A couple questions

Throttle stop cut
Air box lid
Custon vortip, opened to 1"
Grey wire cut
I tried YZ timing before the grey wire got cut and wans't happy with the low end, so I changed it back. I did nothin else. I am thinking of trying it again now that the wire is cut. I noticed some change with the wire cut and was thinking that the YZ timing may be better now that the wire is cut. Just looking for thoughts on this. I was also wondering if I should have adjusted the needle clip location when I did the YZ timing.
maybe I should just leave it alone.

Have you experimented with the jetting?
Also, if you use the stock head pipe, check the weld between the flange & the pipe. Mine was built up 1/8"+ all the way around. A die grinder got rid of that.
I'm also running the vortip, though a little less modified than yours. It's just strange that it takes away bottom/mid but pulls strong on top while restricting flow.
I'm hoping I can jet the bottom back in. I'm just really slow.
I'm currently at: DVP#4, 175 main, 45 pilot (too lean, soon to be 48), vortip with tube ends thinned & flared, YZ cam timed, airbox lid gone, octopus retained, gray wire pulled. @ 1000-3000 ft.
This summer I've committed myself to riding w/vortip. The power was perfect without, but just too darn loud.

I think you should fix it by purchasing a 520 ;-)
Seriously, why would you change anything on that bike? The power always seemed perfect to me.....
