Why would you want the latest vavle? My old Harrier was as consistent on my New X. The only reason I had mine regulated was to increase the shot count.
Can a 4yr old Harrier be retro-fitted with the most recent valve and how mutch would it cost?

I suspect that the latest valve can be fitted - but have no experience of this - a call to Daystate will solve it for you.
You could ask them what the benefits over the old valve are - I'd be interested too.

The later valve gives a flatter power curve, but with less usable shots per charge. If a conventional valve gives a curve like a gradual mountain, then the later MK3 valve fitted to the Harrier & X tends to behave like a table top mountain with steep sides! This is why if you overfill a Harrier X, power drops dramatically.
The earlier guns can be set up to mimic the later developments but complete change over wouldn’t be economical as it would mean a change in valve body, valve all the springs and some work on the transfer port as it is smaller on the later set-up.
Hope this helps.
