How do i change the fork seals on a kawasaki zxr750 1989

NO. IF they are leaking, either they have been overfilled, you nicked the seal during install, the forks have some small surface defect in the seal contact area. If you did not replace them, they need to be replaced.... without regular usage.. they get dry, shrink, sometimes the seal lips crack

I used to run mine as recommended in the manual and that is at 7psi or 0.5 kg/cm3. I would recommend using a low pressure pump (not the ones at a service station or garage) as the air chamber in the forks are very small and pressure up very quickly. Over pressuring can blow the fork seals. I found that as long as you don't exceed 10psi it is fine.
I do have electronic copies of the manuals that I can email to you if you want them. I can't attach them here so post your email address in the comments and I'll get them off to you.
Hope that helps,
Steve

If you are not VERY mechanically inclined...and have the special tools required... .please take this to a professional!! it will be less expensive in the long run.!!

It takes some special tools that only dealers have.

Replace Fork Seals with great aftermarket kinds. I replaced mine with AllBallsRacing for seals. Call them up or search online.

No special tools other than maybe an air-impact whench to remove the Allen bolts in the bottom of the fork sliders. These hold the botom of the metering rods into the forks and will spin if you don't have Honda's special tool which fits down the inside of the fork tube. Air wrench spins them off no problem.

V65 Sabre has fule filter behind battery and fule shutoff valve under seat.

Loosen upper triple-clamp pinch bolt before trying to remove fork cap.

Drain oil out of fork, then remove axle and access the metering rod holder bolt at the bottom inside the area whre the axles goes. Use an air wrench and appropriate Allen bit.

Remove fork cap, being careful of the spring pressure.

Remove fork from bike and take out spring and metering rod. Pry dust seal out of fork slider and use snap-ring pliers to remove retainer from beneath dust seal. Use fork tube to hammer seal and slider bushing out of fork slider.

Replace seal and use old seal to cushion it. Make a fork seal driver from split PVC pipe and hammer seal and slider bushing back in. Remove old seal and replace retainer clip. Install dust seal.

Reinstall on bike and install spring. With bike properly supported, stand on pegs and use ratchet, extension and socket to apply pressure to spring and thread cap carefully onto top of fork tube. Reinstall metering rod holder bolt in bottom of fork using thread-locker and air-wrench. Don't over-tighten; just ue high speed to conteract tendency of metering rod to spin inside slider.

Remove fork cap again and fill to appropriate level with 5 weight fork oil (Pro Honda SS-7 or equivalent). Use turkey-baster to remove excess oil to proper level (5 1/2 to 7 inches fully compressed depending on damping quality desired).

First, go buy amanual ,clymer or haynes shop manual from a dealer or sent a from J&P CYCLE or from DENNIS KIRK , then when you got to work on it you will have somethnig to go by, and not trying to guest if your doing it right. J&P-1 800-318-6847, DENNIS KIRK-1-800-969-7504, and tell them what you need.

You need a manual and there are special tools required to change the seals. Let the dealer do it.

hi there,,if u can see a air valve on top of the forks, then u can use a bicycle or foot pump to squeeze a bit more air to the fork,, or if there is an adjuster on the fork,ie, a plastic lookin cap with 1 2 3 4 and a arrow on it u can turn that to a comfortable position,, if there is nothing u can see, then u either have not enuff fork oil in each fork leg,,or if there is enuff,, u will need to change the grade of fork oil and replace wots in it,, so id say a more harder grade of oil,, usually there isnt enuff oil in the forks to make it dive into the front wheel,, try topping the oil up,,with about,4or 5 egg cup fulls of oil in each leg,,if nothing has made any difference,, put in another 4 or 5 ,,,any probs on how u put oil in2 the legs ,please do come back in ,and il tell u how 2,, im assuming u do no,, ok ,,cheers
