Servicing Your Honda
Measure the decompressor arm clearance by
inserting a feeler gauge (1) between the
decompressor arm adjusting screw (6) and right
side rocker arm (7).
(1) feeler gauge
(6) decompressor arm adjusting screw
(7) right side rocker arm
DECOMPRESSOR CLEARANCE:
RIGHT EXHAUST VALVE CLEARANCE
+
0.014 IN (0.35 mm)
Example:
If measured right exhaust valve clearance is
0.011 in (0.28 mm), decompressor clearance is:
0.011 in (0.28 mm) + 0.014 in (0.35 mm)
= 0.025 in (0.63 mm)
If only decompressor arm clearance needs
adjustment, see
Decompressor Arm clearance
Adjustment (page 73).
