RMK Electronic Ignition Kit Fitting Guides


Fully featured yet affordable up-grade that replaces the standard DT360A, DT, IT, MX & YZ 400 generator. Our new billet stator with precision location ensures perfect ignition timing, so there is no need to carry out any timing set up. Fit and go! Our modern 12 volt electrics are native to the Yamaha electrical system, designed to plug in with minimal fuss. A stock Yamaha wiring loom is needed and occasionally it is found some terminals should be replaced due to wear, damage or previous replacement, full details & parts required supplied.

This kit is great solution to replace the ageing and problematic OEM generators.  You can fit this kit with confidence that there are no tricky adjustments or wiring to do. Rex has developed this system over many years, refining it to a standard few can match. It is has been made to ensure fitting is straight forward with minimal tooling needed (a flywheel extractor is required).

The generator is the heart of your bike’s electrical system and we believe the RMK-8 (12 volt) system is an unbeatable choice in terms of performance, compatibility and reliability. We develop and manufacture our own ignitions here in the UK so we can bring you performance that betters the original Yamaha equipment at an affordable price.

We’ve taken the time to check our parts fit and work correctly with the bike’s electrical system. Our technicians have worked to ensure the least number of tools are needed*. The 12 volt stator plugs directly in to standard wiring looms, you won’t even need a timing light!

Requires the flywheel to be stamped “FOTO2171, FOTO2172 or FOTO2173”.

Owners who wish to experiment with ignition timing should see kit our RMK-9, this gives vastly increased spark energy and adjustable base timing point.

The kit contains; a new 12 volt stator and ignition source coil, 12 volt lighting coil, electronic ignition unit, new HT coil, voltage regulator & fitting manual.

Not included: Battery, bulbs, 12V horn and indicator relay.

Yamaha made many changes and didn’t bother to report them so occasionally we find that a market variation requires a slight change to connectors. These are simple to carry out and rarely happen. These are very basic to over come, generally only a wire needs to be moved to a new position in a plug.

*Basic workshop tools needed, flywheel extractor required (not supplied). See P/n FWP-1.
