There is a section of Eric Gorr's
Offroad and Motocross handbook on '90-91 KX 125's pg187-88
I would highly recommend getting the book, there is stuff for new guys and engine builders alike. (or search the book in amazon :wink: )

Thanks buddy!
I think im gonna email them and ask about the needle. I tried today to measure my needle and didnt get any usable information.

Jopiz:
Guys at Sudco couldnt help me with the needle. They said that N0EJ is the Keihin mark but it is a multi taper needle only available to the OEMs, so they didnt have an equivalent.
I wonder is there a "how to measure your needle" tutorial or something? A book with that kind of information would be worth to buy. :roll:

Friar-Tuck:
At the top of the needle page there is a diagram on what the measurements are.
You should be able to use this to find an equivelant or "close".

Here's another site that says they may to be able to get discontinued OEM carb parts.

Jopiz:
Well, the problem is, i dont know how to measure that thing. To me, it just doesnt seem to have that "L1" straight section at all. I can measure or calculate the taper. And where to get that diameter measured? 8-)
Is that L1 lenght from first clip to the point where needle diameter is 2,515 mm?
