Is your vacuum petcock leaking? Forward of gas cap, would be stained in overflow tray below the petcock and probably covered with dust.
If so there's a rebuild kit for it at cyclemax.

I've also found a leaking fuel suppy line between the fuel pump and gas filter.
Have you changed the gas filter this year?

Are you talking specifically about raw gasoline smell, or a rather strong exhaust fume smell ? My wife use to, and under certain conditions, still does complain about the exhaust smell of our '97. I think that strong exhaust smell is just typical of a carbureted engine, with no catalytics to clean it up. A bike is a bit different from a car reagrding your exposure to those smells. The pipes are right under you, and in confined spaces, or with the wind blowing the right way, it does smell. She got used to it. I don't think it's an engine issue, as the bike has always run great, and gets good to great gas mileage, compared to others on this forum. 35 - 45 mpg depending on 1 up/2 up, city/highway, 55/70 mph, etc. I know if I am sitting near the exhaust while it's running, or the pipes are pointing into the garage, I'll hear about it.

I'm having same issue with 96 SE, after removing a lot above the carbs, it appears that the leak is near base/between the carbs. Does not look like much is leaking, just moist. Tomorrow going to use inspection mirror to see if I can see exactly it is coming from.
The smell goes away after the bike sits a few days. Crank it up and let it run a few minutes and back again.
I was afraid it was a "dripping leak" that would be a fire danger.

Check that the exhaust stud nuts are snug/torqued properly, loose and you can get exhaust smells. They get loose from lifting the bike on m/c jack or just with time, vibration loosens the nuts.

Good carb rebuild hints in this video





Possibly loose philips screws on the rubber intake couplers, use 18" long screw driver. They loosen with time.
Or leaking from dirty carburetors/ float valves dirty with piece of junk not allowing float valve seat to close fuel flow into bowls/ overflowing and leaking out.

The boot clamps being loose is a very good possibility BUT, how do I get to them to tighten them, Cant even see the screws.
Insight would be very much appreciated.
Rebuilding the carbs would not be an issue, have done to many many carbs 100s of times, just gaining access to these is a bitch!

Remove the inner fairing on each side and shine a flashlight in there. You'll see the clamps on the insulators.

Problem solved!
Not sure how though???
I did find the mounting clamps screws, 3 of four a little lose, tightened them. Still had some smell, but seemed to dissipate quicker.
Rode today, NO smell while or after riding. Bike had not been ridden for 2+ months prior to having the issue. I suspected something may have dried out (shrunk).
Anyway, THANKS FOR ALL THE INPUT!!!!!
