As part of engine testing, I ran the Rotax engine at 3,500 RPM for 5 mins three different times. Each time I tested the rocker arms to guage the hydralic tappets. At beginning all of them were soft. After third test run, only the intake value/rocker arm in Cyl #1 was not meeting the spec. (virtually no movement when pressed with force on other end of the arm)
