Ignition & Electrics

Ignition & Electrics

Dyna offers the best choice in replacements for the factory ignition. When my factory ignition failed I asked my friends on the list to help me with selecting a replacement. I had looked over the catalogs for potential candidates. I was told that it had to be Dyna, one of them even said that you are really not a true member of this group unless you have fitted Dyna coils to your FJ. So, I followed their lead, my bike is now running with a Dyna 2000 CDI box and a pair of Dyna coils. I am very pleased with their product. The configuration options are excellent and there are even presets just in case I wish to add nitrous to the setup.

Magneto Ignition

This definition is from a book by Joe Haile. Thanks to Jon Jarosz for providing it. Please note that this part is for off road use only.
Magnetos: Magneto ignition systems only look like distributors. Magnetos are self-energizing, and allow an engine to operate without a battery. They are usually seen only on drag racing bikes. Here are the advantages:
1) The faster they turn, the more energy they put out.
2.) Ultra high-energy spark.
3.) Adjustability. As with a distributor, this makes it easier to manipulate the timing. Magnetos are usually belt-driven and require the same space as a distributor.
A magneto ignition made by Mallory is available to work with the FJ. Contact Big CC Racing for details.

Ignition Wires

My FJ is fitted with a set of Taylor leads. They come with high recommendation and can be ordered though your local motorcycle shop.

Ignition Advancers

This is a very popular addition to the stock setup of the FJ. The results are said to be excellent with a noticeable increase in power output in the low to mid-range. The installation only takes a moment or two, however, a pneumatic impact wrench is required to remove the nut at the end of the crank shaft.

Spark Plugs

Again we are fickle. NGK makes the best spark plugs on the market for Japanese applications (that includes your Toyota car). Stock Plug Part # DPR8EA-9

V Series Plug Part # DPR8EV-9

Alternator/ Voltage Regulator

Another annoying issue with the early FJ's is that the stock voltage regulator puts out too much power. The result is shortened battery life accompanied by a tendency for the battery to boil dry. There are a couple of worthy solutions.
The first solution is to replace the regulator and rectifier. The alternator must be removed and partially disassembled in order to accomplish this, as the FJ's alternator is designed more like an automotive alternator than a motorcycle alternator. The models that provided a solution for one of my friends follow:

K&L Supply

20-8532 Voltage Rectifier 102.99

20-8534 Voltage Regulator 74.99

It has been noted that these parts can be ordered though most motorcycle dealers.
There have been others that have designed their own replacements for the factory parts. I should leave the details to them. If you are interested join the list and ask.
The second solution is to put a larger, more resilient, battery in place. This is done by removing the battery box and replacing it with one from the 89 and up. The problem was solved by Yamaha by putting a sealed battery in place. The sealed battery would not boil dry for obvious reasons. This is a simple solution that requires only a little rearranging of parts underneath the plastics.

Tail Light Failure

The FJ has an annoying tendency to eat tail light bulbs. A simple solution to this issue was offered that I have to pass on. It was suggested that as the plastics wear and the rubber parts get older that the tail light assembly get loose and starts to ruin bulbs as a result of vibration. The cure is simply, to put a rubber o-ring in place between the socket and the light fixture. Simple, cheap and seemingly affective. What more could you want?
