Can you tell me how much fork oil i have to put in my gsxr 600 which is a 2001

Hi Alan, What I'd do is when I'm buying the fork oil I'd ask the person serving me OR if you already have the oil just ring the local Yamaha dealer and ask them.........CHEERS..

This volume of oil is shown in the service manual, on one of its specifications pages. If you are going to work on your cycle, you need to get a service manual.

For a bike of this age, there should be a free download of the manual. Find it by googling "service manual download Suzuki 1995 GSX-R 1100w."

Following this advice, I found this link to a free download;
http://servicemanualsgsxr.com/suzuki-gsx-r-1100-1993-1996-service-manual/. After downloading the manual I found the fork oil capacity on page 1-11, 425 ml.

However, I think you will want to know how to get the oil in and out of the forks as well. This info is found on pages 7-22 to 7-29.

Enjoy the experience.

Remove front wheel, brake calliper etc . Undo top and bottom yoke pinch bolts and slide out fork leg. Clamp chrome tube in a soft jawed vice and remove top nut carefully as it is under some load and will fly away, (but its not too much you can hold it with your hand). Tip out remaining oil slowly so as to not loose spacer on top of main fork spring. Clamp lower aluminium leg in vice by calliper mounts and remove allen screw in extreme end (if the wheel spindle was in you couldnt see it) This is the only part that might be a problem as the inner end may turn. An impact wrench may help or if not a simple broom handle shoved up the other end is often enough. Once this bolt is removed the leg will split. Now lever out the dust cover to reveal the wire circlip holding in the fork seal. Remove the clip and lever out carefully the old fork seal. Fit new seal using a large socket and mallet or something similar and reassemble in reverse order, not forgetting to add correct amount of new fork oil.

Have you tried to get Haynes manual for that model? or have you try to Google it?

if you go to CARL SALTERS MANUALS you will be able too down load all the service manuals for the GSXR600 1999 for free and it will give you exact messurements plus diagrams it has absolutely everything that you will ever need or want to know wish you the best with your bike have a 750 gixxer myself what a machine take care bud

450 to 480 ml per fork tube. i have 490 ml in each of mine. you can fit up to 525 ml if you want them a little stiffer.

If you never have put for oil into a set of forks, yes you have to check both forks. I would suggest treading lightly. If you have time and a place to block the bike as well as a manual you can do it.
Are you adding oil because the seals are leaking or do you have excessive stiction in the fork? If the seals are leaking, you will have to pull the forks and add new seal and put in exactly the right amount oil.
Do you have air seat or is it a closed fork?
For you en500 you should have a volume of oil in your service manual.

ello m8,, from a 500ml bottle of medium grade fork oil,, pour half of that bottle into each fork leg,, or if u have a litre bottle pour just over a quarter of that bottle into each fork,, cheers

The oil can be drained removing the NEAS system valves ( 2 allen bolts ).
System contains 456 cc ( 15.4oz.) oil in each leg.
the oil-level measured from the top of the COMPRESSED leg is 107mm.
To measure:
- have an oil-suction pump
- Make a tube with a stopper at 130mmfrom the end.
Drill a little hole ( 3mm ) at 107mm (4.21in) of the stopper.

More oil will tighten the suspension, less will soften it a bit.
Oil type: SAE15

Hope this helps
