ADJUSTER INSTALLATION
Install the camshaft and cam chain tension in the reverse order

CAMSHAFT (AUTOMATIC DECOMP.)
• Place a wrench over the crankshaft and turn it counter-clock-
wise to align the TDC mark A with the center of the groove B
of the timing inspection hole.
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 TDC mark A with the index mark B and hold
this position when installing the camshafts.
• Just before installing the camshaft into the cylinder head,
apply engine oil to the camshaft journals, camshaft journal
holder, camshaft bearings and cam faces.
