CANT GET IT TO IDLE - 2005 Suzuki DR-Z 125

You've failed to plug an air leak through some little tube or hole.

try changing the scv suction control valve

YOU HAVE A VACUUM LEAK OR THE IDLE AIR CONTROL MOTOR ISNT FUNCTIONING OR NOT PLUGGED IN.POSSIBLE PLUG OR PIN DAMAGE IF PLUGGED IN.

bad oxygen will idle speed also clogged fuel filter,faulty fuel pressure regulator, dirty fuel injectors will cause engine to rough idle.

You have to remove the carb & remove the plug to
get access to the idle screw

Idle is computer controlled and not adjustable. If there is an idle problem, may be idle control motor (throttle body mounted) or bad throttle position switch.

Bigger jetting (a higher fuel/air ratio) will not cause overheating. But an air leak between the engine and carburetor can cause overheating - and an erratic idle. Make sure the carb is correctly connected and there are no air leaks. An air leak could also be the cause of the popping that you were attempting to address by re-jetting.
Once any air leaks are corrected, adjust the idle mixture screw to attain the highest idle speed when the engine is at normal operating temperature. Then, use the idle speed screw to set the correct idle speed.
Finally, ride the bike at full throttle for a short time, pull the clutch and coast to a stop. Remove the spark plug and check the color; a tan or light brown color indicates correct jetting. Too light = too lean. Too dark = too rich.

have you checked with ford directly or looked intheir online catalog there should be numbers on the part try them online in the catalog ok

no, there is no idle screw on them if it is fuel injected. although you could try changing the idle air speed sensor

the only thing that can change your idle speed that much is the the isv idle speed valve u have a faulty valve or your computer is faulty
