Change Needles and jets

OK, well I went into GP Honda in Mt. Maunganui and rummaged through their jetting containers.
I got 2x95 main jets and 2x90 main jets. ($7 each)
I also got 2x needles[needle number reqd].($5 each) These needles seemed exactly the same as the original XT CV carb needle, with just the numbering now different (and sensible).All Keihin stuff.

I put in the new needles and 90 jets.(down from 100)
Took it for a spin down the road and it all seemed very similar.

I think I really need to try advancing the ignition in the upper midrange to top end, to get it to have decent response up there.
