Does anyone have the jetting specs for a 30mm Mikuni on a Six-Days Sachs engine?
Thanks,Glenn

Glenn, I'm useing the Sudco specs for the 74 cr125 Honda. With a bigger main and the needle clip in the #2 notch instead of the # 4 notch and a leaner pilot jet. 159 series VM-30-83 30mm Mikuni. Pilot jet, (35). Air jet, (2.0). Slide cutaway, (2.5). Needle jet, (P5) 159 series. Jet needle, (6f5) #2 notch from the top. Main jet, (270) RD 8mm hex type. I bought the carb from Pro-Flo and the only thing I changed was the overly rich pilot jet and I dropped the needle and went up from the 250 main jet to the 270. Good luck. G man.

Gavin,
Thanks for your jetting. I am running a 32mm so it is slightly changed but I think I want to tinker in the direction you are running. Never satisfied till they melt you know.:)
