– Check the valve clearance with the feeler gauge. The minimum
clearance when the engine is cold should be 0.125 – 0.175 mm
(intake) and 0.225 – 0.275 mm (exhaust).
NOTE: if the valve clearance is incorrect for one or more valves, measure
how large the deviation is. Use thinner or thicker compensating washers
depending on whether the valve clearance is too small or too large.
– Dismount the camshafts (see page 4-3) and correct the thickness of
the shims.
NOTE: Shims for the valves are available in the following thicknesses:
2.30 mm, 2.35 mm, 2.40 mm, 2.45 mm, 2.50 mm, 2.55 mm,
2.60 mm, 2.65 mm, 2.70 mm, 2.75 mm, 2.80 mm, 2.85 mm,
2.90 mm, 2.95 mm and 3.00 mm.
– Unscrew the locking bolt, turn the engine to the TDC position of the
front cylinder and lock again(see page 4-5).
– Check the valve clearance of the front cylinder and adjust if
necessary.
NOTE: the procedure for the front cylinder is the same as for the rear
cylinder.
