The vacuum shutoff valve,just in front of the fuel cap....It has a weep hole in the bottom of it.
All it takes is a drop or two to be able to smell it and it will evaporate quick.
Well mine did this... :)
Also,on my 88,the carb vent tubes are open ended in a metal pipe just in front/left of that valve.
Some vapors may be coming from there too.I think it is contained in all other years but 88 and 89.

moisture or staining in the tray by the fuel filler neck is an indication of a leaky vacuum cutoff petcock...also check the gasket on the fuel cap, those are cheap to replace...

After a ride the fuel tank sitting directly above the hot engine causes the fuel to expand and vapors are forced out of the tank...Low fuel levels will exasperate the problem however it can happen anytime...some fill the tank with cool fuel before parking and other leave the bike outside until it cools off to offset this problem...Some days I can hear mine venting as it sighs and sings as the pressure releases...

Out of the three wings I have owned I havegotten used to a slight smell of fuel, but always have it in theback of my mind that if the fumes get too bad, start checking before I am riding a molotov cocktail.

Wild guess here, but check the hose that goes from the fuel cap to the evap cannister.
My cannister fell off tonight as I was leaving the parking lot at work. The only thing holding it to the bike was the hose from fuel cap. I cut the hose and removed the cannister to get home and smelled that raw gas odor when I parked it in the garage. That's the first time I recall smelling it. Well, second time. First was when the aformentioned vacume shutoff valve was leaking into the tray by the filler neck last year.
