Description
Our brand-new CDI unit has been developed for riders who still appreciate the raw punch of Yamaha’s legendary big-bore two-strokes.
The same electronic power house is found on some smaller models too.
Built in England and hand-assembled by technicians passionate about classic performance motorcycles, these units have been extensively refined and tested to deliver reliable, crisp ignition performance worthy of the original machine, without the ageing electronics headaches.

A new CDi unit is only one part of the ignition system, so if a brand new ‘plug-in’ CDi unit does not fix, or changes the symptoms then your next action is to consider other parts in the system that may need to be replaced or repaired to clear the problem, especially where that system is already much older than its intended design life.
Remember – just the same as when you rebuild a 2-stroke top end, you may hope to get away with a set of rings – in reality a rebore, new piston, small end and gaskets are required. The same is true with ageing electronics, a simple ‘plug -in’ box is only one part of tired and degraded system.
To support owners of ageing motorcycles, we have produced a free technical guide covering common CDI ignition faults found within older electrical systems. Many of the machines we specialise in are now over 30 years old and the electronic ignition has far exceeded it’s intended design life. A successful repair can often require far more than simply replacing one component in such old electronic systems.
