#250 main,R-0 or R-2 needle jet 6EPO5 second clip, #35 pilot jet. ;)
You will probably need to pull it apart and check what you have in it as I think only the slide and pilot jet are correct ::)

It also depends on what expansion chamber you have on the bike. A mate of mine has run different types, and has had to re-jet the carby to suit each one.

I heard of a mikuni carb brand new from the states which would not work well under load.
It had too small of a Seat and needle sized to suit a snowmobile which has a fuel pump and when hooked up to a bike fuel fed by gravity it was starving of fuel under load down the straight an nepean

Neddle should have a long thin taper from factory ...."D project" is onto it, pull all you old jets and neddle sout of the old and transfer the into the new carb and it should be close.
Did You check the intake sizes ( ID ) to see if there is any diffrence 32 >34

Hey,don't forget it's a 125 ::).
All the tests I have read on that model describe it as a top end motor.
Mine works ok with those I have listed ;)
-
Yes as D project said this model is a top end machine.I used to race one and it wasn't the greatest powerband and pretty non existent down low.
