Why do I smell gas every time I hit a bump in the road?

I don't smell gas when hitting a small bump in the road but there is no small bumps on PA roads. Happens every time I hit one. Gas isn't in the air cleaner. I'm thinking carb float level. Any thoughts?

Check ur tank mounts. I had a back one crack and eventually started leaking onto the rocker covers.....jmo

Ride her down the road when you smell gas pull over look for gas coming out of the float vent line.If no gas there check your gas cap vent.Most of the time when float level is to high it will run rich and stall. Also check your shut off valve for leaks.

:oldconfused: Isn't it gonna come out the vent line or overflow line?

Still trying to find the gasoline smell, It might be getting worse. A friend riding behind me can smell it also. I have stopped when it happens and crawled all around the bike and can't find anything. Could it be coming out of the exhaust somehow?

I get the same gas smell and always thought it was because my cap vent was removed. Did you check the tank mounts as suggested?

Say you leave the petcock on, the bike is on the side stand, it sits overnight:
1. There is no [gas] puddle on the ground.
2. Nor is the oil thinned out and runs off the dipstick like water.
3. Nor is the oil level excessively high and smells like gas.
This sort of rules out the float level.

Say the seasons change and oh shit is my crotch is soaked, and my 100% cotton briefs are stuck to me skin like crazy glue. And say that bump up ahead is where my nuts fly up and land in any other season, but that sun beats down on my bike's gas tank; where me little gas cap's piss hole is choo-choo-inn some hot vapor out the cap; my rider behind me smells the vapor whip around me waist, while I get a taste full on me upper lip.
This sort of rules out spring/fall/winter.

How close am I?

None of the above. Also checked the mounts.
