I took my bike out of winter storage recently to go riding on a somewhat hot day (81 degrees F). Engine temp stayed mainly in the 199-216 range throughout the ride. It was a one hour ride round trip. That is a very normal ride for me last season. After getting back to the house, I moved it into the garage while it was still hot. As I was getting ready to tuck it away, I started smelling gasoline.

I've had the bike for a year now and it has never smelled like gas after a ride. When I asked the dealer about this, I was told to vent out the garage and see if the problem persists. Dealer asked questions about exposure to heat (does it sit in the sun? no). Reason for their questions is that the gas caps are built to release pressure from heat so it can smell like gas on hot days or after rides. What I find strange about the explanation is that this hasn't ever happened with this bike before.

Anyone else experience this?

When hot and especially on a hot day fuel vapours will exit via the tank overflows, If it was me I'd lift the tank and check connections including the breather/overflow just to be sure.

I've noticed that if I don't fill the tank after a fairly long ride I get gas fumes in my garage. It's not super strong but it's there. If I fill the bike up right before I get home I don't get any smell at all.

Did you remove your charcoal cannister?

I have not. Does removing it help with the gas smell?

Be careful when lifting the tank, the fuel line can be short enough to brake the nipple without knowing.

Not at all, it will make it worse because the tank vents to the open air now under your bike. I took mine off and get a gas smell but it’s not bad or anything. If you overfill your tank gas will get in the charcoal cannister, this can make it hard to start as well. I know because I did it 😬

After venting out the garage the gas smell went away and didn't seem to return. I went on two rides today. Weather this time around was a bit cooler (77 degrees F). After both rides, I sniffed around the bike and didn't smell any traces of gas.

Perhaps the recent prevalence of gas smell was due to a long, hot ride right out of winter storage. Or there's a chance I overfilled the gas tank before I put it away for winter. I'll continue to monitor it.

I had a similar issue on my 899, turned out to be the fuel pump gasket located under the tank

I went on a few 88 degree ambient temp rides, which is hotter than my first ride out of winter storage. I haven't smelled any gas since that first ride. Just based on the patterns so far, I don't think I have any gasket leaks or loose fuel lines. Not sure if heat + fuel vapor is an explanation anymore, leaving a potentially overfilled gas tank as the likely cause?
