? about my kx125

i just pu ta new pilot jet in it and it still has no low to mid range. it sputters untill it gets going fast any thoughts about what else it could be

It could be your air/fuel or maybe your main jet. Pilot jet really does not have all that much to do with anything except idle really. Did it sputter and stuff before you replaced it?

The carb might need a good cleaning or I would check your spark plug condition and gap, it could be anything from a dirty carb to your cdi, just have to check each thing ONE at a time, never do two things together because then you may screw it up worse or you will not know what fixed it

yeah it sputtered before so i replaced the pilot jet and cleaned the carb and it still does it

Lucas did you ever get this figured out or you still spitting and sputtering?

H Man.......you got any ideas perhaps "Mr. Carb Man"....

That sounds to me like the needle needs to be adjusted. The needle controls your mid-range throttle. If the needel isnt adjustable you can get a small shim to put under the clip.

do i need to adjust it down or up?

What position is it in rite now?

Have you added any aftermarket parts? If you have you will neede to raise the needle (lower the clip). That will dump more fuel sooner into the carb when you hit the throttle. My guess is that is what you should try anyways.

Yeah the needle might fix it, the problem with carbs is one thing will fix it and two things will screw it up so make sure you only do one thing and try that for a while and then try something else if that doesnt work.
