Exhaust camshaft 1
Intake camshaft 2
Installation steps:
Turn the crankshaft counterclockwise with
a wrench.
NOTE:
Squeezing the decompression lever allows
the crankshaft to be turned easily.
Align the T.D.C. mark a on the rotor with
the align mark b on the crankcase cover
when piston is at T.D.C. on compression
stroke.
Fit the timing chain 3 onto both camshaft
sprockets and install the camshafts on the
cylinder head.

The camshafts should be installed onto the
cylinder head so that the punch mark c on

the cylinder head surface, as shown in the
illustration.
