so i was riding my 919 to the office this morning, doing about 85 in 6th on the freeway, approaching my exit i moved over to the right and prepared to slow down... i tried to grab the clutch for my first downshift, and it wasn't there.
the clutch lever was still attached, but it was just flapping back and forth - no cable tension at all.
i got slowed down somewhat, got over to the shoulder, slowed down to where the engine was choking from lack of speed, and then cut the engine and rolled to a very noisy stop (engine rotating, chain thwacking, rear wheel jerking).
at first, i thought something in the clutch broke, and i was about to call aaa, but after i calmed down a bit i looked at the bike more carefully and saw that the clutch cable adjuster (at the engine) was completely unthreaded. i was able to hand-thread it back in just enough to ride the rest of the way to work, and i'm about to go down to the garage with some tools to get it adjusted correctly and tightened down.
i was the last person to work on my clutch cable, so i have nobody to blame but myself. but i'm shocked at how quickly it came loose. the clutch adjustment hasn't moved at all in the last 4 months (since i got my bike back together), but between shifting into 6th when i entered the freeway and my exit (about 5 miles) it came completely loose (i'm guessing about 30 turns of the thread nut).
in hindsight i think i reacted to the problem correctly. i could have tried clutchless downshifting as i slowed down, but that would have left me with more wheel torque that i couldn't disengage - it was probably better to try to stop in 6th than a lower gear. i didn't panic, and i got out of traffic quickly.
was there a better way out of the situation?
and i think this weekend would be a good time to go over all the nuts and bolts to make sure everything is torqued down correctly
