Remove the cylinder head cover.
Turn the cooling fan clockwise until the mark of the timing drive sprocket on the camshaft is at the
top, dead center, and the "T" symbol (or other mark) of the magneto flywheel aligns to the crankcase
mark.
When adjusting, loosen the lock nuts, adjust the bolts with
a valve-adjusting wrench when turned clockwise the valve
clearance decreases. And when turned counterclockwise
the valve clearance increases. Put a feeler gauge with specific
sizes between the valve and rocket to check for correct
clearance.
Take out the feeler gauge, tighten the lock nuts, and then inspect the valve clearance again.
Valve Clearance 0.08 ~ 0.12mm
Inspection and adjustment should be done in
cool conditions (below 35oC).
The crankshaft should corotate, or the exhaust port may not be adjusted.
