What Jetting for 2002 YZ 250??????

[ShawnYZ250]

Just bought a used 2002 YZ 250. I have been fouling plugs using Yamalube mix oil mixed at 32:1, 94 octane.

The bike is stock. I'm not sure what jets are in there now since a racer had it before but I would like to know what's the best jetting is for stock? I ride trails and once in a while will go to an MX track but will never race. I don't ride the bike that hard so what's the best jetting for it? And what should I mix my gas at?

Thanks,
Shawn

What altitude are you at?
I'm at ~4200 ft.

In mine...with the stock pipe and v-force reeds and 70+ weather this is great.
