VALVE CLEARANCE ADJUSTMENTS
Check and Adjust the valve clearance when the engine is cold or when the
engine temperature is below 35°C.
Check that the spring compressor device for ignition has a clearance.
Remove the seat.
Remove the fuel tank.
Remove the lid of the timing system on the left side of the engine (fig. 35).
Remove the ignition coil.
Remove the two small lids of the camshafts.
Turn the flywheel so that the reference marks on the gears of the camshafts
are lined up with those on the engine guard and the piston is at TMC (fig. 36).
Check the clearance of all four valves by inserting feeler gauges between the
camshafts and the rocker arm (fig. 37).
Valve clearance: Intake valve 0.05 mm
Exhaust valve 0.10 mm
To set clearance, loosen the lock nut and turn the adjusting screw to get a
slight drag on the feeler gauge.
Hold screw steady and tighten the lock nut with appropriate tool 19.1.20522
