hi i have a KSR GSR 125 which has a carb called EXACT . The main jet says 260 on it and i need to upjet to 295 or so. I cannot find anywhere that supplies jets for the EXACT carb nor any jets of this size. Does anyone know where i can get them from or advise if the stamp on the jet saying 260 is actually not what it says?
You need a thread gauge and a vernier. Thread gauge to tell you the pitch of the threads, vernier to tell you the outside threaded size. For example M6 x 1.0, or M5 x 0.7 (outside diameter x pitch) Then can just match with others like dellorto/mikuni
