For now I ordered a new MS and will look into this further when I have time, for right now I jsut want to ride. I contacted some one else in northern Ca. He asked for some pics before sending it to him, but I have to wait for the old to get back to me before doing this.

No pics sorry, anyways the brass sleeve has about 3mm thick wall (internal diameter just a little over the piston diameter).
No need to reach the bottom of the MC with the new sleeve, 4-5 mm from the bottom is ok, that's the space where only the piston spring goes, so even if the sleeve isnt perfectly aligned with the old hole is not a big deal.

Did you have to make a hole at the side

just where the liquid store feeds new liquid into the system? What dia hole did you drill to fit the sleeve in? Where did you find such a smooth pipe?

Right! i've forgot about that :)
The brass sleeve was obviously machined by my friend, dont know exactly the external diameter of the sleeve, but roughly it was 15mm, i would say "the thinner, the better" (so u dont need to drill out a lot of your m/c) as long as its strong enough to be slightly (almost nothing) pressed in, we used some loctite to avoid any leak.

I drilled the hole (actually 2) for the reservoir, the big one is 2mm IIRC, the tiny one is about 0.5mm and its in front of the other hole, under the little metal screen (this is the self-purge hole), i've used a .7mm because it was the thinnest available. After drilling i've smoothed the inside of the sleeve with some fine sandpaper (just where the holes are).
Holes drilled AFTER installing the sleeve, of course.

SD's master cylinder installed. I had to buy an adapter for the tube to be able to fit as it has smaller diameter but nothing else. Just installed it, bleed it and ready to go. It's somehow stiffer than the original but not that much that it can be a problem even when I drive downtown during rush hour.

Cheers.

I used the 10.5 Magura on mine. The rebuild kits didn't work for me.

What is the benifit of the 9 Magura vs the 10.5? I thought you wanted to have the 10.5 size on the ADV bikes?

About a 40-50% reduction in lever pull. It is only good, no downside. Why anyone goes stiffer is a mystery to me.

I did it as a performance mod, my OEM masters were fine and I sold them as used parts. All my KTMs and Huskys with Magura masters got a 9.0, including 3 950s. Never a problem with any of them, worth doing even when you don't "need" it.

why 2 holes?
, under the little metal screen (this is the self-purge hole)
what do you mean self purge hole?
, i've used a .7mm because it was the thinnest available. After drilling i've smoothed the inside of the sleeve with some fine sandpaper (just where the holes are)
sand paper inside a 10.5mm hole?
Holes drilled AFTER installing the sleeve, of course.
the inside of the sleeve was made on a lathe?

great mod I should say. Cheers

Thanks. I will have to remember that for the future.

what do you mean self purge hole?

the small one (if u sit on the bike and look into the reservoir, its about 3mm on the right of the main hole) lets the air escape (if there is some) when u start to pull the lever but the piston will pass it soon, so it doesnt affect the clutch operation

, i've used a .7mm because it was the thinnest available. After drilling i've smoothed the inside of the sleeve with some fine sandpaper (just where the holes are)
sand paper inside a 10.5mm hole?
a little piece of fine sandpaper on the tip of a screwdriver, just to smooth out a little where the holes are

Holes drilled AFTER installing the sleeve, of course.

the inside of the sleeve was made on a lathe?
yep

I like to workout while I ride....Seriously, the SD master (which is ridiculously expensive and worth having only as a used part) isn't that much stiffer than the stocker. I'd say about 15-20% and that's without the Oberon slave installed that's supposed to lighten the pull.

exactly, is not that bad just a little stiffer but not a real issue while driving. The whole setup cost me under $200 so I was the way to go for me.

A one finger clutch pull is worth its weight in gold.

Still not getting this as it offers nothing in the way of an upgrade. All negatives only.

Going the re-sleeving route

Experiencing a weeping master cylinder as well. 2006 950 Adv, 17K miles

Have called a few bicycle stores that are Magura dealers and they can order the OEM Magura MC for $280 CDN.

Decided I'll go the re-sleeving route and found this place in New York which I'll ship the part off to.

Apple Hydraulics
http://applehydraulics.com

They will re-sleeve with brass for $90, adding shipping both ways I'm probably up to $130ish in the end. Worth a try if it cures it.

Hope this helps someone

That and a sicass racing light switch gives you more bar room so you can cut them down AND a "off" headlight switch AND less lever effort.
