CYLINDER HEAD/VALVE

The timing marks on the cam sprocket must be
flush with the cylinder head surface and make sure
the rear end cam lobe is facing outward (TDC on
exhaust stroke).
If the rear end cam lobe is facing inward (TDC on
compression stroke), rotate the crankshaft counter-
clockwise 360
°
(one full turn) so the rear end cam
lobe faces out.
Do not forcibly
remove the dowel
pins from the cam-
shaft holder.
Loosen the camshaft holder bolts in a crisscross
pattern in several steps from the outside to inside
to prevent damaging the camshaft holder and
camshaft.
Remove the camshaft holder.
Remove the cam chain off the cam sprocket, being
careful not to damage the cylinder head and cam-
shaft and then remove the camshaft.
Be careful not to
jam the removed
cam chain into the
timing sprocket of
the crankshaft
when rotating the
crankshaft.
Rotate the crankshaft counterclockwise 360
°
(one
full turn) and align the 1.2TF mark on the ignition
pulse generator rotor with the index mark in the
front crankcase cover.
Be sure that the timing marks on the cam sprocket
of other camshaft are flush with the cylinder head
surface and that the rear end cam lobe is facing
outward (TDC on exhaust stroke).
