If I understand correctly, the Guzzi and BMW gearboxes were modified simply by machining new gears. I wonder if it would be possible to (a) get the data for cutting the gears or (b) if he would be interested in making some gears for sale. The new gears make these gearboxes practical for use, particularly with the low(er) rpm of the multicylinder industrial engines such as my Daihatsu D950.

Hi ,
Well, my first diesel bike (daihatsu) was build with a Guzzi500 gearbox.
The beauty of this "powertrain" is that a single pair of cogwheels sets all ratio's ...
There is even no need to dismantle the actual gearbox for that ! The box I used even had a kickstarter
These bikes are very cheap: I've purchased 2 complete Guzzi500's for Hfl 700,- (about 300 Euro)
The drawback of the Guzzi box is also obvious: the swingarm is -at least for machines > 250kg- too weak and "she" never made it to our RDW license_plate (?) registration.
(I 'm thinking of buying some chinese "punsung" lightweight diesel...for this
The BMW drive-train is much more stable (although it's certainly not what it used to be !)
The 5th gear leaves "some room" for a 1:1 set of cogwheels.
The removal of the fixed (heat shrunk) cogwheel was a true pain in the a...
The production of the cogwheels was not really a problem and I've heat_treated the cogwheels (Arne steel) myself...
and I'm no engineer (that answers the question of selling cogwheels
To be short: the machine does not run Yet...I hope to find some time later this year to "finish" the job...
And if the gearbox survives the first real tests...and I may live to tell... I'll hand over the "machining data".

Really impressive The bikes just seem to keep getting better and better 
Good thinking on the gearbox, multi cylinder diesels don't need to do big rpm's and can be configured to run at highway speeds in there optimal power/economy band. The ole singles are a little different
you set them up to run just under max rpm 
Nice bike - look forward to seeing the finished product.
Cheers
