CHECKING THE CAMSHAFT
• Camshaft sprocket "1"
Wear/damage → Replace the
camshaft assembly and timing
chain as a set.
• Decompression system
a. Check that the decompression
mechanism cam "1" moves
b. Check that the decompression
mechanism cam lever pin "2"

CHECKING THE TIMING CHAIN
• While pressing the tensioner rod
lightly with fingers, use a thin
screwdriver "1" and wind the ten-
sioner rod up fully clockwise.
• When releasing the screwdriver

• Apply the engine oil on the decom-
b. 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.
c. 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 exhaust cam-
shaft and the punch mark "d" on the
intake camshaft must align with the
cylinder head surface, as shown in
