I define "revolutions" as flywheel revolutions, NOT circuit breaker cam revolutions. To get flywheel revolutions, I multiplied circuit breaker cam revolutions x 2 (crankshaft turns 2 revs per 1 rev of the circuit cam). Using my non-scientific method of video taping the circuit breaker cam on my 1971 XLCH 900 motor and using the 225 lbs in this old body..... I can report I saw: \\ - Pushing very slowly on the kick pedal by hand (spark plugs removed), there was almost, but not quite 1 complete flywheel revolution. - Using foot on the kick pedal (spark plugs removed), app. 2-3/4 flywheel revolutions. - Using foot on the kick pedal (spark plugs installed), almost exactly 2 flywheel revolutions. \\ More or less, this equates to one compression stroke, per cylinder, per kick, (at least on my bike). \\ **Note**: The original videos were recorded at normal speed using 60fps. If needed, you can reduce the playback speed to aid in your viewing of the number of revolutions. \\ |{{ :video:100-starter_slow_kick_thru_via_hand_-_just_under_1_complete_revolution_by_the_doctor71.mp4 |}}|{{ :video:100-starter_kick_thru_without_spark_plugs_-_1_kick_-_almost_3_revolutions_by_the_doctor71.mp4 |}}|{{ :video:100-starter_kick_thru_w_spark_plugs_installed_-_2_revolutions_by_the_doctor71.mp4 |}}| | 1.
