As far as I am aware, the Road king doesn't have air assisted forks. As you have a Harley why don't you go to your local dealer and ask them. But, as Harleys are probably the most modified bike around, it may be worth looking on the forks for a tyre type inflation valve.

SOURCE: 99 CBR 900 Front fork seals

If the seal has been cracked by the cold weather it should be replaced. For someone mechanicly inclined and with the proper tools this is not a hard job. For the novice it can be one of those times you could have sent it to the shop and spent less time and money, and gotten better results....
As to a seal conditioner, the seals today are generally made of synthetic material. No "conditioner" will work. If the seal is made of rubber you have a 90% chance that a product called 'MARVEL MYSTERY OIL' will solve the problem. This prouduct was created in 1917 and marketed in 1923. Google the product name for more hystory and uses today. Basicly, the oil causes rubber to swell. This tightens seals and thus fixes the problem. Most any good auto parts store has this stuff on the shelf. By the way, if the bike was purchased new, wouldn't this be a warranty repair?

The forks usually bend well before the frame.
Take the forks off the bike and turn the chrome part in the fork leg and you will soon see if they are bent.
If they are only slightly bent a dial gauge will help.
Dont even think about having them straightened, get new ones

Keep having leaking fork seals.have replaced seals and oil after every ride lately.(4)have tried two brands of seals last time disasembled whole of forks cleaned every part,shims everything and had...


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.
Kind regards Andrew Porrelli

Ive got a gl1100 1982 with air front suspension q-what is the best way to change the front fork to a convensional spring fork and what forks would be the best ?


Hello and thanks for the question,
Your 1982 GL1100 has air assist type of suspension. It has springs in the front as well as the air pressure. This is a heavy bike and the front forks are marginal at best. I have had great results from installing progressive suspension springs and moving up to a heavier fork oil (20wt ) to keep the bike from diving so far during braking.

www.progressivesuspension.com

You should look at having the forks rebuilt with these parts and you will find that the bike handles much better than before.
The springs that are in the bike are old now and should be updated with new style parts.

Thanks and I hope that this helps.

Blow-by of the left front fork 'seal' (Honda M/C 1981 cm400c)\r\nI also own 1980 (same) but it doesn't have the 'air' added on top like this '81. . . 1) question: ` Could I just drain the fork oil...


Probably the reason the fork seal is blown is too much air pressure. Definitely fix the seal and put in the correct amount of oil. You do not have to put air in to the front forks if you do not want to. To properly set up your suspension, set your rear shocks first, hard for two, soft for one, etc. Now load the bike, you or you and the passenger. With the front forks set to near max pressure (only 12 to 14 pounds air pressure do not go over max recommended pressure) bounce on the motorcycle seat and bleed off the pressure in the front forks till the front and back of the bike drop together. This is the correct way to set up your suspension. A bicycle foot pump with a pressure gauge works best works best. You will be near max pressure in one small hand squeeze of the foot pump. You will find it only takes 7-8 pounds of pressure to set up your bike. Just remember, You do not have to put air pressure in to your front forks, they will work just fine. You just wont benefit from the adjustable design.

How do u fill the down tubes on a hoda shadow


First of all do not add oil to your front forks with out draining them first. If you over fill your forks with oil you will damage your forks. To change your oil in your forks, first center stand the bike and lift the front wheel by putting a jack under the motor. Remove the front wheel and axle and put a pie tin under the fork tube. Reach up into the bottom of the fork tube with a hex key and loosen the screw but do not remove. Now take the air pressure cross over tube off, this will allow you to unscrew the fork tops( On some bikes you may have to put a towel on the tank and unbolt the handle bars to get them out of the way.). Pull the screws out of the bottom of the forks and gently pull down the oil should come out now. If you need new fork seals take the lower tubes off and replace(You may need to take off the fender and hang the calipers with wires.). Turn the lowers over and dump out the oil and reinstall fork lowers. Snug up screws and sealing washers on the bottom of forks you can not tighten till you put on fork tops. Now pour in measured amount of oil, again do not over fill. Put on fork tops and air crossover tube. Now tighten screws on bottom of fork. Finish reassembling bike.

How do Fill Front Forks?


YOU FILL FORKS BY TAKING THE CAPS OFF AT THE TOP BY UN DOING WITH A SPANNER BUT YOU MUST DO THIS WHILE THE FRONT IS OF THE GROUND AND THERE IS NO WEIGHT PUSHING THE FORKS AND YOU NEED THE MANUAL TO SEE HOW MUCH FLUID GOES INTO THE FORKS EXAMPLE IT WILL SAY (13CM FROM TOP) THIS MEANS FROM THE TOP OFF THE FORK YOU MEASURE 13CM FROM TOP TILL THE OIL HITS THE 13CM GOOD LUCK

How to fill the front suspension on a ktm exc 2001


If you get the sevice manual or contact a dealer to get the correct oil amount for your bike, they need to know the model and year, you have to have the forks off the bike. take the fork caps off, take the springs out compress the upper fork tube all the way and add the specified oil. if they also give you the measured amount from the top that's the best way to get both fork oil levels exact. there is a special tool that you set the oil level in millimeters and it sucks out the oil to the right level, but before you do that step after adding the oil always pull and push on the cartage rod several times to remove air from the cartage tube. you will hear the air coming out and you will feel the changes in the cartage rod as the cartage tube fills up with oil and the air is removed.
something i'm confussed on though is if you replaced a seal you would have had to brake down the fork to replace it. you would have poored the oil into a container, cleaned all the internal parts,and used a fork seal driver to install the new seal. part of your question asks where do i put the oil in? thats in the open end of the fork after you have taken off the fork cap. It sounds to me like you only replaced the dust seal on one fork. that is not going to fix your leaking fork. you need to replace the oil seal thats pressed inside of the top fork tube.
