4. If the engine does not start after several kicks or ve seconds of
cranking, shut the ignition o for 15 seconds to let the starter cool.
5. Open the throttle slightly and press the starter button or kick the
engine through again. It may be necessary to re-prime the engine.
If the engine kicks back, the throttle may be opened too far.
6. Once the engine is running, use the fast idle lever to maintain the
proper engine speed required during warm-up.
7. When the engine has warmed up enough to idle without the
enrichment system, disengage the fast idle lever. The fast idle
lever is not required to restart a hot engine.
SUPER E & G CARBURETOR TUNING GUIDE
1. Verify carburetor is set to stock settings:
a. Idle mixture screw, 1¼ turns from lightly seated.
b. Idle speed screw, ½ turn clockwise from engagement point.
c. Accelerator adjustment screw, two turns counter-clockwise
from seated.
2. Start bike, bring to operating temperature.
3. Set idle speed adjusting screw, clockwise to increase RPM,
counter-clockwise to decrease RPM. Idle RPM range should be 950
to 1050 RPMs.
4. Adjust idle mixture by turning idle mixture screw slowly clockwise
until the engine runs poorly. Note position. Slowly turn the screw
counter-clockwise until it starts to stumble. Note position. Set
the idle mixture screw halfway between the positions, or at the
strongest idle. Inconsistent idle may indicate a manifold leak.
5. With engine idling, turn accelerator adjustment screw clockwise
until it lightly seats. Snap throttle open—engine should stumble.
Turn screw counter-clockwise ¼ or ½ of a turn at a time, until
engine responds to throttle twist with smooth, quick response.
6. Ride motorcycle in various RPM ranges, and then try to maintain
a consistent 40- to 50-MPH. If the engine has a at spot, or
is popping/sneezing in the air cleaner, it can indicate a lean
condition. If you notice stumbling or sputtering, it can indicate a
rich condition.
7. Low RPM operation is controlled by the intermediate jet (#11). If
sneezing or popping is experienced below approximately 3000
RPMs the intermediate jet must be replaced with a larger sized
(richer) jet. If the engine does not run smoothly at low speeds,
fouls plugs, blows black smoke or gets bad gas mileage a smaller
(leaner) intermediate jet needs to be installed. Always readjust
the idle mixture (#2) and idle speed (#1) screws after making a jet
change.
8. To test the main jet, do a roll-on from 50-MPH to 70-MPH in 3rd
gear. If the engine backres or breaks up in the carb, increase
the main jet size .004". If the engine is at or will not accelerate,
decrease the main jet by .004".
9. Since 2004 S&S shorty carbs have been tted with an adjustable
main jet air bleed (#13). Changing this jet to a larger size will delay
the signal to the main jet, therefore aiding with high speed tuning
as described in step 8. This also aides with tuning an engine that
is tted with an exhaust system that is not intended for high
performance. The air bleed uses main jets, the stock size is 40. If it
needs to be changed the range is normally 50 to 60.
