Finally I am getting back into this project for our winter here in NZ.
I have finished the exhaust, rear brake, gear linkages, rear sets, seat mountings, rear mudguard, rear lights and relocated the battery to a new home made battery box. I had mounted it in the rear cowl, but changes to the order in which components are fixed to the rear made it a pain to be quick to access - especially for trickle charging the battery. As this bike will be a show pony and not ridden as much as others in the fleet, I decided to re-position it. Am now working on the electrics and integrating the new combined speedo and tacho to the old BMW electrics. Thanks to RBM for all the help on that topic.
