Mine ran stock 200 gearing with the short fourth with one of those SIP boxes. Mine's a 60 mil crank version. With a RHS RZ pipe thing, runs the same gearing, and is much nicer to ride.
It has never felt over geared, even two up.

Late mick

Names not Mick ?

The late gearbox will give you 5.2:1 (or thereabouts). Quite short gearing for a "Torquey" engine, the P2 gearbox is more like 4.7:1

Maybe a longer rod would be a consideration as well ?
