Alignment not holding after track days
My '07 has had a slight pull to the right ever since I bought it. Let the wheel go and it drifts to the right, wheel held a little to left past center keeps is straight. I've had it aligned at 3 different shops. All of them manage to get it tracking straight, but as soon as it hits the race track, it goes back to pulling to the right. This last time I didn't put a wheel wrong, no offs or dropped wheels (wasn't driving hard enough 
). Suspension is stock minus the Ohlins. I've had the alignment techs max out the stock camber adjusters and adjust the toe to stock specs. When I say max camber, they are making sure it is even left to right. i.e -2.5 on both front wheels. Subframes seems to be staying put with no loose bolts. Any ideas?

The camber (and caster?) lock nuts are supposed to be replaced at every alignment according to the Honda service manual.
If you don't replace them then you need to go waaaaay over the Honda torque spec. Iirc the Honda spec is something like 40 ft lbs and a lot of track people will go to 100ish ft lbs to stop them from moving

Your subframe could be shifting too. I make rigid collars to lock them into place.
I usually overtorque my adjusters by about 10% to keep them from slipping. Using OEM specs, they definitely move.

I think it' interesting how it changes back to the same result. It only pulls to the right, never any other way. Going to change out all the lock nuts, maybe front right camber nut is toast and slipping?

Take it back to the last shop and compare print outs of last geo,would that not pinpoint the faulty area to look at ?

Yes, this 100%. Buy all new lock-nuts, also go to a real race shop if you are not already.
