i was just wondering what size jets you were all using in your 400ex's. i would like to know the main, pilot, and needle. also, indicate airbox mods and engine mods if you don't mind. thanks

how does the sparks main jets compare to the keihins? are they the same size or is one bigger? i know keihins are different than dynojet.

I am sure it is the same jets that you have just sold by sparks.
