Changing the fork oil
OK, I have the bike apart for repair, and thought I would try and change the fork oil, since it is at the service point for it. Our friend Toni Tuusinii in Finland offered this picture. wtf is this all about? Can anyone offer a quick explanation ??
In his words, he says to use tie-downs to compress the spring, use one of the ties to hold the tie-down in the collar, and secure it with the bolts. Will all of this be obvious when I start the teardown?
I have seen some writeups on this here invention before, but this is the only one I can now find. If you have changed your fork oil before, then I bet this is pretty obvious. How about it, doods?

Hello!
It's good to be able to help... But anyway it isn't so confusing when You have the parts at Your hand, but when You get the tie-down get one without hooks. Get tie-downs with only loop so You can place it between the collar and the tighter and around the bolts. This picture explains little more:
The bolts go the holes in the collar and are there only to secure the tie-down. The force acts to the tighter(sorry don't know what it is called in English) not the bolts and in fact last time when I did mine I even didn't use the bolts because they are a little disturbing. I've also drawn another picture that explains the principle and it can be found here:
 Hope this helps...

Thanks Toni. One more question. The first picture shows what looks like two (2) tie-down being used. I understand that one strap is used to go from one bolt, thru the axle opening down below, and then up to the other bolt . That is tightened to pull the collar low enough to loosen the top nut.
But it looks like a second tie is also used, . Is this just a backup? Your drawing shows a 'hose clamp' that is used to hold the collar down? Does the second tie just loop around the top of the collar, and get pinched into place with a hose clamp so it wont come off?
Maybe that is why you dont use the 'bolts' anymore? Thanks!

No. Its the same strap that first goes between the hose clamp and collar
and then over the bolt to secure it. Then it is routed down and trough the
hole for front axle. Then up the other side and also between the hose
clamp and the collar and then over the bolt to secure it. In the picture
You can see how is it done. The left one shows better that first it goes
form the top to between the hose clamp and the collar but what You can't
see in the picture is that the loop of the strap goes still over the bolt
as the right one also shows. And if You look carefully You can see that the
right one is also routed the same way - first from the top and then the loop
over the bolt. In this picture
 You can see how the tie-down is routed trough the front axle hole. The reason I don't use
bolts anymore is that the hose clamp holds the tie-down very tight , but
then it is important that You route the strap form up to down. And the
reason why bolts are a little disturbing is that the nut inside the collar
is quite low and You want to compress the spring as much as possible. And
now that Im thinking more if You don't use bolts in the holes in the
collar You could use some smaller bolts (or something equivalent) to make
sure that the tiedown cant go trough the collar and the hose clamp.

Been there, done that. These forks are a real pain in the ass to work with.

No kiddin'!! But thanks to Toni and his great pictures and illustration, it worked!
THere was more than one time that I wanted to stand up and just take the whole mess to the dealer and let him put it back together. Well the first one was a bitch, since I wasnt sure what was going to happen. But the second one took half the time, and went way smoother.
But damn! Why couldn't they just put a drain plug down at the bottom? a real p.i.t.a.

Good for You that You got it back together... And first one is always trickier - but in time You're goingto use to it and it comes easier. And I'm also wondered why no drain plug? It would make this 15 minute job...
