The seal under the dirt seal on the fork was leaking when I picked the bike up from the owner. left the fork oil under the dirt seal kept bouncing the forks up and down for 4 days the seal got soft from the fork oil so I pulled the dirt seal up then cleaned the fork oil under it with a rag then checked it for leaks then pushed dirt seal back down in the groove and its not leaking now 200 miles and still dry.

Before you take it to the shop try this.Get some camera film,Cut the notched edge of it and trim the top to an angle of 45 deg..Slide this up into the fork seal and working it up and down,slide it all the way around the seal.When you get the feel of it,you can feel tiny bits of grit.This will clean the grit out 99% of the time.I always keep a piece of film in the toolbox.

On the top and bottom parts of the triple tree either both or one will have bolts. First take the fender off. Take the front tire off. Loosen the bolts on the triple tree. They should slide down. If not you have to get a rubber mallet and tap on the top of the fork and twist the fork as you are doing this. Once it is out, pull the dust seal off the top of the lower fork. There will be a clip inside, take the clip off drain the oil out of the top or bottom depending on how the forks are made. Push the fork tube down into the lower fork slightly, pull both apart with a firm tug and they should separate.

Testimonial: "Very helpful thanks alot"
There is a seal in the "slider" of the front fork, the part that moves up and down. I haven't had a chance to work on the later forks but the earlier 41mm forks are quite simple.
Start by taking the drain plug out of the bottom of the slider and work the slider up and down to blow out all the oil. Then, remove the front wheel. Remove the top cap from the upper tube and loosen the top plug. Now, with the top plug loose, loosen the pinch bolts and slide the fork out of the triple trees. Remove the top plug carefully, There is a BIG spring in there. Once you have the plug out lift the spring out and set it asside. Notice the tapered end of the spring. It goes back in first. Turn fork tube upside down and allow as much oil to drain out as possible.
Now, look at the bottom of the slider where the axle goes. Up in a hole there is an allen head bolt. it is designed to use a special wrench but a regular 8mm allen key in GOOD shape will take the bolt out. It's best to use an air wrench to do this with. With the bolt out, the slider should slide right off.
Down inside the top part of the slider is where the seal is. Theres a snap ring, a spacer, and a seal. Replace the seal and put a little oil on it to assist reassembly. Put everything thing back together and add the appropiate about of oil. Since your forks are much larger than mine, I have no specs as to the quantity. The owners manual should tell you or a call to a local Harley dealer. Sorry but thats a good as I can do. There is a "wet" measurement and a "dry" measurement. Since you disassembled your fork, use the "dry" quantity of oil
