Oh yeah!! I have a DG pipe, Boyesen Reeds, UNI pod filter, and the PWM carb is very similar to the PWK airstryker. So if anybody has similar setup let me know what jets you r running. Thanks

I just installed a 38mm mukuni on my Z and im running a 390 main. Not sure on how far off the Keihin carb jetting is though.
