It's a exhaust smell not gasoline, unless what your meaning it's making the bike run richer? I will be replacing the intake boots under the carbs, they have cracks but I don't believe they are all the way through, squirted some starting fluid on them while the bike was running and the engine did not speed up.
I picked up a set of fishtail slip-ons I will first install them and see if it helps, if not I will put the original real tall windshield on. It is not an issue with the 5" tall shield cause all you get is wind.
