Seven years ago I re-built my mate's 'Old Nail' R80/7 after he got it back from his brother-in-law who ran it with a gearbox output-shaft bearing having failed (numpty thought that the clutch was slipping
).
As it came home:
Owing to a tight budget, my mate suggested that we re-build the gearbox rather than source a replacement.
After a winter spent in his garage, it finally emerged looking like this:
Seven years on and the hit & miss gearbox re-build, being more miss than hit, finally just got too likely to let go and James Sherlock supplied an exchange reconditioned gearbox.
I've had the bike in my garage for a week or so and with the gearbox out I've taken the opportunity to attend to the last seven years worth of cosmetic wear and tear.
Now into the gluing it back together phase, always the best bit.

Your a quality mate to do all that work
