Tyre pressure/handling question?

[SUPERSTARDJ01]

Hi,

Would 4psi down on front and rear tyres make the bike handling ****e? Because the ZX felt as though it was running on a flat, stopped checked front tyre no puncture no nails only 4 psi down, so pumped it up and still the same although if I go faster the feeling seems to go, the brakes are sqeaking but it's not hard to push at all, could the brakes be binding making it pull slightly to one side, giving the feeling of a flat tyre?

You can probably notice 4psi

the brakes binding cannot make it pull to one side, neither does a flat tyre

4 psi is probably enough that you'd notice it.. Not sure why your bike is handlnig strangely, but check the basics so

1. tyre pressures
2. type profile ( i.e. not gone square )
3. Suspension settings - have you tweaked or fiddle with them and induced the handling characteristic that way.

wheel alignment ?
twisted forks ?

only things i have experience that make the bike go to one side

Mirrors ok?

check the head/wheel bearings

Wheel bearings seem ok, suspension not touched, tyres not squared, head seems to have a little movement, how do I check forks are not bent?

4psi down on the front would feel pretty horrible, are you sure the extra air is still in it?

Yep pumped up riden left for the day re-checked with digital pressure guage and still on 36 psi, I have how-ever noticed my wheel is pointing slightly left, so forks maybe twisted slightly.
