I've done a search and found hundreds of threads but none give the actual gear ratios or point at a site/document that does.
Can anyone help?

Steve,

Heres one that does it all...and its free.

Calculates max speed at redline in each gear ( km/h or mph), km/h (or mph) per 1000 rpm for each gear, rev drop between gears, etc ,etc.

www.locost7.info/gearcalc.php

Hope this helps.

Thanks for the calculator.
That should be OK but I still need the actual ratios to use in the calcs.
