Good day everyone. My machines running awesome I've always wondered about the compression though. It's always been 160 to 170 PSI both cylinders with multiple gauges. I don't know the history I'm assuming it's a stock motor. Just trying to figure out if I should be running premium fuel. Maybe that means the head's been cut a little bit or something? Let me know your thoughts! @mikidymac
