I broke the little 5mm bleeder screw that's on the clutch master cylinder. Tried to remove the broken screw using a grabit tool, but no luck and now it looks worse than before. There is enough screw left in the hole so that it's not leaking oil. Question is drill out the remaining, or just leave it? Is there anyway to re-thread the hole afterwards? I notice what looks like a small sleeve in the hole, can that be replaced? I couldn't find a sleeve to replace it with on any of the ktm parts stores.

id say its a good excuse to buy an aftermarket slave cylinder, its going to fail at some point anyway.
just sayin...
