Blitz 250 perfomance upgrades, help?

[Atomik drew]

Just got myself one of these blitz 250's and after 5yrs on the kx250f and rmz250, I'm wanting more from this little bad boy. I heard about a few mods to do but need some clarification.

The carby jets.. What's best and wher can I get them? Or is ther a whole carby I can swap?
The airbox hole mod... What size do I cut?
The CDI upgrade.. Are the eBay ones any good?
Is it worth changing to a hi-power coil pack?
Cutting down the exhaust pipe for better back pressure??
Any other tips wld b greatly appreciated!!!
Cheers

Could you post some pics of your bike by any chance? Quite interested in getting a 250cc.
