I have a 98 suzuki gs500e and plan on replacing my fork seals. I was wondering if anyone knows hom many CCs of oil per fork to fill em with. I have the OEM seals and oil but the parts/service guy did not want to look it up for me.
any info would be great.
thanks,

Oh for christ's sake, buy a manual. That, or fill the forks all the way to the top with spam. Spam spam spam...
If I don't have a manual I usually measure what came out and add the same amount back in.....
Just fill em to the top and take a little out to get the caps on. That should do it.
Airhawk - Nice link!

That should address all his forkin' issues...

And don't forget to secure the chow line.

This "Google" thing - if they would make it a bit more useful finding things, I believe it just MIGHT catch-on.
Google?

Nah, I'm a Dogpile kind o' guy.

And LR, I wasn't trying to throw a >damper< on the thread...
I think we need an MO article on how to fork correctly.
Are you guys gonna get some Work done today, or just sit here on MO - Forkin' around?
I'm not at work. So I get a break :)
When you google the correct amount of fork oil to add, it will probably come with a measurement, something like 191 mm or the like. That's the distance from the top of the fork to the oil, usually with the spring in and the tube fully extended. Go to your 1$ store, buy a spray bottle, remove the spray mechanism, cut the tube that extends down to the length listed. You should be able to insert the tube into the fork, and if you can spray any oil out, you've got too much in it, otherwise if there is no oil at all on the sprayer when you remove it you may not have enough. Despite the helpful crowd here, don't fill it to the top of your fork and replace the cap, unless you found the fork seal changing process enjoyable.

A skinny turkey-baster works better. You just graduate the side of it with a sharpie in 5mm increments; squeeze the bulb, dip in to the corresponding mark, and let go of the bulb. Eazy-Peazy. If you're within 5mm of the spec-height, you're golden.

This ain't Rocket Science, after all.

I ah..... wouldn't use it to baste a turkey after this, though.

And if you DON'T have an oil-height spec; you gotta measure-out the CC's. Find a measure-cup in the kitchen-supplies section of Mal-Wart that's graduated in "ml ". One ml = One CC. It's a bit cruder this way, as you can't get it as exact as using those spendy forkoil measure-cups you get at your local moto-dealer.

But this ain't Rocket Science.

10CC's more or less won't be felt by anyone short of Casey Stoner or Valentino Rossi.
So it pretty much ain't rocket science?
Pretty much.
