TOPIC:

Im doing up a GT 750 (kz750-p1) and it has pressurized forks, i'm wondering what will happen if i do away with the pressurized system and leave the little ports open to the atmosphere, as i want an uncluttered looking front end and would like to get rid of the manifold that links the two fork tubes together.

any thoughts on the idea and how it will affect handling?

Don't leave them open to atmosphere, plug them, then it should be fine (if you don't weigh over 200 lbs anyway).
I think a set of Progressive fork springs might work better with 0 air pressure though

I'm not to familiar with the GT750 in how the forks are set up since it was a non-US model.
But if it's anything like the GPz models offered in the US and had the equalizer tube (ref# 51044 in the pic below), then you can't remove that setup since the upper fork tubes have a corresponding hole in them that allows the air to "balance" between each side.
Removing it would leave the inner prings/oil/bushings/etc open to the elements and condensation.

My Honda has a Schrader valve on top of each fork. Use a hand held
bicycle pump and a guage to set them up. No manifold. Very clean
looking.

My 80 LTD forks each had their own Schroeder valve also. I busted up one valve so I just used the caps off a standard set of forks.
