Sorry - I must be fick or somefing...to recap:

My '28 zings along nicely up to 11,500rpm or so - as high as I've let it rev in top, this equates to ~190-200KPH, though not exactly sure as the digi speedo stops at 180 KPH. So no speed restriction.

My '28 has fully functioning clocks etc. so the splice has not been done - RIGHT?

Running original Card Key.

Under this state what is the max power I could expect?

It sounds like claimed 57 BHP is not possible, UNLESS it has a MC21 flywheel (which I don't know) - I'm e-mailing the previous owner to see if he can tell me anything.
