grindrod Posted February 28, 2018 Report Share Posted February 28, 2018 I have a 2012 125 Randonne bored out to 150cc that could benefit from slightly richer pilot setting but I don't know which way to turn the adjustment, it is high up on the carb body and GG call it an air screw so my thinking is that it is adjust inwards to richen. Since it is difficult to get at can anyone confirm which direction for richen, I understand it is a PTK carb. Quote Link to comment Share on other sites More sharing options...
