Does anyone know what the stock jetting is for a 2000 KDX 200?

I can't seem to find it in my service manual.


Eric Gorr suggested I start with stock jetting.


I have his 225 big bore kit, v-force 3 reed system, fmf gnarly pipe and fmf turbine core 2.

I think the stock jetting is a 160 main and a 48 pilot and that was pretty rich!

Any recommendations on where to start with my mentioned mods?

Can you translate the bold items? I'm not too adept with this terminology.
