Like Docc said. Be sure you know what you are plugging. One line from the tank is draining rainwater and/or gas overflow. Another is to let air back in the tank as the fuel is used. I wouldn't want to accidentally plug either of those.
Ah, who needs one? I heard those high cam engines have nothing but valve train problems. Now, if there was an MGS-01 body kit for V11s, that would be different...
