PRE-DELIVERY SERVICE
After the cycle has been uncrated and assembled, the following service and adjustments must be made to
insure proper functioning of the machine:
B/S 90 w/Oil Injection
1. OIL INJECTION: Fill the oil supply tank with a good
grade of 2-cycle oil (for best results use Rockford oil).
Caution: The oil tank must never be allowed to run dry.
Remove the right carburetor side cover and loosen, but
do not remove, the oil supply line at the pump (the
supply line is the rubber line connected at the lower edge
of the pump). With this fitting loosened and the oil tank
filled with oil, oil should flow freely from the fitting. If it
does not, it may be necessary to run your finger along
the oil line while squeezing the line to remove trapped
air. When oil will flow freely from this fitting, retighten the connector bolt but do not overtighten. The
injector pump has a separate gear box and oil filler screw. The gear box oil level should be checked and
corrected as necessary. Remove the plug and fill with a pressure type oil can. On early models the
phillips screw should be replaced with a 5x6 hex bolt for easier removal.
2. CARBURETOR & OIL PUMP CONTROL CABLE
ADJUSTMENTS:
Check and adjust throttle cable at the cable adjusting
screw on the top of the carburetor. If the idle adjusting
screw is turned all the way in, the throttle cable should
be adjusted so that with the throttle closed the outer
cable is moved up and down with- out moving the
throttle valve. (If the idle screw has been adjusted for
proper idle speed, the outer cable should have 1/16 of an
inch of free play).
When the carburetor adjustment has been made, the oil
pump control should be checked and adjusted. With the throttle completely closed, the oil pump outer
cable should have 1/16 of an inch of free play at the oil pump cable stop before it moves the control arm
on the pump from the stop pin. Adjustment is made by the cable adjuster located in the cable by the
transmission oil filter plug.
3. FUEL: On a new cycle, the fuel tank should be filled
with a 20-1 mixture of regular gas and 2- cycle oil
(preferably Rockford oil). This mixture must be used
for the first 250 miles of operation only. Thereafter,
instruct the customer to fill the tank with regular
gasoline only.
4. BATTERY: Fill and charge the battery; follow the
procedure as outlined under Dry Charged Storage
Battery, page 61.
5. TRANSMISSION: Fill the transmission case with 21
oz. of SAE-10W30 motor oil. Transmission level oil is
checked by removing the oil plug located just in front
of the kick starter shaft. Caution: Do not overfill the transmission case.
