The correct valve clearance if critical for the optimum and safe operation of the engine. Minor incorrect value adjustment
will cause poor performance and loss of power. Major incorrect valve adjustment can cause serious damage to the engine.
Therefore, the valve check must be checked regularly.
The inspection and adjustment of the valve clearance should be carried out when the engine is cold. The inspection and
adjustment methods are as follows:
1. Remove the cylinder head cover.
2. Unscrew the viewport cover on the right crankcase cover and use a 14mm socket wrench to turn the crankshaft
clockwise so that the piston reaches the top dead center of the compression stroke (turn the crankshaft until the T
engraved line and the right crankcase cover on the primary drive tooth) The timing mark gap at the edge of the hole
cover is aligned, and the "IN" and "EX" lines of the driven sprocket end of the camshaft are parallel to the cylinder head
cover mounting surface.
3. Insert the standard feeler gauge between the exhaust valve adjustment washer and the exhaust rocker arm to measure
the clearances. The exhaust valve clearance standard is 0.27
±
0.03mm.
4. If the valve clearance is not within the above range, remove the hexagon socket head bolt on the side of the cylinder
head, screw it into the threaded hole of the rocker shaft with M6 long bolt, pull out the rocker arm shaft, make the
valve rocker arm retreat, and then use the suction iron. The rod is sucked out of the adjusting gasket, and the
appropriate valve adjusting gasket is replaced to adjust the valve clearance within the specified range.
5. After adjusting the exhaust valve clearance, continue to rotate the crankshaft 180
°
clockwise. At this time, the
“
IN
”
and
“
EX
”
markings of the camshaft sprocket end face are exactly perpendicular to the cylinder head cover mounting
surface, and then adjust the intake valve in the same way.
6. The intake valve clearance should be 0.16
±
0.03mm. Finally continue to rotate the crankshaft to the timing position to
re-measure the intake and exhaust valve clearance.
7. When all valves are set to the correct clearance, install the hexagon socket screw and tighten the torque 13-17N*m.
8. Reinstall the cylinder head cover, depending on the hole cover.
