Hi guys, I got a pair of GSX750 air assisted forks and was wondering if anyone could tell me how much oil I should put in each fork and what air pressure I should use?
Thanks in advance.

Hi Mr. baldybongo,

I can only offer you general suggestions and encourage you to check the manual. Looking at a 16 valve GS750EX manual it says capacity is 191ml, the level is 227mm (this is the more important measurement, must be within 1mm of each other), standard air pressure is 7-8psi. I used to run about 15psi in my air forks until I installed Progressive springs. Now I don't use any air at all.

I want to dump a TON of information on you and share some GS lovin'. :D

I just stopped by to welcome you to the forum in my own, special way.

Thanks guys for the terrific welcome:lol: The forks I have, have a connected fitting on each fork just above the bottom yoke. When I removed it to get the yokes off I saw a small hole on each fork where the nipple fitted. When I undone them I heard the air come out so I guess I need to refit and put air back in after?
Hope this makes sense. Just wondering how much air to pump back in.:confused:
Think its an early 80`s Katana?

If you don't know for a fact what year and model bike they are off of, then it is impossible to know how much oil they require, and what the max pressure rating is.

As far as I know, every GS with air assist forks could run them up to at least 15 psig, some up to 30 psig. Level varies with each model.
 
No adjusters on the bottom, just that fitting on the top? Cheers.
