Valve Clearance: Specifications

The valve clearance on a cold engine (approximately 20 degree C) should be: 

Inlet valve:.......................................................................................................................................................................................................0.20 ± 0.03 mm
Exhaust valve:..................................................................................................................................................................................................0.40 ± 0.03 mm

NOTE:  The tolerances are less at setting. When checking the valve clearance through the plug hole the tolerances are larger.

Differences in valve clearance for different engines/ambient temperatures: 
- 0.01 mm at 15 degree C
+ 0.01 mm at 25 degree C
+ 0.02 mm at 30 degree C
