PWK 38 jetting on an 87

[GreyJones7]

Hey Guys,

I have an 87 that needs some jetting help. This is my first time on a 500 and I think it's too rich up top. Here's my setup, let me know what you think please!

1987 Cr500, boyesen rad valve, FMF gnarly + PC silencer, Keihin PWK 38 Carb.

Elevation: 300 Ft.
175 main
60 pilot
40:1 Power Plus Lubricant
Needle and clip are still on stock PWK 38 settings (not sure what those are??)

I'd be very appreciative if anyone can give me a hand.

Thanks
Greyson
