what would the jetting specs be.05 crf 450

my elevation is 2400 to 2600' elev. high desert riding mostly dry climate. Is standard jetting at sea level ok? :cry:

I think it should be ok depending on what main jet is in it?

But You should need a 165 main .

Yes, 165-168 main, 1 1/2 turns out on the fuel screw.
