    Default 2007 fn2 valve clearance guide / specs?

    Anyone have a valve clearance guide with correct specs measurements from a honda service manual for the FN2 please?
    Diagrams from the book with cylinder order to adjust them in etc

    Thanks

    Hopefully this will give you more of an idea

    Cylinder Head Valve Clearance Adjustment

    Special Tools Required

    Tappet adjust wrench set
    07MAA-PR70100





    NOTE: Adjust the valves only when the cylinder head temperature is less than 38 C (100 F).



    1 - Remove the cylinder head cover.

    2 - Set the No. 1 piston at top dead center (TDC). The punch mark (A) on the variable valve timing control (VTC) actuator and the punch mark (B) on the exhaust camshaft sprocket should be at the top. Align the TDC marks (C) on the VTC actuator and exhaust camshaft sprocket.





    3 - Select the correct thickness feeler gauge for the valves you're going to check.

    Valve Clearance

    Intake: 0.21−0.25 mm (0.008−0.010 in.)

    Exhaust: 0.25−0.29 mm (0.010−0.011 in.)





    EXHAUST v (1 - 4)



    INTAKE ^ (1 - 4)






    4 - Insert the feeler gauge (A) between the adjusting screw (B) and the end of the valve stem, and slide it back and forth; you should feel a slight amount of drag.





    5 - If you feel too much or too little drag, loosen the locknut with the special tools, and turn the adjusting screw until the drag on the feeler gauge is correct.

    6 - Tighten the locknut to 20 Nm (2.0 kgfm, 14 lbfft), and recheck the clearance. Repeat the adjustment if necessary.





    7 - Rotate the crankshaft 180 clockwise (camshaft pulley turns 90 ).

    8 - Check and, if necessary, adjust the valve clearance on No. 3 cylinder.





    9 - Rotate the crankshaft 180 clockwise (camshaft pulley turns 90 ).

    10 - Check and, if necessary, adjust the valve clearance on No. 4 cylinder.





    11 - Rotate the crankshaft 180 clockwise (camshaft pulley turns 90 ).

    12 - Check and, if necessary, adjust the valve clearance on No. 2 cylinder.

    13 - Install the cylinder head cover.

    Once you have selected the year & model and then the folder you want to look in, click on the Search button, top left and the details will appear in the Result window on the right.

    So long since i looked at it i forgot this
