What are the stock sprockets for teeth? because who knows maybe you won't need as much torque as you might have.

stock in front is 13 and in the back is 38

well 14 tooth means more torque less boost and tighter gear ratios. the 39 would mean a small increase of boost and wider gear ratios. But that would be more torque overall then before you changed the sprockets which you wouldn't need with all the modifications you have I wouldn't think and a over sized header in diameter also means more torque. So maybe you should run taller gears. btw how tall were you tires stock and how tall are they now if you have after market tires? That could even mean more torque which you probably don't need unless you are a fairly large person.

nausty, dont confuse people.

14 is for more speed.
going form a 38 to 39 would tighten the ratio

I run 14.39 I am geared for mx

my friend runs 14/37 he is geared for more top speed (but my bike still stays with him :) )

remember, a larger front is more speed

a smaller rear is more speed.
and vice versa

here is a ratio chart.............

Alright this is how it goes

Front sprocket: more teeth more top end, less teeth more torque.

Rear sprocket: More teeth more torque, less teeth more top end.
