Firstly, thanks for the replies. I ditched the el' cheapo comp. tester and got a good quality one.(thanks to a previous post clearing that one up) Comp test now shows 100 psi (f) 105 psi (r) cold engine , WOT. Is this still within specs? Bike is MC21 22000 km.
Thanks for the air filter advice, I'm having trouble locating a stock or aftermarket element, Uniflow does not fit. Any help in this area would be appreciated.
Any aussies please contact this means ref the above, located near Brisbane.

First track day on this bike tomorrow, can't wait!
