Hi chaps, been hunting high and low for a definitive answer but just seem to be going round in circles, lots of folk seem to be plucking random figures from out of thin air but none ever really seem to tally up “so, my question is” does anyone know for a fact the correct/factory nitro pressure for the aforementioned 99 plate GSX750F rear shock ?

Cheers, Jozzer Thumbs Up

I can't tell you the exact pressure but it would be pretty low.
The nitrogen is only there to stop oil aeration and nothing else. You would likely be fine with around 10 or so psi but you do have head room to experiment.

If whatever pressure you choose blows oil past the seals, drop the pressure 10 psi.

I've recently rebuilt a KLX300R shock and the pressure required was a massive 142 PSI.
A very quick google search (which I assume you have already done) seems to suggest that your bike requires around 180 PSI but we all know how wildly inaccurate internet advice/info can be.
