1972-77 Honda CB350F / CB400F Dynatek Dyna S Ignition Ultimate Kit
$699.95 USD
Description

Go all-in on Dynatek with this Dyna S Ignition System Ultimate Kit, bundling the Dyna S ignition module with Dynatek brand 5 Ohm dual-output coils and Dynatek performance spark plug wires. A complete turn-key ignition upgrade for your CB350F or CB400F Supersport.

The Dyna S is a self-contained electronic ignition built with state-of-the-art engineering, the same ignition used by top racers for over two decades. It's completely housed behind the ignition cover and uses a magnetic rotor with the original spark advancer, preserving the factory advance curve. Increases power, reduces vibration, backfiring, and intake reversion, especially on engines with radical cam timing. Front and rear cylinder timing can be set individually. Perfect for hot dual-plugged engines. Very high quality, made in the USA.

Includes instructions and a one-year Dynatek warranty.

Frequently Asked Questions

What is included in the Dynatek Dyna S Ultimate ignition kit for the Honda CB350F and CB400F?

The kit includes one Dyna S electronic ignition with its magnetic rotor, two Dynatek 5-ohm dual-output coils, Dynatek performance spark-plug wires and installation instructions. The two coils provide the two paired-cylinder ignition circuits required by the four-cylinder engine.

Does the Dyna S kit eliminate the original mechanical spark advancer?

No. The Dyna S magnetic rotor works with the motorcycle's original spark advancer, retaining the factory advance curve. Inspect and service the advancer as needed because the electronic module replaces the contact points, not the mechanical advance mechanism.

Which cylinders share each ignition circuit on a CB350F or CB400F Dyna S installation?

One Dyna S module and dual-output coil fire cylinders 1 and 4, while the other module and coil fire cylinders 2 and 3. The timing of the two cylinder pairs can be adjusted independently.
