Tyre Pressures and suspension set up

Hi guys.
Anyone got any other ideas on tyre pressure firstly ? The manual says 34 front and rear.....seemed a bit low to me but then I have been riding sports bikes for 10 yrs

Also, are there any suspension set ups worth trying ? Dont like messing with the suspension so would prefer something tried and tested I weigh about 12 stone if it helps

Cheers guys
