...they also offer a "stage 1" style kit/mod for the MZ although it's not listed in the manufacturer's menu (that I could find) - email Marc if you have any questions - he's good about answering email and he's very knowledgeable/sharp (IMO).
Hey cat-tard did you put the stage 1 jet kit in your bike? If so did it make a difference compared to turning the idle mixture screw out 5-7 turns? Would you consider changing to a different carb?
