Whether you have a street, touring or race bike,
the powerful sparks of the MSD MC-3
Ignition will improve your motorcycle's
overall driveability through
complete combustion of the
fuel mixture. If your engine
is equipped with sensitive
multiple carbs, the MC-3
will smooth things out in
the case of less than perfect
carb synchronization.
Not only does the MC-3
produce high-output sparks,
but it also fires the spark plug
multiple times to ensure combustion
and prevent plug fouling.
Unlike the stock ignition which
fires the plug only once on the
combustion stroke, the MC-3 uses
state-of-the-art digital technology
to deliver a series of hot multiple
sparks at low speed where poor fuel
atomization occurs. This envelope of
sparks (up to 10 at idle) quickens starting,
smooths out the idle and improves
off-line throttle response.
A high speed RISC microprocessor accurately keeps tabs
on the rpm, rev limits and timing of the ignition. The MC-3
accepts trigger signals from the stock ignition so you can
retain the factory ignition curve, or for racing applications,
Hall-effect pickups can also be used. The MC-3 Ignition can
be used on single, two or 4-cylinder motorcycles using single
or dual output coils with points or amplifier triggering.
Two-Step Soft-Touch Rev Control
The MC-3 features MSD's accurate rev limiter. By setting
an rpm limit you can protect the engine from over-rev damage
due to missed shifts or broken drivetrain. The rpm limit
is adjusted with plug-in modules and the MC-3 is supplied
with a 10,000, 11,000 and 12,000 RPM Module.
Not only can you set an over-rev rpm limit, there is also
a feature that allows you to select a second rev limit! This
is great to activate on the starting line to hold the rpm at a
steady level. This will help keep your holeshots consistent
and quick.
Air Shifter Ignition Interrupt
This feature produces smooth, backfire-free shifts with
automated air shifters. By wiring this circuit to the shifter,
the ignition output is momentarily disabled whenever the
shifter is activated. This safely unloads the transmission
for lightning quick shifts with no backfires!
Built-In LED
The MC-3 makes it convenient to time your engine
with a built-in LED on the side. When a triggering event
occurs, the LED lights up - perfect for static timing
your engine plus it is helpful in troubleshooting.
