Undo.

"Dismantled?" you say? Yes, and here's how & why.
After the mock-up was complete, we brought the "bike" back to my garage and, after immediately turning the handlebar back the way it's supposed to be, I took the whole thing apart again.
It took me just under 3 hours, no rush.

As I did all that, I put every tool I used in a box so that by the end I had a good idea of what's needed for travel and maintenance.
I'll soon go about making a toolkit just for this bike before the rally in September, based on what's in the box.
