      I’m rebuilding a CR125 for stock moto and I believe it has the Mikuni 36mm carb on it (it says Mikuni and ‘TM’ on the side).

      My question is, should I rebuild and run this carb or get something else?  Is this the only carb I can use in stock moto?  I ask because I have read that these are hard to tune (Don’t know if that’s true though).  I will buy a full jet kit for this carb if it will help with tuning.

      Ty ty for any help

      Your 36mm carb I would guess is a Keihin PJ?   You want the Keihin PWK or PWM, 38mm

      Are those legal for stock moto?  Which of them is more preferred?

      Also I picked up the Swedetech  actuator and kick start plugs; do I remove the rubber oil seals before install them so they will mount flush, or do I install them on top of the rubber oil seals?

      thank you

      Both PWK and PWM are legal in stock moto. The PWM has a little more top end.
