It can be as simple as a slight burr or piece of debris caught in your seal. You can try a 3x5 notecard wrapped around your fork leg and GENTLY work it down past the seal. Also inspect the fork tube closely and if you can see a visible burr remove it with very fine sandpaper or emery cloth.

If you have to remove the fork because it is leaking elsewhere (and you have checked your drainplug) that is rather involved and requires you to suspend the front of the bike to remove the front suspension. How far apart you take it depends on what you have to fix though.

How do I refill my fork tubes with fork oil


Begin by loosening the upper triple-clamp pinch bolts and breaking the fork caps loose while the fork is still held by the lower triple clamp. You will need to remove the caps to refill the fork tubes with oil.
Determine if the fork legs have oil drain plugs near the bottom of the legs. If they do, you are in luck and will be able to change the oil without removing the fork legs. Put old newspapers on the floor under the front end. Place a drain pan under the fork legs and remove the drain plugs, one side at a time. Hold the front brake and push down on the fork several times to pump the oil out. When oil stops coming out, reinstall the plugs using new sealing washers.
Without Drain Plugs
If there are no drain plugs (look carefully), you'll need to remove the fork legs to drain the oil. At this point you can decide to have it done professionally or do the work yourself. We'll cover the main, basic steps. Refer to a shop manual to learn all the exact procedures involved. Some motorcycles may require fairings, handlebars, etc. to be removed.
Support the motorcycle either on the centerstand (if equipped) or by using a motorcycle jack under the engine. If you use the centerstand, you may need to place a sandbag on the rear of the seat, hold the front end up using straps from the rafters, or support the bike underneath the engine. Use tie-downs to steady the bike on the jack. Grasp the lower fork legs and try to push and pull the fork toward the back of the bike and forward to check for loose steering head bearings. Inspect the pleated rubber fork boots, if equipped. Check for signs of fork oil leakage and any grooves in the fork tube wear surfaces where the seals make contact. Also check for looseness between the fork legs and tubes that would indicate bushing wear.
Remove the front wheel and axle assembly. Support and tie the brake caliper(s) out of the way. Remove the front fender and speedometer cable, if equipped. With the fork leg fully extended, remove the top cap from a leg. Be prepared as there may be some spring pressure pushing against the cap.
Loosen and remove the pinch bolt from the lower triple clamp and lower the fork leg. Note any shims or washers and spring. Turn the leg upside down in a drain pan until oil stops flowing out. You may have to move the damping rod in and out to get the oil out. Repeat the procedure for the other side.
Reinstall the fork legs and other removed components in the reverse order of removal.
All Models
Add the exact amount and type of oil recommended by the manufacturer. Some motorcycles call for the use of a dipstick to determine how much oil to use instead of just pouring a certain amount of oil back in. Follow the manufacturer's shop manual recommendations.
Carefully install the threaded top caps by hand to avoid cross-threading. Tighten the pinch bolts and top caps to the factory-specified torques. After the brakes are installed, pump up the lever until the brakes feel normal again. Once the bike is assembled and on the floor, push down on the front end to verify the suspension's response. Turn the steering from its left to right limits to ensure nothing is binding, and check all controls including the throttle for proper operation.

Ive just replaced the fork seals on my non ABS 1990 st and noticed that one fork leg rebounds faster than the other. Is this correct and is this why the fork legs are of different inners?


Uneven rebound is caused by unequal volumes of damping oil in the legs or a broken or weak spring. Not sure why one inner tube is different, but it may mean the quantity of oil differs in the left and right forks?

I re-categorized to Honda Motorcycles for you.

Oily fluid leaking from front suspension forks. Both sides leaking how do i repair this.


Replace the Fork oil seals. It will require you to support the bike from the headstock and remove the forks. You will also need to know the correct amount of fork oil to put in each leg. Buy the manual for your bike (whatever it is) it will cost about 20GBP. a new set of forks will cost considerably more.

How much fork oil do I put in each leg of my zephyr 1100


Is you have taken the forks apart and changed the fork bushes, ie forks are totally dry, you will need about 520ml in each fork leg. When refilling and will the springs removed, add about 550ml per leg, the stroke the forks numerous times to expel any excess air. Then with forks compressed the oil level should be adjusted to 119mm from the top of the fork to the oil, ie the air gap to the oil. The add springs and spacers and reassemble.

Front fork seal is leaking


Yep, drain the fork oil, raise the front wheel in the air, remove the front wheel and axle. The nut to remove the lower leg is at the bottom, hidden by the axle. If it still leaks after seal replacement your fork tubes and lower leg sliders are worn out. Reassemble and remove the top fork cap. Pour in the correct cc of fork oil and ride.
