CRF cuts out on bottom end.

[Narly R]

When my bike starts to bog, and then i pin it it wants to die, it wont pull out of a bog sorta thing. Any ideas? Is it my needle, or maybe my pilot jet? My needle is in the middle right now, if it is cuuting out, should I move it up or down, is it getting too much feul? Thanks:)

Well I moved the needle down, and it made it worse, so it is as high as possible now, it is on the bottom notch. It still cuts out. I might try messing with the air/fuel mixture screw. It runs fine on the top end though, so I dunno if it is the main jet. I might try a bigger pilot.

its possiably because of cloged jets, or there adjusted wrong, its diffenity a carb/jet issue in my opinion
