    Sorted the valve guides and now the gearbox has gone weird on me. It
    drops out of gear in top gear only and more often the hotter it gets.
    For the first five minutes of riding all is well then it just gets
    progresively worse. If I hold the the lever up with my foot it stays
    in gear.
    Any ideas? I'm happy to strip the engine but gearboxes scare the hell
    out of me.

    I may be mis-remembering but there's a modification to unit gearboxes
    which is basically a spring loaded plunger mechanism screwed in
    underneath to stop this happening. I don't know who manufactured this
    or even if it was an official triumph mod - try asking rocker box
