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!

sounds like the needle is to lean.

thanks
