My 390 does 80 at 3kRPM, and I checked it against GPS.

Your speedo may be overreading...

Agree with above.
80mph at 3k rev with 'standard' diff. ratio

definitly the speedo is overreading, its easily changed tho' just fit a different speedo drive adaptor in the gearbox

I'll bring a selection along to the next meet, its easily changed

Why not check it against a GPS..

If you want your speedo to read right take a look here at what's required:

I did this to calibrate my speedo after upgrading wheels to 15", replacing diff and G/B. IMHO it's easier and cheaper to do this rather than trying to get the ratio correct at the G/B end. Speedo is now spot on as measured against my satnav GPS.
