SERVICE INFORMATION
GENERAL INSTRUCTIONS
Camshaft, rocker arm shaft and rocker arm can be serviced with the
engine installed on the frame.
Camshaft lubrication oil is fed to the cylinder head through an oil
control orifice in the engine case.
Be sure this orifice is not clogged and the O-ring and dowel pins are in
place before installing the cylinder head.
During assembly, apply molybdenum disulfide grease to the camshaft
bearings, and pour clean engine oil into the cylinder head.
