CAMSHAFT
• Turn the crankshaft clockwise with the box wrench and align the
line A on the starter clutch with the index mark B of the valve
timing inspection hole while keeping the cam chain pulled up-
ward.
#
Pull the cam chain upward, or the chain will be caught
between crankcase and cam drive sprocket.
#
To adjust the camshaft timing correctly, be sure to align
the line A with the index mark B and hold this position
when installing the camshafts.
• The cam shafts are identified by the embossed letters.
• Before replacing the camshafts on cylinder head, apply molyb-
denum oil solution to their journals and cam faces.
• Apply engine oil to the camshaft journal holders.

NOTE:
Before installing the camshaft, check that the tappets are installed
correctly.
• Pull the cam chain lightly.
• The exhaust camshaft sprocket has an arrow marked "1" A.
Turn the exhaust camshaft so that the arrow is aligned with the
gasket surface of the cylinder head.
• Engage the cam chain with the exhaust camshaft sprocket.
• Bind the cam chain and the sprocket with a proper wire clamp
1 to prevent the cam chain disengagement while installing the
camshaft journal holders.
• The other arrow marked "2" B should now be pointing straight
up. Starting from the roller pin that is directly above the arrow
marked "2" B, count out 14 roller pins (from the exhaust cam-
shaft side going towards the intake camshaft side).
