I just went through a $100 lesson I thought I'd pass on in the hopes of helping some other KTM owner the mistake.

I was back-bleeding my clutch system last night, and went to button everything back up. I put the bleeder valve back on, replacing the fitting for the Magura kit, and tightened it up. The oil kept coming out the bleed hole - ugh! Several tries later, I realized I was hosed. I went to bed, resisting the temptation to re-model my bike with a hammer.

I pulled off the slave cylinder with cooler temperment (and a new slave cylinder ready). I found that the Magura bleeder fitting had a damaged thread, which caused ALL of the threads in the cylinder to get buggered up. Now when I put this on, it seemed really easy, so what gives? Anyway, I cleaned it up with an M8x1.0 die and put the new cylinder back on.

Moral of the story is be really careful with threading the back-bleed kit fitting onto the clutch slave cylinder!

I use a syringe and a piece of 6mm tubing. I force it on the existing bleeder fitting, never taking it out. I turn hose and bleeder screw together to close.

You probably know this but if you use the syringe (which I do) be sure to first bleed a little fluid off in the normal way. This will force any dirt out of the bleeder valve instead of up into the system.

Cheap as fluid is, pumping it all out is probably the ticket.
