3-2. LUBRICATION
Table 3-1. Recommended Oil Lubrication Chart
Nothing affects the performance and durability of your engine more than the lube oil used. If an inferior oil is
used, or the oil is not changed regularly, the risk of piston seizure, piston ring sticking, and accelerated wear
increases significantly. Engine life may be seriously shortened.
This engine adopts a forced oil lubrication system driven by a trochoid pump. Lubricating oil is circulated as fol-
lows: lubricating oil filter, trochoid pump, crankshaft <flat metal>, crankpin bearing insert. The rocker arm cham-
ber is lubricated by lube oil vapors.
