This section describes cylinder head, valves, 
camshaft and the other parts maintenance.

The engine must be removed from the 
frame to service cylinder head. 

 

•

 

Camshaft lubrication oil is fed to the 
cylinder head through an oil orifice in the 
engine case. 

 

•

 

Before installing the cylinder head, make 
sure the orifice is not clogged and the 
gasket, O-ring, and dowel pins are in 
place.
