imexian Posted June 15, 2013 Report Share Posted June 15, 2013 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 Quote Link to comment Share on other sites More sharing options...
lineaway Posted June 16, 2013 Report Share Posted June 16, 2013 (edited) 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. Edited June 16, 2013 by lineaway Quote Link to comment Share on other sites More sharing options...
