Problem with cdi/power valve Honda NSR 125

[loolladin]

Hello everyone,

I bought myself a Honda NSR 125 this weekend. The bike was born in 1997 . After a good old maintenance on the bike i started the engine and i noticed it was restricted.
So after alot of reseacrh i now know the problem is my cdi and my power valve control?
Cdi mounted is a CI 639 and the pv 124.
I managed to get my hands on a tv 74. I also ordered the wrong cdi (626A). Now i'm wondering if i cut the shunt on my 639 cdi, will it work with the pv74 power valve control? Because it seems impossible to get a CI626 .
I'm sorry for my bad English, but i'm not native English. (Old and dutch speaking)
All help is welcome.

Some bikes have the power valve restricted by a jumper which connects in the little wiring box to the left hand side of the cylinder of the engine.

My 2004 UK model had this. If you unplug it, the power valve works fine.
It's literally a little plastic jumper with a small loop of wire looping one pin of the connector back to the other. When plugged in, it disables the power valve for markets which required restricted engines for learner riders.

Hi, check out https://www.125ccsportsbikes.com/

There's a guy in the Honda forum called Alains (think he's form France, he has a wealth of knowledge and documents to download to help you de-restrict your old girl.

I had an NSR 125RK for my first road bike, loved it!
