The bike runs adequately but not sharp below 7500rpm. Mimics a tired plug or two. Runs great on top. This stops when the valve closes. The bike has lackluster throttle response, and does not run very well anywhere.
Top end is weak.
PV system is non-functional and has come to rest in half open position. AEC Setup Let's assume a few things first. The bike's together, in running order, with the lowers and belly pan removed. Start the motor. As you bring the revs up past 7500rpm, the pulley should snap 100 degrees clockwise, closing the valves.
