Valve adjustments to the honda engine are recommended for preventive maintenance. Below is the basic guide to adjusting your valves.

Please Note: after doing cylinder 1 you do NOT need to turn the crank 180 degrees to set cylinder 4 and so on.
___________________________________________________________________
 
Engine firing order:
Note cylinder one is passenger side front towards crank. Cylinder 4 is drivers side front.
 
 
NOTE: Adjust the valves only when the cylinder head temperature is less than 100 ºF (38 ºC).

Remove the cylinder head covers.

Set the No. 1 piston at top dead center (TDC).

Align the pointer (A) on the front upper cover with the No. 1 piston TDC mark (B) on the front camshaft pulley
 
 
 
Select the correct thickness feeler gauge for the valves you're going to check.



Valve Clearance
Intake:
0.20-0.24 mm (0.008-0.009 in.)

Exhaust:
0.28-0.32 mm (0.011-0.013 in.)
 
 
You will be adjusting intake and the exhaust valves. Insert the feeler gauge (A) between the adjusting screw and the end of the valve stem on No. 1 cylinder, and slide it back and forth; you should feel a slight amount of drag.
 
 
Rotate the crankshaft clockwise. Align the pointer (A) on the front upper cover with the No. 4 piston TDC mark (B) on the front camshaft pulley. You will no longer be aligning the crank pulley.

Check and, if necessary, adjust the valve clearance on No. 4 cylinder.
 
 
Rotate the crankshaft clockwise. Align the pointer (A) on the front upper cover with the No. 2 piston TDC mark (B) on the front camshaft pulley.

Check and, if necessary, adjust the valve clearance on No. 2 cylinder.
 
Rotate the crankshaft clockwise. Align the pointer (A) on the front upper cover with the No. 5 piston TDC mark (B) on the front camshaft pulley.

Check and, if necessary, adjust the valve clearance on No. 5 cylinder
 
Rotate the crankshaft clockwise. Align the pointer (A) on the front upper cover with the No. 3 piston TDC mark (B) on the front camshaft pulley.

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