Check and adjust valve/tappet clearance procedure:
1. Remove the timing inspection plug; then remove the tappet covers and spark plug.
2. Rotate the crankshaft to the TDC position on the compression stroke.
NOTE: At this point, the rocker arms and adjuster screws must not have pressure on them.
3. Align the timing mark to the magneto cover mark.

Adjustment Procedure:
A. Place Valve Clearance Adjuster onto the jam nut securing the tappet adjuster screw; then rotate the valve adjuster dial clockwise until the end is seated in the tappet adjuster screw.
B. While holding the valve adjuster dial in place, use the valve adjuster handle and loosen the jam nut; then rotate the tappet adjuster screw clockwise until friction is felt.
C. Align the valve adjuster handle with one of the marks on the valve adjuster dial.
D. While holding the valve adjuster handle in place, rotate the valve adjuster dial counterclockwise until proper valve/tappet clearance is attained.
NOTE: Rotating the valve adjuster dial counter-clockwise will open the valve/tappet clearance by 0.05mm (0.002 in.) per mark.
E. While holding the adjuster dial at the proper clearance setting, tighten the jam nut securely with the valve adjuster handle.

Country Cat is an Arctic Cat, E-Z-GO, Kawasaki, and Textron off Road dealer that opened it's doors in November 1991.  We started small and over the years have grown to become one of the largest powersports dealers in the United States.  We believe this success has been attributed to living by the motto: "Commitment to Service, Passion for Excellence."
