HI mark,
I use a set of tyres every meeting, thats 3 days of hard riding and the tyres are rubbish afterwards. I put a new set on after the test day new for qualifying so 1 qualy and 3 races, by the end of race 3 they are well past there best. I then use them for any track days and the following test day, they don't do anything wrong really but they are not as fast.
28psi about right
my bike had 81bhp after I put the 900 back in it.
