Any suggestions on how to verify, while stationary, the operation of the servomotor that opens the power valves? Suspecting problems with the servomotor but because you need 7000 RPM to activate and open, not sure how to verify in the garage. I had a suggestion to lift/jack the machine, nail the throttle to achive 700 RPM, and visually monitor the movement. Nervious about running 7000+RPM on a free running track like that. Any feedback?.
