Can't get clutch adjusted right...

Now that my electrical woes have been solved, I am able to ride the bike. When I bought it, the clutch engaged at the end of the lever's travel, and would have a harsh engagement from a stop when the bike was warmed up.

I went through the clutch adjustment procedure, and wen't for a ride. I warmed the bike up properly, and did about 5 minutes of slow 25mph roads. Once I got out on the open road, I let 'er rip. I went about 50mph for no longer than 1.5-2 minutes. I slowed down for a turn, and heard a screeching sound, then the bike died. I was able to get it started back up and get it back home. The willingness to idle seems to be corrolated to adjustment of the clutch, as I sat and tried to go through the procedure 3-4 more times.

I'm not sure what I'm doing wrong, but the procedure seems to only address teh 14mm lock nut, and 12mm adjuster. If you pull back the sheath, there's also a 10mm hex. I'm not sure if I need to do something with this...

Anyways, you guys were really helpful in diagnosing my electrical problems, so I figured I'd ask about the clutch. I read the newbie FAQ, and did a search, but didn't find anything.

Thanks in advance,
