Sounds like you're on the mend. Thanks again for letting me wind up your beautiful Commando at Miller.
The gearbox you are referring to is a Nourish Triumph 5-speed with a custom mainshaft for Commando clutch, etc. When I was looking to replace my 4-speed I phoned Dave Nourish, and he told me he didn't have any more mainshafts, and they weren't in his future to make more. And that was 3 years ago. From everything I've heard he's on his way out of biz - used to have 2 engineers with him, now just him filling orders on inventory he has on the shelves. This is the way it goes with our beloved suppliers as they retire.
Now, if I may - I have NEVER felt anything like the TT box. It's a dream. It one of those things you never knew you needed until you have it, and then can never go back. When I was offered to ride Bruce Yoxsimer's G50 in the back of my mind I mulled how I was going to handle running a Quaife again. Fortunately it was a well sorted box and caused no problems. But I do think the TT is worth every penny, and Bruce Verndon is a stand up guy. Just keep your eye on the US dollar vs. NZ Dollar, and strike when the time is right!
You can ride my bike next time!
