Suzuki Ozark - VALVE CLEARANCE

PERIODIC MAINTENANCE 2-5
VALVE CLEARANCE
Excessive valve clearance results in valve noise and insufficient
valve clearance results in valve damage and reduced power.
Check the intake and exhaust valve clearances at the distances
indicated above and adjust the valve clearances to specification,
if necessary.
• Remove the fuel tank. (5-3)
• Remove the TDC plug 1.
• Remove the valve inspection caps.
• Remove the spark plug. (2-6)
NOTE:
Valve clearance is to be checked when the engine is cold.
The intake and exhaust valves must be checked and adjusted
when the piston is at Top-Dead-Center (TDC) of the compres-
sion stroke.
• Turn the crankshaft until the piston reaches TDC on the com-
pression stroke by turning the recoil starter 2. Turn the recoil
starter 2 until the line 3 on the generator rotor is aligned with
the mark 4 on the crankcase.
NOTE:
The crankshaft can be turned to align the line 3 and mark 4 by
slowly pulling the recoil starter lope without removing the ricoil
starter.
• Insert the thickness gauge to check the clearance between
the valve stem end and the adjusting screw on the rocker
arm.
 Valve clearance (when cold)
IN: 0.03 – 0.08 mm (0.001 – 0.003 in)
EX: 0.08 – 0.13 mm (0.003 – 0.005 in)
 09900-20803: Thickness gauge
• If the clearance is out of specification, bring it into the speci-
fied range using the special tool.
 Valve clearance adjuster locknut:
14 N·m (1.4 kgf-m, 10.0 lb-ft)
Inspect initially at 1 month and every 6 months there-
after.
