'06, same problem afer a long ride.

 

No fumes from my 07 UC. With the way emission standards are, there's got to be something wrong if it's venting.

 

Check the overflow tube where it connects to the tank overflow spigot. Mine had split - found it removing thetach/speedo coverwhen I installed thetank bib on my Dyna. There was nothing there to hold it on to start with. It won't be leaking with less than an overfull tank, but the vapors do escape the tank through it.

 

I took my bike in to the dealer saturday. They inspected the overflow fitting under the tank panel. Checked the gas cap and could notfind any problem with the bike. They told me to ride it and report back.I rode it home from the dealers about 20 miles and had some small fumes coming from it in the garage. Yesterday i put 75 miles on it, parked in the garage with both cars left out. I left after about 30 min the fumes were starting to build up. I came back in an hour and the fumes were so bad you could smell them in the car pulling in with the windows rolled up. The entire garage had filled up with gas fumes. Had to leave the door open till they cleared. So Back to the dealer it goes. The saga continues...

 

It's just the hot engine heating up the gas tank and the vapors are venting. After parking your bike, feel the bottom of the gas tank after a few minutes to see what I'm talking about.

 

It is trying to tell you it doesn't want to be put in the garage.

 

I have an 08 Ultra and during the colder fall weather always stop at the gas station at the end of a ride to fill up....I don't over-fill, but I do fill up. Frequentlyl I'm coming home from a 100-200 ride and park in the garage. I can smell the hot engine and exhaust pipes but never have had any kind of gas smell with this or any other bike I've owned. Something isn't right if it smells that bad.

 

With the new EPA standards, vehicles have to pass a test where they come off the dyno and into an evap shed. This prevents manufactures from bottling up vapors during the test and then releasing them later, like when you turn the bike off and park it in the garage.
The vapor pressure from the gas is normal, but the closed system on new bikes is designed to prevent it from getting into the atmosphere.
Could be something a simple as a hose clamp.

 

I don't have that problem w/my '08. I usually let it sit outside for about 15 minutes or so just to avoid all that heat in the garage, but no gas fume smell.

 

had that for awhile with the 07' about 2-months went away.
