This is common on a lot of engines. Not just boxers. The reason I was told when talking with a Yamaha district service rep is they don't have to account for gasket thickness in their tolerances. I'm sure there are more seasons then that. Another issue with the FA20 is the screen in the pickup tube is in the top of it, trapping everything inside the tube.
