CAUTION
Examine the position of the cam tim
ing marks for each cylinder before re
moving the engine. When a cylinder is
set to TDC on the compression stroke,
the timing mark on the cam sprocket
(rear cylinder) or cam sprocket plate
(front cylinder) may not precisely
align with the pointer on the cylinder
head. Make a drawing of each cam
sprocket (or cam sprocket plate) and
cylinder head pointer so the cam
shafts can be correctly timed during
assembly. Refer to Cylinder Head Re-
moval in Chapter Four for checking
the cam timing.
