I am new to this chat game so please bear with me. I am an old Brit Iron man, but have recently been seduced by a young japanese model ( NSR 125R ). There is a problem, she is getting older and more tempremental.

She is a UK 1999 NSR125R and it looks like the CDI ( CI626 ) unit has stopped working. I have tested the unit and I get no readings across the green & red/white pins, which according to the manual should be between 2-150Kohms. I have looked on ebay etc but the CI626 seems to be very rare. I love riding her and I am not too bothered about speed and was wondering if I could just fit the restricted CI639 unit.

Yeah, it's a straight swap, but you might loose a bit of power. I swapped from a CI639 to a CI626 but I did have to bodge a new plug onto it.

I noticed you are in Lancashire. I you're anywhere near Chorley, Berties had a couple in (CI626) when I was last there.

CI639 & CI626 are not swappable like that . you need to cross green and black/yellow wire at the CDI 4 wires connector

look at breakers on ebay
but also you may fit an earlier model (CI572) straight away , the only problem is that you have no security stand

Thanks very much!

Do you have any info on how to set the throttle needle second from the top??

on top of the carb , where the throttle cable arrive , you see 2 screws . undo them then pull out the throttle (it comes with the cable) . in the center of the throttle you see the needle . the throttle has a hole where the cable go through and at the end it's a lead ball . the throttle has a slit , pull a bit on the ball and make the cable escape through the slit . warning about the throttle spring going nowhere . on the needle you will see a clip , set it on the second notch from the top Very Happy
