The way I manage to keep it from doing it is to fill it on the sidestand, only to where it barely kisses the bottom of the filler tube, then stand the bike upright to put the cap on. Sometimes if you rock it side to side very slightly, you can see a bubble get released and the level equalize a bit.
ok i will pay attention and try that next time.
