Bike ktm 250 exc rfs 2004 mods: t4 pro circuit pipe carb pilot jet 45, main 140 needle 2 from top problem runs ok I live at about 10000 feet around 12000 feet the bike sounds really deep. From a stop I will go about 10 feet and it will die. ( sounds like it is bogging dow, I rejetted to same needle clip postion pilot jet 40 main jet 132. Now when I give it gas from a stopped position it dies at any altitude I hace to slowly work the throttle to get it going. To me I think it is to lean now. Do you have any recomendations on what to change? either pilot or main or needle clip. as always your advice is greatly appreciated thanks!
