Sorry to say I don't have an H loom handy - it's at the back n beyond of my store room or I could have laid it out and shown you.

For some reason the manual doesn't show the Pink wire but I guess it would then make it too easy to come up with a bypass for it.

I am sure there is a thread somewhere telling you what size of resistor to connect to what pin of the CDI to fool the speed circuit.

MM!

Just read through this topic, and its got me wondering, i am building a track bike and have had my loom converted to a race loom my track electronics i think it was, it is connected to a uk CDI, will it be in failsafe mode as i have no speedo?

Your all right Dolts , UK CDI has no speed restriction circuit in it.

Developments

There is a pink wire on the CDI. I get the resistor to ground mod, this will take place this week and will report back.

The number on the CDI is not one I have seen on the forum. Red label, 21119-1271, 131800-5240, 12v TNCF07 A is a Denso unit. Any info on this fella's?

Thanks

I did a little more digging and as you confirm its a Japan spec cdi with the speed limiter. I will fit resistor to overcome this.

Gotta say this forum is a fantastic resource for the ZXR.......

I did look at programmable CDI's for £165 but the resistor is deffo cheaper. :excited
