Throttle response

[300EXrider02]

I tried this question before, no one helped

My throttle response is kinda dim, not gettin the good "puch" i need, and it might be running a bit fat, right when you pin it in 2nd or something it will hesitated, stutter once then get going

In other words, I could do wheelies in 3rd gear with pinning the throttle, now i can only do them in 2nd, and it still is hard as heck, and bogs out and has no response

I know or almost positive its the main jet running a bit fat, just wanna make-sure, i might as well check the plug, but just wanting to see what you guys thought

havent had the best time searching for a past problem that had nothing to do with what i was thinking, thanks

same here mine is alright with the weelies. but when i sptab the gas it hesitates then it goes. when im movine it moves good only when i stab the gas if i go slow it pulls out with no problem. im running all stock jetting. the spark plug is brown the spark part and the arm that goes over the flint or whatever it is and the threads on the plug are black.

ill try to get a picture soon.

Try adjusting the air/fuel mixture screw it will help with the throttle response.

I got it at 3 turns out, should i do 2.5? or 3.5? does it need gas or too much?

[KASCHAK]

my 250 was doing the same thing, hesitating in lower rpms and stuttering. i just moved my needle up one slot and more on the air screw and it got it punch back.
