The reason for the COMPLETE teardown is to look at the parts to see what shape they are in, to clean them and to make sure they are in good working order.
Seals can be changed w/o having to tear down the forks.
A small round or flat punch will work. You can also use a small seal puller once you get a small hole in the top of the seal.
I use a small punch and hammer. You have to be absolutely careful not to damage the lower forks. I lightly tap the punch through the top of the seal, and carefully pry it upwards.
I use a piece of plastic PVC pipe the drive the seals back into the forks. I cut a piece longer than the forks to clear the top, then put a 2X4 over it, the lightly tap the seal into place.
A vice is a godsend for working on forks. But with some patience and time, you can do it on a garage floor.

See my latest writeup on this subject w/pics...new thread...
And Im not condoning this for all, but if circumstances permit, its definitelty easier....my fork oil was normal when drained with just a lil black ooze (seal ?)...no water or discolloration, so I did the quickie.... ...quicker to be back riding....*wink*...

Sorry I missed your first post.
I think the oil was in OK shape when I drained mine. I've had it turn white on other bikes due to water getting it there. But the VN was pretty good looking inside.
I actually agree with In'till'zah, a complete diss-assembly is not necessary. But I have no idea what this bike has been through before I acquired it, and I like to be thorough.
I've actually used the screw method on a set of older dirtbike forks. It works well.
I think this bike of mine had been sitting for the past 20 years, so the diss-assembly method allowed me to clean all the parts very well. It's also kind of neat to see how everything works.

This is my first motorcycle so I have little to no previous experience to judge by, but I don`t recall any particular problem with the forks or suspension when I last rode it in 2008. The fork tubes were twisted 30* or so in the head clamps in my accident, but were easily twisted back straight by hand after loosening the clamp bolts. The bike was ridden 5 miles home from the accident scene by a friend, with the off kilter fork/handlebars, but has not been ridden since the fork was straightened out.
My feeling are that I should do a complete dis assembly and inspection as per lance`s directions, as much because the age of the scoot, as for any damage it may have received in the accident.
I am curious which method you would recommend for my bike based on the information I have related here.

Thanks...thats about what I figured...old seal is trash anyway, so do what ya need to get it out (Im gonna use woodscrews and a dent puller)...
If it came to it, I'da removed the bottom hex, then manually "topped em out"...thats how we always did it...
Doing it tomorrow, so will post my results after...

4: Removed the dust seal
5: I got some small sheet metal screws and screwed them into the old seal, after I removed the retaining ring. I used 3 of them and put them at 1/3 of a turn from each other (2,6,and 10 o'clock) I just put the screws about 2 threads into the seal, not any more than that. The trick is to get screws that are small enough to clear the main fork as you pull them up, but have a big enough head to grab on to.
6 GENTLY work the old seal up off of the fork, I just would pull a little bit on each screw, take you time. It may take a couple of minutes.
7. After you get the old seal off, I just used a bit of new fork oil on the inside of the seal and on the fork to install the new seal. It should slide right down with very little resistance.. To seat the seal, I used a punch and tapped it into the recess where it goes. TAP GENTLY!!!!
The rest of the process is just a reverse of this. I used hydraulic jack oil for my fork oil. Seems to be working well, I'll know more this winter when I service the forks and see how it held up.
This was done on a 454 LTD, but the process will be the same as the Vulcan...

Releasing air, draining fluid, removing lower hex should be enough, no ?

Nice vid, it still amazes me that people still think it's necessary to do a complete tear down of the forks to change the oil seal and dust cap...
But to each his own....
