Yamaha XJ, FZ and FJ Range

This page covers the XJ, FZ and FJ range of motorcycles that have ELECTRONIC IGNITIONS with electronic advance.  We cover models built from approximately 1982 to 1987 (when analogue electronic ignitions were phased out and replaced with digital ignitions).  
Note: some models went into the 90's with this type of ignition system, e.g. XJ900.

We have listed the year the model started and ended approximately with this ignition type but some countries could have earlier start and later stop dates.

If your model is not listed, we may still be able to help, as Yamaha seemed to run a common ignition unit on several different models.  We use the serial number of the ignition unit on Yamaha as opposed to the bike model number for identification.

The identification number will start with TIDxx-xx and have 4 numbers after it.  
As an example, TID14-21

Yamaha FJ 400 1982 to 1987
Yamaha FJ 750 1982 to 1987
Yamaha FJ 900 1982 to 1987

Yamaha FZ 400 1982 to 1987
Yamaha FZ 750 1982 to 1987
Yamaha FZ 700 1982 to 1987

Note:

Including 1983 FJ1100 with the vacuum advance system incorporated into the ignition unit, i.e. it has a vacuum hose going into back of unit.


 

Yamaha XT & TT Range

This page covers the XT and TT range of motorcycles that have CDI (Capacitor Discharge Ignition) ignition.  We cover models built from approximately 1982 to 1996 within the XR and TT range.  XT units come in 3 different wire configurations per model, depending on the country that it was originally sold in.

i.e.  8 wire 10 wire  11 wire

We also have units for the XT 250 that was produced between 1980 and 1984.

Important note:  Some of the later model Yamaha bikes were supplied with TCI (Transistorised Controlled Ignition) as shown in the left image below.  These units are identified by the connectors built into the unit, as opposed to the CDI unit that has individual leads going to the connectors (as shown in the right image).  Please be aware that a CDI unit CAN NOT be used in place of a TCI unit.

It is important to identify the type of plug configuration that the bike's ignition pack has.

There are two types used.

The first type has plastic plugs as seen below in figure 1, and the second type has bullet connectors as shown in figure 2.  When ordering, please state which connector type you need.
