Strong fuel odor.

The last couple of rides I have noticed a very strong raw fuel odor on my 2014 700. It is most noticeable on rough terrain or on inclines. I don’t notice it when it’s just sitting still and running. I don’t see any fuel leaks anywhere without pulling the plastics off. If I open the fuel cap door and smell in that area it’s very noticeable. My son n law was riding behind me and could smell fuel he did not know if it was his 09 700 or coming from mine. Is this just normal venting? I’m not sure where the tank vents or if it vents from the cap. Anyone else notice this on their Grizz? Any suggestions as to what to check would be appreciated. Like I said just sitting there and running or not there is no smell. Thanks
