1 . Rotate the crankshaft until the dot on the cam
chain drive sprocket is aligned with the crankcase
projection (dot facing downward).
2. Align the single plated link on the cam chain with
the dotted tooth of the cam chain drive sprocket.
Use a wire to pull the chain up through the cylinder

aligning the two plated links on the chain with the
two dots on the sprocket.

242 to the cam sprocket bolts and torque to
specifications.
