    Nice one Mick...

    yeah, I think that's why the TX seal is so bad, just too much lost volume in there. Ironically enough, it's less of an issue on the long-stroke mk3, but it ruins the mk1/2.

    On my SR (mk2) you can't change the rod length or you mess up the SR mechanism (which relies on the rear edge of the piston skirt being in the same place), so I simply switched to HW nose, shortened the port 2mm, and it's sweet as now... stroke has gone down from 82 > 77 (seal height + nose) but the SCR is actually higher, and so it feels much softer.
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    All Diana type seals seem to suffer the same loss, Jon

    I remember someone describing how he filled the central void with liquid rubber to raise the SCR on a TX, I can understand why now.



    All the best Mick

    Excuse me, please, for reviving this thread.

    Just searched it out and thought I had better ping it up to page one for a while (a) as I have had the pleasure of using this gun at the April and June Bashes and IT IS SUPERB and, (b) having just got a TX, wanted to refresh myself with the details, folks.

    May help a few others, too.....

    Tuning an SR? Isn't that a bit like having a dog and barking yourself?
