Rejetting on a 250x

[250xdude]

I am awaiting for a Wb/ e series full exaust to arrive and have never done a rejet, But I think I can do it myself, Anyway does anybody know what the settings would be on a 250x, the manual sezs it's factory set as follows:
Main:125
Pilot:35
Needle clip:3rd groove

I also plan to drill 3 1 inch air holes in top of box.

One more stupid question, do I need to buy a bigger main and pilot needle to replace the current ones? Thanks

on my 250X i have a 135 main and a 38 pilot. I also have a WB slip on and a Uni air filter.

P.S good choice in pipes im very pleased with mine

Thank you , very helpful, Tough decision between an Fmf or Wb/e
but everyone I talked to said wb was best. How's that uni air filter work for ya, I forgot to mention I have a K&N on the way too,
I called the local shop today and he said if I bring the carb to him he'll set the jets, I'll probably go that route because it's easier,
