Ok I need to replace the little washer for the little bolt underneath the mesh filter. I thought at first I need to drain out all my oil. However when I had my bike on the sidestand I noticed in the oil sightglass that the oil barely shows. This got me thinking that maybe I can remove the little mesh filter bolt without draining oil. I'm figuring the oil will be on the left side of the bike enough so that I won't have it all drain out the mesh filter plug or the mesh filter. Thoughts?
