not something that is coming from the tank, it's coming from the exhaust. I think, in this case, it's just a cold engine working hard. Most bike exhaust tends to smell more like gas than our cars, which never fails to alarm me for the first minute or two when the sleds are warming up.
Smells like...victory. Cancel that...smells like...Milwaukee! |

I believe I may have found the problem. I took the fuel cell vent off and made sure the ball inside was moving freely and it was. The o-ring looked to be in good shape and not nicked so I put it back together and while I was putting the airbox cover back on I noticed the fuel cell vent hose was routed in a way that would put it right up against the airbox cover, possibly pinching it. I put it under the little bracket that holds the inner airbox cover on and went for a ride (I was testing the hippo hands) and no gas leaking after a short 20 mile ride. I will try it again tomorrow on a longer ride in colder weather.

My first post on this forum and good to be here.
I bought a slightly used (933 miles) 2007 Ulysses last week and after a short 22 mile ride to bring it home noticed the same issue- fuel dripping from the overflow hose. Fuel level check showed it to be not visible so I'm curious what you more experienced Buell guys will find as the cause and fix. |

I have over 17,000 on a 2007 Uly and know several riders with varying amounts of miles on 2006, 07 & 08 Uly's, all up here in the Rockies of Colorado, and we have not seen this fuel dripping issue; full tank, break-in period, empty tank.
So I don't want to proliferate a problem experienced by a few as being epidemic.
Stay tuned.

Right on Jammer!
As soon as this weather breaks I will do some more test. |

Certainly not suggesting this is epidemic. It seems a few of us have something to sort out is all.
Logically, fuel or fuel froth would have to be at the overflow tube entrance and then siphoning or pressure behind that to start some little amount to flow down that tube. And that's as far as I've worked the glitch.
The fuel cell vent, hose routing and cap will all get a thorough going over soon as I get the new-to-me Uly up on the lift.
Might I add- The short after-purchase ride home was a hoot. |

I have not had a long ride but did a regular commute distant ride which should have given it plenty of time to build pressure in order to leak out the vent tube. It seemed to fix the problem so when you get your Uly on the lift yank the airbox cover off and take a look. I was able to determine than the air box cover was pinching the vent hose (not all the way closed) that allowed it to build up enough pressure to vent fuel but not enough to stall the bike. There is a clip that holds the hose close to the inner cover. The second picture shows the clip holding the hose like it should be. Let us know what you find!

Skinner-
Many thanks for the pics and your findings on that hose. I'll zero in on that when I do the "go-over". |

Apparently that did not solve the problem. I had to go to a friends house today 40 miles to his house and nothing. 40 miles home and it is leaking again. It seems to get worse the less gas in the tank. Does anyone else, that has the leaking problem, notice it getting worse with less fuel in the tank?
I think it is building pressure as the fuel level drops. |

Damn it, I think my uly has a STD.

By the way, Jomartijr - welcome aboard! Hope all your riding is smooth from here on out! |

Thanks, I'm really curious about how the X and I are going to get along. A quick once over suggests the bike will be much easier and accessible to work on than others in the garage. And that's a good thing as I'm a confirmed motorcycle tinkerer of the past 35 years.
This fuel overflow tube spitting problem is really puzzling/interesting and soon as I finish the present maintenance project the X will become the focus of lots of effort including pulling the suspension pieces for GMD to modify for my short self.
I hope to contribute as well as benefit from info here and have already learned some really useful stuff. |

Hi all,
I have had fuel dripping and serious vapours coming from the same tube on the left side at the rear. It worried me so I put the bike outside and checked it every 10 mins it leaked for 90 mins.
I have since found this thread from a search and know that it needs to be dealt with by the dealer. Bike is 1yr old and has 3500 on it.
I was intending to ride it up to my dealer 95 miles away to get them to diagnose the other issues, speedo fault, exhaust actuator fault and needs a new clutch cable holder,for warranty. Then ride home have them send me the parts and I send the old ones back. Now though my question is can I,should I still ride it?
Or would the dealer pick it up?
I am new to the motorcycle world, this is my first bike...
All advice is appreciated |
