Can anyone give me the carb jetting, slide number and needle clip position to set up my rebuilt Fantic 305, as it runs weak at the bottom, when hot pinking and knocking when blipping throttle open quickly. Airscrew is only quarter of a turn out as well.

Thanks if anyone cas assist.

Ian

Don`t know any body with a Keihin on a Fantic. But do know that the Fantics always required larger jets! I`d guess a 125- 130 main and 48-52 pilot.

Contact Chris at Classic trials , he may be able to tell you a starting point .... But don't cook your bike in the meantime !!!
