OIL HOSE ROUTING
GENERAL
See Figure 3-38. The oil tank has four hoses. The drain hose
(2) attaches to a fitting on the left side of the frame. From the
top of the tank, the vent hose (3) and the return hose (4) join
the bottom feed hose (1) near the battery tray. Cable straps
secure the hoses in place.
See Figure 3-39. The feed (1) and return hoses (3) run
together between the swingarm mount block and crankcase,
beneath the engine and forward to the oil pump. The feed
hose attaches to the rear most oil pump fitting; the return
hose connects forward and above.
After diverging from the feed and return hoses, the vent hose
is routed beneath the starter. The vent hose continues on to
the right side of the motorcycle and goes behind the gearcase
cover assembly where it connects to an elbow fitting.
