Holding in clutch, starts creeping forward

Look on the underside to see if the size is stamped.

It is on the coffin models.

here's what I found:

That adds to my confusion...

I'd say 13 mm, but I'm guessing.

Yoyodyne has some pics and listings of kits...with a disclaimer... http://www.yoyodyneti.com/Category.aspx?CategoryID=3016

Give them a call, or use the info to correlate with what you have.

[Speeddog]

That's a 12mm master.

[ducpainter]

That's a 12mm master.

Listen to him...

I don't think he's guessing.

[Privateer]

That's a 12mm master.

thanks Nick.  Do you have a recommendation on where to buy the rebuild kit? 

[Speeddog]

I'd try Yoyodyne first.

Also possible to get it from a KTM dealer, AFAIK.

[Privateer]

apparently I'm hosed.  Yoyodyne says the masters I have are not rebuildable.

just effing great.

Check with KTM.

If  that doesn't get you anywhere, give me a call.
I've got a goldline master that's in need of a rebuild as well.

[Privateer]

thanks.

I dug out my old coffin master to see if I could get that to work so I can at least get back on the road.  Got it hooked up and plumbed, just need to bleed it out real good and see if I can get it adjusted right.

When I was trying to pump fluid down the line when I'd squeeze the lever it would shoot a fountain of fluid out if I let the lever go too quick.  I don't remember that happening before.  normal?

[Ddan]

Normal, that's the return to let fluid back into the reservoir.

[Privateer]

thanks.

I guess I don't remember it being forceful enough to hit me in the face.

Now if I could just get the clutch to fully disengage when I pull the lever...

[Privateer]

i give up.

[Privateer]

alright.

some progress.  Apparently I just needed to take the weekend off.

I swapped in my coffin res master and OEM slave cylinder and it seems to run OK, just around the block.  I need a proper shake down to  ensure the clutch is engaging fully, I suppose.

I wonder if the coffin m/c has enough 'power' to push the oberon piston.


I have a call into the local KTM dealer to see if they have rebuild kits.  If they don't reply to my email in the next couple days I'm going to stop by on the way home from work and ask why they're ignoring me.

[Privateer]

stopped by the local KTM dealer today and explained the situation.  kid at the parts counter found the only 13mm rebuild kit they had and the piston looked NOTHING like the one out of my m/c.  At $36 I wasn't comfortable buying it and experimenting.

I'm starting to get the feeling I'm ass out and will just have to buy a new master cylinder.

poking around on ebay I found this:


http://www.ebay.com/itm/NEW-KTM-BREMBO-FRONT-MASTER-CYLINDER-REBUILD-KIT-125-540-CC-2001-04-50313008300-/230841443470?pt=Motorcycles_Parts_Accessories&hash=item35bf38e48e&vxp=mtr

that piston looks the same as mine, and the 'big' spring too' but the wrong size.
