Welcome to the forum, it's usually an on going 'restoration' with as old as these bikes are !
How is the parts availability in N Z ?
It's pretty common to have the odometer fail, the repair has been covered here, only requires a few dabs of adhesive on a gear or two .
To the best of my knowledge, you are the first member from New Zealand, from the pictures I've seen, it's quite spectactular landscape ! So we're expecting pictures of your rides !
