How much fork oil does each fork take - 2008 kawasaki Vulcan 900 Custom

The amount of oil that goes in the forks of a 1982 Suzuki GS 750T will depend on the type of forks that are installed on the motorcycle. It is important to use the correct amount of oil to ensure that the forks are functioning properly.
If your Suzuki GS 750T has standard telescopic forks, you will need to add 10.8 ounces (320 mL) of fork oil to each fork. If your motorcycle has air-assisted forks, you will need to consult the owner's manual to determine the correct amount of oil to use.
To add oil to the forks, you will need to remove the fork caps and use a fork oil level gauge or a piece of wire to measure the amount of oil in the forks. If the oil level is too low, add oil until the forks are filled to the correct level. If the oil level is too high, remove excess oil until the forks are at the correct level.
I hope this information helps! Let me know if you have any other questions.

The fork oil does not have anything to do with the kind of engine do you have, 2t or 4t. Doesn't matter.
You need to replace the fork oil, you need to know the year of the fork. means, you need to know if it's a bladder or non bladder fork.
oil height of the bladder fork is approx. 70mm, non bladder forks run about 100mm oil level.
oil amount is about 530-600cc per leg

Remove forks from bike, with each fork remove end cap and drain plug over a bucket drain oil from each fork reinstall drain plug on lower leg, replace oil thought top of the fork to spec, replace end caps and bleed oil from forks

To change the fork oil, look down on the lower part of each fork leg just above the axle on the backside of each leg and you'll find an Allen plug or small screw. Take this screw out, hold the front brake and push down on the front forks. The fork oil will come out of the tube. Do both sides at the same time. Once you get the oil out of them, reinstall the drain plug. Then, take the large hex cap on ONE TUBE AT THE TIME and pour the correct amount of the correct fork oil into each tube. There is a specific amount of oil that must be poured into each leg. Since you simply drained your forks instead of disassembling them, you should use what is known as the "Wet" quantity of oil. I'm pretty sure your bike takes 9.0 ounces of oil in each leg. Call your local dealer and they'll tell you how much oil to put in. Your bike came from the factory with "Type E" oil in the forks. The viscosity of the oil determines the dampening effect of the forks. Heavier oil will stiffen the front forks, a lighter viscosity of oil will make the front end softer. You can check the Internet for fork oils and they should give you a comparison of what weight oil is equivalent to "Type E" oil. I think PJ 1's 30 weight oil is the same as type E Harley oil. Use only "fork oil" in your front forks as it has special "anti-foaming" agents in it. If the oil foams up, you'll lose the dampening effect in your forks.

Good Luck

well first of all,,,,,you dont just top up the fork oil,,,,
you drain it all out and refill it with clean fresh oil....
the reson for this is,,how much oil is left in the forks?
if you over fill them with oil you will burst the top fork sead?? bad news that is! so find the drain plug (a nut or screw) at the bottom of each fork leg and drain all the old oil out first,,, then remove the fork top plug and tip in the right amount of the right grade of oil into each leg,,,then let it stand for a fuw minuets,,for the air to come out,,,do up the fork top plug and push the forks down a fuw times before riding it to spred the oil around inside the forks,,,oh,,by the way,,,change the fork oil yearly,,,,,
