IGNITION SYSTEM
The ignition system incorporates the power supplies, ignition coil, Hall Effect pickup, electronic
module, 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 accu-
racy 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
connections. 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.
