I just got a compression tester and my bike has a reading of 200 psi with the throttle open and a cold test it feels a bit sluggish so I'm looking into checking valve clearances, from memory the manual says 175 psi is standard so I'm wondering how is mine 200 psi. My tester has schrader valves in the hose at the spark plug end so it's not using the hose as part of the reading
