R1150RS fuel smell after parking in garage

[gallahadion]

I've just bought a 2004 R1150RS and when sitting in my closed garage, a fuel smell lingers in the air. The smell is strong just after I park the bike in the garage,
but is there for days after I park it. I've only had a the bike for a week. Can anyone help diagnose, or lead me down the right path to look for the culprit?

Start with the seals on the gas cap.

Fuel line quick disconnects is the first place to look, especially if you have the original black plastic ones.
Do you see any moisture or yellow stains on the silver engine paint?
Good luck and welcome to the site.

Start with the seals on the gas cap.

And make sure it's completely shut.
Does this model have a problem with the tank warping at the gas cap opening?

After you check the quick-disconnects check to see if the bike has had a “cannisterectomy”; a removal of the charcoal cannister that is part of the emissions equipment. Removing the cannister and venting the tank directly to atmosphere can produce a lingering fuel smell.

Best,

Bikes of this vintage and earlier start to have fuel line age deterioration.
The lines harden and shrink under the clamps. Fuel begins to weep by.
I've replaced more and more sets lately.
Use SAE30R9 5/!6" fuel injection line along with the proper fuel injection clamps.

Possible internal rubber line leakage

Check around the fuel evaporative canister to see if the smell is strongest there or there is actually visible fuel. There are rubber lines in the tank which feed vapor to the canister and at about this age and who knows how many years of fuel contaminated with ethanol they can split and leak fuel into the canister.

Honda Pacific coasts were prone to that and in its case, it was the vaccum operated petcock. Gasoline evaporates quickly, so smelling it days later, means it is still leaking where ever it is.

A long time ago I had one of the clamps under the tank come loose. No idea how that happened, but a small screw type hose clamp fixed it.

I strongly suspect that DeVern hit the nail on the head in post #5. I bet the charcoal canister has been removed and the fuel tank is vented to the atmosphere via a 2nd hose to down by the right foot peg.

Here's a picture for the OP if he needs it.
