Oil Hoses
Install new oil hoses whenever the old hoses become
hard and brittle. When replacing damaged or worn oil
hoses, make sure to install the correct transparent hoses of
the correct diameter. Non-transparent hoses do not allow
the rider to visually inspect the hoses for air pockets or
other blockage that could cause engine seizure. When at-
taching hoses, secure each hose end with a clamp.
Check Valves
Two check valves are used in line with the oil hoses
(Figure 6). The arrow on the check valve body must point
in the direction of normal oil flow.
