It's the vent. This is mostly a problem when tank is half full or less and the fuel is heated up by the pump. I had heard you can add an older style vent to remedy this but don't know specifics. Usually I leave the bike outside for a half hour or so before putting it away. Also, I noticed that when the fuel is cold the smell is far less. When I fill the tank and ride home a short distance I am able to go right in with little to no smell.

 

I don't smell any gas when I go into the garage, but I leave a shop fan running to keep the air moving anyway, don't like it being 100+ degrees with two bikes with gas in them.

 

Well the source of the gas smell has been found.
It wasnt the Harley. It wasnt my ***, But it wasnt the OLs car either.
It was the Honda 150 dirtbike. Found a puddle under the swingarm when we just came home. The petcock was in the on position and it was coming out the carb overflow tube.
****ing riceburners.

 

Glad you found it. I think there is a different smell when you have a few drips and when its just engine heat making the tank vent. The latter is more like the smell from say gas logs with a hit of gasoline. Real liquid is overpowering. Had a fuel filter with banjo up on the side of my 4x4. It had a slight crack. Took me months to find it. Finally found it at night with a flashlight. It was dripping behind starter. Wife had threatened to use a lighter. She hates the 4x4 and the Harley and when they smell the adjacent den she gets even more testy about them.

 

It's a vented gas cap. Wrap a strip of cloth from an old t-shirt around the cap.

 

Guess you are joking but Harley's cap is not vented, the tank is vented to a down tube.

 

I fill my RG with gas every night when I get home. I park it with a hot engine in the garage and it nearly always smells like gas a little bit.

One night I got the bike really full of as and rode a few miles instead of going straight home. Out of curiousity, I decided to check and see how much fuel I'd used. When I took the cap off, the gas had expanded and it splashed and overflowed out of the gas tank.

That's with a 2012 RG and a 6-gallon tank. My 2006 with its 5-gallon tank was never a problem.

 

true dat

 

I got the little thing fired up and rode it around a bit. Im gonna sell it and buy or trade it for a 1911.

 

So you're going to trade one malfunctioning piece of crap for another? Get a Glock 21SF. Runs great every time!

Isn't this a beautiful work of art? And works great!!
