3. When the engine is cool or cold and the ambient temperature is between40°F-60°F/5°C-
15°C, engage both enricheners to start. As soon as the engine starts, immediately retract
the enricheners. Run the engine at moderate speed for 30-60 seconds. If it starts to die,
blip the twist grip throttle (rapidly twist part way towards full throttle and then back off) to keep
the engine running. After 1 to 3 minutes, depending on ambient temperature, the engine
should run smoothly without “blipping” the throttle.
4. If the engine is cold and ambient temperature is below 40°F, first, give the engine 5-10
(depending on how cold it is) priming kicks with the ignition off. This will get some oil
circulated to key internal parts. Engage the enricheners on both carburetors. The engine
should
then fire, depending on how cold it is. For example, when the ambient temperature is 0°F, it
typically takes about 5-10 rotations to start the engine. As soon as the engine starts, retract
both enricheners (after a few seconds).
Note: It is very important to back off on the enricheners as soon as the engine will sustain
itself without stalling. Since the Ural is a carbureted air cooled engine, the plugs will foul quickly
(as soon as one minute) if the engine mixture is too rich. If one plug fouls and the other doesn’t,
the engine will run unevenly and may cause internal damage.
When the engine is hot, do not choke or enrichen the carburetors. To do so risks flooding the
engine.
To start an engine that is flooded, first open the throttle fully, hold it there and give the engine up
to 10 swift kicks. If it still doesn’t fire, take the spark plugs out to see if they are wet with
gasoline. If they are wet, dry them. Clear excess gasoline from the cylinders by kicking the
engine over 10 times with the plugs out and the throttle closed. Then replace the plugs and
repeat the starting procedure described at the beginning of this section (1).
WARNING: S
USTAINED OPERATION ON ONLY ONE CYLINDER FOR EVEN JUST A FEW MINUTES COULD
OVERHEAT THE CYLINDER AND CAUSE IRREVERSIBLE DAMAGE TO EITHER THE VALVES OR PISTON
. T
HUS IT IS
CRITICAL TO IMMEDIATELY SHUT THE ENGINE DOWN IF IT APPEARS TO BE RUNNING ON ONLY ONE CYLINDER
.
Additional Warnings: Once the engine starts, do not allow it to run at a high speed as this could
cause abnormal wear of the parts and may lead to seizure of the piston pin and pistons in the
cylinders since cold oil flows through the oil ducts with difficulty and fails to ensure sufficient
lubrication. A correctly adjusted warm engine should run steadily at low speed with the throttle
control
twist grip fully closed.
Do not let the motorcycle sit at idle for more than three minutes, as overheating could result.
