Guys put a polo 15 in windshield on and noticing more fumes I relocated the fuel tank vent hose under the pod got rid of the gas odor I noticed a lot more exhaust fumes lingering riding in a pack any one else observe this?

The wind shield is probably just collecting the fumes just like a van or high profile vehicle collects air behind it. As the air containing the exhaust fumes pass over and to the side of the windshield, they will swirl around and can get trapped behind it. Without the windshield the fumes just blow right past you.

You can stay back a little further away from the machines in front of you.
Or vent the windshield to relieve the vacuum created by the windshield.
