1989Fzr6 3he bike/ 1995 4jh engine

Hiya i have a Fzr6 3he bike which has a 1995 4jh engine fitted but the cdi boxes are different including connections.

With all the 3he wiring and cdi box the engine turns over sparks but back fires throw the carbs which ive been told is timing so have bought a 4jh cdi box and wiring loom so would like to be able to wire the 4jh cdi in to the 3he loom.

I have a haynes manual which has wiring diagram for both bikes but it dont cover all the wires that come from the 4jh cdi box and there is more connectiing to it then the 3he cdi

Was wondering if you knew best way to go about doing this

Hey. I have juat bought a kawa zx9r. But the guy said he fitted an.other cdi so the rev counter dont work.. how do i fix it? Do i hve to replace the cdi to its original.one? Then the bike will be slower

Why do you think the bike would be slower? a cdi is mearly a box that regulates ignition pulses. There is no power to be generated here, unless you're flashing your ecu and re-mapping yout ignition table. Just run the original CDI. It's easier and cheaper to make yourself faster than your bike faster.

Will late 90s honda cr80 stator cdi box work on 1989

Probably not, without some other modifications 10 years is a long time in the world of off road bikes.. For one that will fit check for the part number rather than the model number of your machine, you may find that the same CDI was used on other bikes from the same maker, but of a different size and type (scooter or chopper or even a bigger engine in the same range, (125 or 175) good luck.

Hi. I have a stock 1998 kdx 200 that needed a blackbox. I bought a replacement cdi but the wiring on the bike is different to the 98 cdi unit. Colors are different too. The wiring on the bike is a kdx as...

Try following the wire from the stop button on the handle bar back to the CDI box. Simply unplug that wire. CDI is disabled by grounding. Does the KDX have a key switch or just the stop button. Try just connecting the pick up wire to the CDI and CDI to coil. You have to isolate ground to CDI to run. Check air gap at pick up. Use a matchbook for a gauge.(.018)

You must make sure that any other cdi unit is compatable with your make of bike .Best advice is to obtain the same as fitted on you bike ..check the unit model type rating and output .

Will a cdi ignitor unit off any other bike fit onto my yamaha fz750 1987 ? regards peter

Some will, but not all. The plug will differ from model to model, and the electronics may differ slightly as well.
