Joe your a bloody champion mate!
New bike, not quite set up the way you wanted, things not going right from the start, and you still wanted to keep adventuring. Thats the way!
And good on ya for posting up the way you felt about it all. Made for good reading.
Don't worry -- all those little head games happen for me too -- if something is not right on top of the bike, I for some reason think that will affect whats happening below the bike. Generally not true is it!! You've learned from this ride, and taken away a few good experiences and lessons. It is all part of building yourself.
Always looking forward to the next great Aussie ride report, so start planning the next trip!!
