jscharphorn Posted May 7, 2013 Report Share Posted May 7, 2013 stock carbs with stock motor with pro circuit pipes k& N pods V-4 reeds billet intake and fuel / air screw was at 1/2 turn out, I turned it to one full turn and it will start still with one kick but at 1.5 turns it will not start well at all. Does the screws have anything to do with how the motor runs other then starting and idle ? and being at 1/2 - 1 turn out is this ok or does it look like I need bigger pilots ? I am not sure what is in it Quote Link to comment Share on other sites More sharing options...
oldskool Posted May 7, 2013 Report Share Posted May 7, 2013 Anything less than 1/2 turn out would suggest a larger pilot. Quote Link to comment Share on other sites More sharing options...
jscharphorn Posted May 7, 2013 Author Report Share Posted May 7, 2013 Thanks, so even at one turn out does that lean the bike out ? Quote Link to comment Share on other sites More sharing options...
J-Madd Posted May 8, 2013 Report Share Posted May 8, 2013 Leaner than 1/2 turn.....Pilots and air screws feed fuel throughout the entire throttle range but are overrun by the fuel supplied by the needle and main at more than about 1/4 throttle. If tha makes sense. Quote Link to comment Share on other sites More sharing options...
noonansar Posted May 18, 2013 Report Share Posted May 18, 2013 Rich-in, Lean-out. May want to start around 1 to 1.5 turns out and get it to idle by tweaking the air screw and idle screws back and forth until you find a good idle and good throttle response out of the hole. I had pc pipes and mine had good throttle response at 1 turn out, but everyones bike is different. Check your pilots and make sure they are absolutely clean. If they are patially clogged it will have a high lean idle. Quote Link to comment Share on other sites More sharing options...
