I bought a set of carbs to put on my 1994 cbr 600 f2 and I pulled the bowls off and the jets out to clean them and discovered that the jets that were on the old carb said 122 and the jets on the new carbs said 135rd. Does anyone know if this is an aftermarket jet. Hopefully it is. Hit me up big time.

 

It's pretty likely that it is... bigger main jets anyway. You dont have a California model do ya?? Those might have smaller mains.
