I remember that back my the helicopter in design spaces where zero lash was required we would use a pair of gears clocked slightly off so one half would match the leading edge of the cog and the other would match the trailing edge to simulate 100% mesh.  Nifty way to eliminate lash but it did require maintenance and adjustment and did tend to promote gear wear.  I am sure in a motorcycle drive application you'd be changing gears every couple thousand miles. 

Clog wheel train.

Where is the driveline lash mainly generated ? Not pinion/crown wheel, or splines anywhere so is it the gearbox driving dogs or what. I, like most guys can ride around the issue, but my mates R1100s BMW seems to have virtually none. I appreciate that the Beemer fires at even intervals every 360 deg. but does that explain the difference ?

from what I can figure it is in the gearbox, not in the final drive.  That is just supposition from feel so I could very well be wrong.
