RMK Electronic Ignition Kit Fitting Guides


This kit is a great solution to replace the ageing and now problematic OEM charging and ignition systems now over 40 years old.

Our Roadster kits are specifically designed to plug in to standard Yamaha wiring looms with only basic wiring needed. Our new billet stator is accurately machined and assembled to ensure perfect ignition timing. The modern 12 volt electrics are native to the Yamaha electrical system meaning minimal fuss. We do point out older machines or those from other markets may have had connectors changed or differences but these rare issues are simple to overcome.

The kit contains a new fully assembled 12V billet stator, electronic ignition unit, HT coil, voltage regulator & fitting guide.
