2nd) Twinair gage and airfilter
3rd) Change exhaust
4th) head porting
5th) Adjustable ignition (vortex)
6th) Big bore (Athena etc.)
I just put these in the order I would do them. Jetting and exhaust will make biggest and cheapest difference. To do the jetting right you need to dyno your bike.
I have done from 1 to 4 so far and dynoed my bike after every mod. Vortex ignition is coming so that is next.

Second is muffler change and jetting. Power wise, this is all you really need to do. There is much more you can do, but not really needed.
I have a vortex ignition on my bike, they are great for dialing in your power to suit the terrain.
