My gl1800 is giving a petrol smell when riding. I've noticed this since I fitted the CB radio to it a while back, but I didn't disconnect any petrol lines and I didn't have any problems during the job either.The fuel cap is on tight but I can smell petrol fumes form the general area of the fuel door. Any suggestions from the good wise folk here would be appreciated as I am lost for clues and I prefer not to let the dealer touch my wing unless it can't be avioded.

I have no clue where the problem could be coming from, but I know how to take baby steps when looking for the problem.

Going from what you have said, "smell when riding" do you smell it when it is sitting in a garage? Little help on that commit.

"CB radio" new helmet or not? (looking for a glue smell)

Did you check the fuel cap for faulty seal?

Look at the air filter. (can't hurt. mine smells like gas all the time)

I hope this pushes you in the correct direction for solving your problem.

Eric,
If thefumes weren't there before you did the CB install, then the only thing I can think of is you may have kinked or blocked the tank breather somehow. It's a few inches in front of the filler cap but you will have to raise the shelter again to get at it. You can check if it is kinked by opening the petrol cap and then getting about a metrelength of12mm inner diameter hose and fitting it over the breather tube that comes out at the bottom of the engine (near the main stand), taping them together for a good seal.Blow through the hose. If it's an effort to blow through or if you can't hear the blow coming out of the filler neck then the breather is blocked. You might have kinked it when refitting the shelter, it does happen and I know a few 1800's that came back from dealers after the ECM fix with this problem. Kinked breather was the cause.
You've already had the shelter off for the CB fitting, so you should be able to do it easily and in good time this time round.

I think you are probably right Steve. I always susoected that it was down to something I did wrong, left off or connected the wrong way. I'll do that test and if the shelter needs pulling I'll do that this weekend. Thanks for the input.

I think its the darned breather all right. I have a small Draper compressor that I would be include to use for testing a blockage.

I'd say you are all right about the breather. I tried pumping some air into the breather tube with a bicycle pump taped to the tube (had to find the right one), but the sillypump almost choked on the feedback. After a bite of lunch I will have a go at the shelter. Thanks for all the help.

[align=center]Done!![/align]
It was the greyish breather tube! I pulled the shelter and found that when I had fitted it last time, the black plastic edge at the back of the radio wasn't sitting right and was laying on the breather, which I had also incidentally somehow moved a bit as well. The mark of the plastic edge is visible on on the breather, clear evidence of my error. I think the trick to avoiding this is to take note of the breather position before fitting the shelter and actually looking under the shelter fiorm the back while lowering it (just like when you are refitting the radio antenna).

You're lucky that the fumes didn't make you groggy while riding, you could have dropped off, literally. I think you will be more careful in future. :gunhead:

I don't suppose there was a chance of the bike going up in flames? At least we can learn from your mistakeYELLOWWING. Thanks for giving us the heads-up.
