MAINTENANCE
Oil Pump Adjustment Procedure - 250 Engines
1. Before adjusting the oil
pump, check engine idle
RPM and carburetor ad-
justments which are found
in the owner’s manual sup-
plement.
2. Loosen throttle cable jam
nut and turn adjuster in or
out until there is 1/16″ -
1/8″ (.16 - .32 cm) of
throttle lever travel before
throttle slide starts to open.
See Owner’s Manual Sup-
plement.
3. Place very slight pressure
on the throttle lever until all
freeplay is removed from
throttle cable (to the point
where the carb slide is just
starting to rise).
4. Loosen locknut. Turn ad-
juster in or out until all free-
play is removed from oil
pump cable (the point
where the oil pump arm is
just starting to move off of
its stop). The pump stop
keeps the pump arm from
rotating any farther down
than the idle position so no
visual alignment of marks
is necessary. Tighten the
locknut
