I just had Nick of Valley Ducati Service (Speeddog here on the DMF) pick up my 748 forks for a re-spring, fluid change and new seals.  He has a set of used 0.85 springs that are straight-rate.  Should be good IMO.

forks arrived today :D :D
they look GREAT. better than i expected.
the lowers are in great shape, tubes actually look scratch free, just some black spraypaint to be removed.
the sliders are nice and shiny, i took a microfiber to them to remove some grime, there are no signs of pitting, just some dirt where the lowers attach.
seals look leak free, although i may have them replaced just so i don't have to do it later...
springs feel REAL stiff :D
red anodized caps are slightly faded to a bit of an orange... which should match my tangerine bike just fine ;D ;D

i am PUMPED.
anything else i should check for?

Maybe a fluid change?

I got mine the other day and took them apart....oil definitely needed a change. 

I'm going the full rebuild.  New springs, Racetech valves, etc.

yea, i will definitely be changing oil when i do the springs, but not so much revalving... per recommendations...
i'm looking if there is anything physically wrong with the fork structures, any particular defects to examine for aside from what i mentioned...

Use your triples as clamps to begin disassembly.  Do NOT use a vise.  (I suppose you already knew that or someone already posted that.)

I just bought some MR Clip ons , tried the dp ones but it wouldn't fit with the triple

@corey, .90 springs would be about right.

Might as well change the oil while you've got 'em apart.

well.. i was planning on respringing the forks OFF the bike, so i could go in, swap triples, install forks, and be done...
i was going to be using these: http://traxxionstore.com/detail-10.aspx
along with my vice and some foam rubber between... should i not?
can i do it with NEW triple clamps OFF  the bike?

I did mine on my bench with a vise.

I use these .... Craftsman Vise Jaws

Worked perfectly.  They are a rubber/poly type ... magnets keep them on the vise.  I get alot of use out of these things.  You don't have to tighten all that much... they grip well.

Love me some Craftsman too...

Alright, so I guess the next part, which I haven't looked into very much (I am assuming it's easy enough) is swapping triple clamps...
What's all involved? I know i need the special tool, no big deal, but what else is going to go on? I am planning on upgrading to speedymoto tapered  bearings while in there...

I just did this on my 1999. Not hard.

Get gauges, bars, headlight, etc, out of the way.

Loosen three pinch bolts (your stock triple may have more, like two per fork tube) for top triple. Remove center nut. Whack with rubber mallet.

Top triple comes off. A nut is revealed below this. I used a spanner wrench to loosen it (didn't take much effort) and then removed it with my fingers. There's a big washer below that, it can come out too. Now the lower triple can be removed.

You'll find this a lot easier if you suspend the bike from the sealing. If you are using any kind of front stand, you'll get to the point where you would remove the lower triple and discover you can't because of the front stand.

i'll be lifting from below with wood and jackstands...
what about the bottom triple, replacing that sucker.. how do i get the steering tube and bearings and everything in there?
pretty simple?
what i'm concerned about is that the triples i'm looking at have a much larger bottom triple... (IMA)
i know that for the forks, i need to match the measurement from the bottom of the fork tube to the bottom of the top triple, correct? how do i go about that if my triples are a different thickness....

The IMA triples come with the steering stem.

You'll measaure to the top of the lower triple. That will stay the same when you change triples because the triples are flat across the top. The extension is southbound on thicker triples.

If you order a set of bearings from SpeedyMoto (they'll send you SKF) it will include the washer that goes below the lower tapered bearing on the steering stem and the cover washer that goes just below the adjustment nut on the stem (above the top bearing set).

The races will be pressed in to the stem. You knock the old ones out and drive the new ones in. Freeze 'em and they drop in even easier, but this is not difficult it turns out.


Note, that when I say it comes included in the speedymoto kit, I can only speak from experience for the older Monsters (pre 02, and all SS's, and 851/888 bikes) because they came with a tapered bearing set from the factory.
