New to 50's! Need insight!

Just picked up an 04 crf 50! Wooottt! Took me a day to learn fag drag sitdowns, ill eventually pick up my foot

But anyway its got an aftermarket pipe and open element foam filter, and it bogs in the low rpms, and some times cuts out in the top end. Im thinking it might need larger jets, but I wanted to see what most of you have done to your carbs with those mods? If it already is jetted is there a way to adjust the Needle clip or turn the air/fuel screw around?!

On most carbs u should have about 5 settings for the needle. The lower the clip (the higher the needle), the more fuel u gonna get. I dunno what u mean about turning the air/fuel screw around... 4 strokes have fuel screws (anti clockwise = more fuel) and 2 strokes have air screw (anti clockwise = more air). You cant turn them around. Have u taken the carb apart yet to see if the jets are dirty?
