yz426 supermoto jetting? Help!

Hi Guys

I bought a 02 yz426f supermoto 3 years ago and have had many hours of fun riding around the countryside ( :ride: on 1 wheel most of the time! :ride: ) and never looked back since.

I Recently purchased a white brothers E series exhaust and have drilled the airbox in the search of more power.

Does anyone know what jets i should be running?

The jetting is stock at present but needs changing as it is not running properly

Any help would be much appreciated

Thanks Andy
