hi
i need some help tuning the fcr carb for my kx250f . The service manual doesnt indicate how much turns you need to screw the air/fuel screw and the bikes is working fine and perfect on open chock with 1 3/4 screw out with chock in it popps and wont idle so i`m guessing maybe its lean ? need some help with this carb they`r a big painnn to tune up :S . i even changed shims and are now up to spec checked all wiring new oil clean fuel cleaned carb with carb cleaner and air soo im thinking its a setting problem .
