Air box removed main jet should go up?

Hello, my problem is the bike wouldn’t run with the box cover so removed it, I should have to go up on the jet size I believe correct? What is stock main jet? Thank you

The bike wasn’t running right when the air box was on so we removed the top seal cover. Now I see a lot of people saying you need to move a size up in jet size? Anyone know this size? Thank you.

up 2 sizes and plug chop to confirm, then adjust accordingly
