Fork problems So i ride a 1995 m900. I got the bike trashed and it had no oil in the forks. So i filled them to the proper level. Well of course they leaked. So i got some cheap ebay seals from pyramid parts hoping they would sure the problem. Wrong

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.

Normally, the fork oil level is set with the spring out, and the fork fully compressed. Fill the fork to 110-120mm from the top.

G'day. A couple of suggestions-
Damage to the fork slider-chips or dings.
Too much oil in the fork on re-assembly can cause the seal to go.
Worn or loose fork bushes will flog the seal prematurely.
When you transport the bike-if you don't use a seal saver can pop the seals.

So let me help with these.

Be sure that the fork slider is not scored,dinged or damaged on th surface.

A good double check of the oil quantity is to ensure that when you have re-filled the tube with oil & primed it(worked the air out of it), the oil level should be 100 to 110 mm from the top of the leg to the oil with the fork fully compressed. If the level is less than this-drop it to 100mm.

To check the fork bushes-try pull on the front forks front to back(wobble) & feel for looseness in the bushes.

And finally-When you transport the bike-put a chock(I use an empty 5ltr oil container-but you can buy propper chocks from the bike shop) in-between the forks at top of the front wheel .
Now when you pull the front end down it will stop on the chock & stop the front forks being under excessive compression for extended periods-so it saves the fork springs from sacking out too.
I hope this proves helpfull.

Std fork oil grade all around is 10W, depending on bike usage and preference, it can go down to 5W or up to 30W.
Oil level usually run from 175 -250 cc per fork, too much oil will cause fork to be stiff, not enough can damage fork seal, so go by trial and error but the amount should not run far from above numbers. Good luck!

have you fixed the leak ? if so then you can just pull the handle bars and undo the top cap on the forks you may hear air escaping when you do this but thats ok it shouldn't be there any way adding oil is easy the right amount is the trick (tool required) looks like this available at a local bike shop near you depending on your skill level and what you are doing with the bike the right type and amount of oil in the front forks can dramaticaly affect the bike handeling Good Luck ride safe

My repair manual and local shop specify 15-16 oz per tube. weight can be changed to suit your ride quiality preferences.

This all depends on what size forks you have, but a good rule of thumb is 120ml. After that then what you want to do is to ride the bike and make adjustments to your front end until your liking.

its 120 mm or 4.7 inches from the top of the fork
Some measure the oil quantity and fill the fork up, some fill the fork up and measure the oil level. The most correct method is to measure the level, I guess, but many guys measure in quantity.. both ways work well.

they leaked just as bad. Figured i must have torn them installing them even though i followed my book instructions and even put a condom over the slider end to ease the seals over. So i tried again with the pyramid parts ones this time they turned INSIDE OUT when i came down from a wheelie. I order some from dennis kirk and they take 4 weeks to get here. I go to put them in and they are the wrong size. Can anyone reccomend where to get seals for my showa non adjustable forks? Im having bad luck so far. The dennis kirk ones are part number 14-9926 maybe they are for the marizochie? forks. I got my seals from here: http://www.racetech.com/evalving/eng...ngname=english http://www.race-tech.com/,,,
