call white brothers and tell what you got and they should be able to help you with the correct jet size.
What he said.....! Your pipe Co. will have the jet info for you. I have a Pro-Circuit, K&N filter, open airbox on mine. I emailed P-C and between them and the instructions in my K&N jet kit, I did it myself and mine seems to be dialed in good. I asked the mechanic at Yamaha when I had the valves adjusted if the jetting was correct and he said it it was good. The jetting will really help get the fuel your beast needs.
