subject: Gas leak from the gas cap left brownish stuff on the tank
I am looking for some feedback and to see if any riders having the same problem.
Bought a 2006 Nomad a week ago and have ridden 300 miles so far. I noticed a few hours later ( I think) after coming home from riding, several brownish stuff (waterly or oily substance) formed near the cap on the right side of the tank. It happened a several times already and I did not know the source of this and what that was.
To find the source of this substance, yesterday I placed a white tissue paper around the gas cap along the circular groove line and discovered this morning that the brownish stuff soaked ( a little bit but enought amount to make me concern) the tissue and it smells like gas.
Now I know this is from the gas cap. But what is this brown stuff smelling like gas?
I understand that there should be normal gas vent in the event of over heating of gas in the gas tank. However If this was a normal gas vent, there should be no residue like this formed on the tissue or on the surface of the tank because the gas should evaporate right away.
Does anyone know what this brown stuff is?
Thank you in advance!
