5) Holding the hexagonal part of both the intake and exhaust
camshafts with the wrench or equivalent tool as shown,
align the “ ” mark on the exhaust camshaft sprocket with
the “ ” mark on the intake camshaft sprocket. (The No.1
piston is at the top dead center of its compression stroke.)
6) Check that the punch mark on the intake camshaft sprocket
and the punch mark on the exhaust camshaft sprocket are
in the position shown.
7) Holding the No.1 cylinder at the top dead center of its
compression stroke and the punch marks in alignment as
described in step 5, align each punch mark on the intake
and exhaust camshaft sprockets with the mid point of the
corresponding color plates (2 places) of the cam chain, and
install the cam chain.
• Turn the intake camshaft and the exhaust camshaft while
holding the hexagonal part of the intake and exhaust
camshafts with the wrench or equivalent tool and thereby
aligning the alignment marks on both the intake and
exhaust camshaft sprockets.
• Install the cam chain aligning the mid point of the two
color plates with the punch mark on the intake/exhaust
camshaft sprockets.
• Check that the color plate (one) of the crankshaft sprocket
is not out of alignment.
• After installing the cam chain, check that the crankshaft
sprocket and the camshaft sprocket are in alignment with
the No.1 piston at the top dead center of its compression
stroke.
