IGNITION SYSTEM
The ignition system incorporates the power supplies, ignition coil, Hall Effect pickup, electronic mod-
ule, two spark plugs, a set of low and high voltage wires and the ignition switch.
The ignition system will provide the spark to the spark plugs from 200 to 6000 RPM. With the engine
at rest, the ignition system will draw 100 mA. With the engine running, the ignition system will draw
1.5 Amps. The operating voltage for the ignition system ranges between 7 to 16 Volts.
The electronic ignition system will automatically provide the required changes in timing to an accuracy
of 1°.
Ignition coil The ignition coil has two high voltage terminals, each supplying one of the cylinder
spark plugs and operating in conjunction with the Hall Effect pickup.
Periodically, check all wires in the ignition system to be sure they aren’t crimped or have loose con-
nections. Loose connections will cause erratic performance and poor fuel economy.
Spark plugs. In certain situations, spark plugs can quickly foul with carbon or soot. The plugs can be
cleaned but it is easier to put in a new set of plugs when on the road. We recommend that you purchase
an extra set of these plugs from your Authorized Ural Dealer and carry them in the motorcycle at all
times.
WARNING: D
O NOT OVERTIGHTEN THE SPARK PLUG WHEN MOUNTING IT ON THE ENGINE

DAMAGE THE CYLINDER HEAD

Functioning of ignition system. Both plugs fire simultaneously on the left and right-hand
cylinders, one spark being formed when the compression stroke terminates in one of the cylinders and
the other during the exhaust stroke.
