Mick I can't join you but that sounds like a lot of fun. I also ride a Blackbird and those open speed limits in NT sounds like the perfect place where the Blackbird can be let loose.
I know that sustained periods of high speed eats those rear tyres much more than normal. Last year we did a quick lap of Queensland "5000km" and I trashed a rear tyre and chain. Watch out for the Roo's
Travelling by yourself is just as much fun if you stay in country pubs and mix with the locals.
Go get 'em
