ENGINE OIL
Engine oil is a major factor in the performance and service
life of the engine. Use the proper grade of oil for the ambient
temperature range anticipated before the next oil change
as shown in the following table.
Notes: Use only API SG or SH rated oil. S&S recommends
regular oil changes every 1,000 miles (1,600 kilometers)
when using petroleum-based oil not specifically formulated
for motorcycles.
CHECKING, ADDING & CHANGING ENGINE OIL
See the motorcycle owner’s manual for information on how
to check, add, and change the oil and filter.
HYDRAULIC LIFTER OIL FILTER SCREEN
The access screw for this screen is located on the right side
of the crankcase beside the rear tappet block. Carefully
remove the screw to expose the spring and filter screen
located underneath. Remove the spring and filter screen
from the crankcase. Clean or replace the screen. Reinstall
the screen (open end down), spring, and screw.
GAS TANK FUEL STRAINER AND IN-LINE FILTER
Inspect and clean the gas tank fuel strainer according to the
motorcycle owner’s manual. If an in-line filter is used
(recommended) , it should be replaced or cleaned according
to manufacturer’s specifications.
CARBURETOR
The carburetor has been specifically set up for emissions
control. All jets are fixed at the factory.
Idle Speed Adjustment
1. Operate motorcycle until engine is warmed up
(typically 15 minutes).
2. The idle speed adjustment screw is located on top
of the carburetor just under the throttle cable guide.
Use a long, blade-type screwdriver to adjust the idle
speed to 900 RPM.
AIR CLEANER ELEMENT
The special carbon air cleaner element supplied with TÜV Long
Blocks was designed for superior flow and efficiency. The
element reduces intake noise emissions, as well as prevents
fuel vapors from entering the atmosphere while the engine is
shut off. The element should be replaced every 5,000 miles
(8,000 kilometers). It is designed to be run dry; i.e., without oil.
Note - oiling filter will cause improper engine operation. If the
poly-carbon element is torn, punctured or has excessive oil
build-up, replace the element.
Caution- A damaged, torn, or crushed element may release
carbon into the engine resulting in severe engine damage.
In the event of a damaged air cleaner element - replace
element immediately.
