SERVICE INFORMATION
@
Camshaft lubricating oil is fed from the oil filter t o the front bearing through an oil control orifice located in the engine
case, and t o the rear bearing through an oil control orifice in the camshaft rear holder.
Be sure these orifices are not clogged and that the 0-rings and dowel pins are in place before assembling the engine.
*
Before assembling the camshaft, lubricate the bearings with engine oil and pour 100cc (3.38 oz) of engine oil into the engine
case oil pockets to provide initial lubrication.
