Hi,

the general procedure is described in the 907ie workshop manual or the Marzocchi M1R manual that can be found in the downloads.
Hints I can give are:
- if you use a flat screwdriver to pry out the dustseal from the slider tube never do it from the outside. The wall of the slider tube is thin and can break
- dito for the oil seal. Use a heat gun and heat up the outer side of the slider tube (Don`t hold it too close or you might burn the paint). Heat just enough so the seal will come out easily. If you use a screwdriver to pry it out be careful and put something under the screwdriver to protect the edge of the slider tube. The pressure of a screwdriver used to pull out the seal can damage the sidewall.
- When reassembling wet the oil seal with some fork oil and slide it on the stanchion tube. Push the stanchion tube in the slider and then use a proper tool to push in the seal. If you put the seal in the slider first it will be more difficult to insert the stanchion tube and chances are higher you may damage the oil seal.
- fork oil: use 5 or 7.5W
- the air gap (oil level from the stanchion tubes upper edge) should be 160mm. Bike shops sell proper siringes. These are connected to a tube that can regulated in length. Set it to 160mm and suck out the oil until none is sucked in anymore - done.

When ASR Performance went to rebuild my forks, he spoke to a company in Sydney as well that does this mod, it involves drilling a 6mm hole in each leg that allows the oil to return faster thereby reducing stiction, which he said is a major problem with these forks.

He also put 5w oil in compression leg and 10w in rebound leg, oil height I think was 165mm, plus heavier springs to suit my weight [std was ".75" now ".95" [I think!!], I am 80kg, and new bushes from BMW.

It was a mod that Ducati did to later bikes

the above was pasted from another post of mine,
Also check your bushes as I have had two sets with stuffed bushes.
I had a bit of a ride on the new forks and they are far more supple, a nice feeling of control. At low speeds, 30 40kmh they feel supple but a bit knobbly, but get up to 70-80kmh they really smooth out nicely.
