How does the bike run now? What are you looking to change.
First impressions looking at what you're running is.. Way small on the pilot.. Way rich on the needle.. I can't judge the main, but looks small for a 250 too.
I see you are at altitude which would mean you'd typically want to lean things out across the board, however the needle and clip you are running are really rich. Much richer than the stock needle (which many people at slight elevation find too rich).
At a guess I'd say your bike probably runs like a real pig from 1/8th - 1/4 throttle before things start to clear out into the top end. Really pulling well from 1/2 to WOT. I think the small pilot is a band aid to try and help clean up the rich taper and clip pos of the needle.
