You didn't say what year your blade was...unless you meant it was 2007

Anyway says 2.5 Bar front and 2.9 Bar rear.
1psi = 14.7psi atmospheric so...
Front = 36.75psi
Rear = 42.63psi
If the bike doesn't feel right, could well be down to the tyres you got on it?
I run 36psi front on mine and just over 40psi rear...any less than that I find the rear slumps and slides...and more than that and the rear end skips over everything.
You brought the bike from new or 2nd hand?
