Honda NSR 125 / CDI units - how it should be finally?

[kozikowski11]

I have been spending some time on the forum for a long time. And thanks a lot @alains - I hope you still active on the forum;) And thanks for NSRtips.doc - very useful

Generally, I spend 2 years renovating the NSR125, mainly because it was my childhood dream. I am already on the final way and I am looking for the cause of the problem - why from 5000RPM (equal), the engine starts to work much worse, breaks/weakens (when I open a little more throttle - it stops breaks, but I feel that it is still weak). Not depending on the carburetor settings or air filter modification (I used 181ccm Malossi kit). After many attempts to find the problem, I found a CDI CI639 on my motorcycle. French imports, everything is right (B character in VIN). So this is a restricted version, I assume this is the cause (changes in the ignition timing, right?). I bought MIRACLES from the world CI572 (I know there will be no security stand) and CI626A (locked version Swiss / Germany) (CI626 is not available in the whole world). CDI other than CI639 are very hard to get / impossible. So now I have, CI639 (mainly from my motorcycle), CI572 and CI626A

And now:

Here we can understand that CI572 fits to CI639 / wire installation without any modification

Here we can understand that CI572 cannot be fitted to JC22 wire installation

Mismatch information!

So how it should be?
I currently have CI639 (mainly for my motorcycle)
- if I want to use CI626A, I have to change the yellow/black cable with the green one (reverse them). Can I skip BlackBox cables (2 orange wires) during this modification? Will it run and be in full power "mode" (unrestricted). Like a normal CI626? (CI626A-> CI639)
- if I want to use CI572, should I change the cables or not? I'm not sure because of the mismatch information @alains (CI572-> CI639) (full power, without security stand support)

These modules are already very difficult to get, anywhere from the world. I do not want to damage them by a wrong installation. It's a very expensive unit now.
Please explain how to connect CI572 to CI639, change the cables, or not to change?

P.S. And what does it look like with CI589, CI589B modules?
P.S.2 Honda XL has a CDI module labeled CI626 But a different part number, so I don't think that will work.
P.S.3 I am looking for a functional good CI626 module Maybe somewhere I can buy this unit?
P.S.4 Yes, I have RC unit TV-78

Please, @alain and other users - give me some advice
And thanks a lot for help
