Need Help Jetting My Z!!!!!!!!!

[Semo Tri Z]

I just added a 38mm PWM Keihin carb to my 85Z. Anybody have any tips on where to start with the jetting. It has all stocks jets now. 172 main jet. I believe i need to go smaller, but not sure. Help if ya can please.

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.
