While troubleshooting a top end power reduction, I'm only coming up with 95 psi on a compression test (hot engine, throttle wide open, battery up and cranking fast). Later, I decided to test the ignition timing and was shocked at the amount of blow by coming out of the hole you check timing at. I assume this is where all my compression is going - nowhere. How much airflow should you get with this timing plug out and the engine idling? The bike will not idle but only for a few seconds with the plug out.
