Technical Data Preview

Mechanics can reference precise factory measurements directly from the text. Engine compression should read 210–250 psi under full-throttle test conditions. Intake valve clearance is strictly listed at 0.006 in. (0.15 mm) in the cylinder head specifications. When testing the crankshaft position sensor, the magneto pick-up coil resistance must measure 860 ohms ± 10%. Always verify the ATV is properly stabilized on a lift and the ignition is entirely disabled before probing electrical connectors to prevent accidental short circuits or physical injury.
