I have a 2020 Onward with about 30 hours on the motor. Fouled the first spark plug around 20 hours and had to replace it. This one is still running ok for now, but I just found something that I'm curious about. On the Air filter cap there's a Rubber valve covering the inlet tube. Anyone know why the heck this thing would be on here restricting air flow?

I just wonder if maybe this has something to do with fouling spark plugs. Maybe the computer can't adjust the mixture enough to compensate for the restricted air flow? I just took mine off and will see how it runs for a while.

Edit* I found the second inlet hole on the bottom side of the air box. Definitely not the problem.
