      The recommended jetting is 90 and 92.5 for the 125cc , same goes even for the leovince twin custom pipes made in italy too.  Pilot Jets = They stay the same forever.

      Go in tutorial section and look for these tutorials

      • Slide Mod (good mod)
      • How to remove the intake pipes (very delicate rare parts now!)
      • How to remove the airbox off the bike a proper way
      • Carb Jetting

      Where is the best place to get upgraded jets from?

      EBC UK makes em  or KeyStar Japan , I may have some in stock (as i keep a few for GT customers upgrading to K&N filters) , send an email.     Or any ask any local hyosung dealer such as TNorthEast  (one word) online as they are one of the oldest dealers still doing hyo parts, ring them for jets.
