Smelling Gas

Postby jtimgrant » Wed Oct 02, 2013 11:25 am



Is it normal for these old wings to smell of gas after riding? Just after parking mine [while still hot] I smell gas. The smell only lasts a few minutes. Could it be gas fumes from the carb bowls since the carbs are vented to atmosphere?

I found the fuel line at the carb on my 84 had hardened and dripped just a tiny bit.I saw it drip just once while the bike was idling.
The hose had some cracking inside where it coupled to the carb nipple.The outside looked fine.
You might replace both sides of the fuel pump and feed line.Use new clamps too.

You might also smell gas fumes if the gas cap is not sealed well,leaking or there is any gaps in the air cleaner cover or where it's mounted to the plenum.
All these parts have a gasket of some sort and they can be dislodged,missing,torn or just plane bad.

No that is not normal. I would say you have a small leak somewhere or a float in one of the carbs is out of wack. Easiest is to check for a leak somewhere. Pulling the carbs is a choir....
Enjoy the ride. They are all good, just some better than others.

I was afraid it was NOT normal. The gas smell lasts only a minute or so after shutting down which makes sniffing it out very difficult. All the hoses are new but I will recheck them before pulling the carbs again.

Thanks for all the continued help as I try to breathe new life back into this old bike.

New hoses are great,IF you also used new clamps...the real kind...It's most important there used at the outlet of the pump and the carb,there's 4 psi of fuel pressure there.

Just came in from a ride. Gas smell was vague but present. Absolutely no leaks. Smell seems to be coming from the carb vents.

Shut the fuel off 30 seconds before shutting down engine. If the gas smell is no longer present you for sure have a leak somewhere downstream. Bike upright on center stand. Confirm fuel valve operation prior that it is working and will run out of fuel.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

Found the leak . . . finally. Due to trash in the fuel pump I installed a Mr Gasket filter between the pump and the carbs. The filter was SEEPING as such a slow rate it was literally evaporating without leaving a trace. It wasn't until the motor was cold that the gas could actually felt instead of smelled. Removed the filter, installed a new hose, all is good in WingWorld.

Thanks for all your help.
