Is it close?

I have an 05 EX with an FMF Powercore 4, Powerbomb, K&N and an open airbox. I was wondering about Kehin jets and if I would be close with a 162 Main 40 Pilot and 2 1/4 turns out? I had a Dynojet 150 main 40 Pilot and 2 1/4 turns and it always ran rich so I'm gonna go with Kehins instead. Thanks.

162 would prob be rich. it will prob be between a 155 and 160. You will just have to play around with it and see.
