Install the camshaft sprocket onto the camshaft so the camshaft sprocket boss
fits into the appropriate hole on the camshaft sprocket. Make sure the camshaft
sprocket boss is facing up so it is visible above the edge of the cylinder head as
shown. Align the horizontal marks on the camshaft sprocket with the top edge of
the cylinder head as shown. Fit the camchain over the camshaft sprocket.
For correct engine timing the marks on the camshaft sprocket must be even with
the cylinder head mating surface at the same time the "T" mark is lined up with
the with the index notch in the timing inspection hole. The camshaft lobes should
be facing down and their should be slack in the rocker arms.
Apply a small amount of blue Loctite (non-permanent) to the threads of the
camshaft sprocket bolts. Thread in the camshaft sprocket bolts and tighten to
specification using a 5 mm Allen socket.
