Maybe somebody can help with this,

03' 300EX, stock carburetor (Keihin), motor is stock.

Has K&N Filter with airbox lid ON, no holes drilled.

Does anyone have any jetting recomendations?

try a 125 main,start with lowering the clip one notch ,i would go out another half turn on the fuel screw and go from there:)

you may wana go higher than a stock main not lower( stock is a 128) as long as you keep the lid on id go woth a 130 maybe a 132 not much more than that, if you remove the lid you need to richen it up alot more like a 138ish.
