1. Insert the intake and exhaust valves in the head, and measure valve stem installed height (A). Intake Valve Stem Installed Height
   Standard (New): | 40.2−40.4 mm (1.58−1.59 in.)
   Exhaust Valve Stem Installed Height
   Standard (New): | 40.2−40.4 mm (1.58−1.59 in.)
If valve stem installed height is over the standard, replace the valve and recheck. If it is still over the standard, replace the cylinder head; the valve seat in the head is too deep. |
