Dazzer, the rectifier on the Z is not the same as the others. The pins in the reg are very small , the X / R ones are about 5mm as per normal connectors.
If I was going to do the trip that you are planning I would mod the existing reg as Stoic bloke did on his and use another rectifier, ie cut off the end and solder the leads of another on. I cannot remember which one it was but I think that it's another Yammie one but with the wires going into the actual unit itself, so should have a bit more length to play with.
I personally feel that there may be enough length in the loom to unravel it from the strapping and mount it underneath the bottom of the steering stem. That's what I'm going to investigate anyhow. Have a search on the reg / rectifier threads to see Stoics mod.

Cheers.
