so I'm blasting from Austin to San Antonio, and I'm taking the 410 around San Antonio, fighting traffic, doing lots of shifting. and I notice my clutch cable seems to be getting longer, and longer. And I'm not really in a position to do much about it, because I'm trying not to get smeared by rush hour traffic on the 410. Entirely too soon for my liking, I suddenly have failure on my clutch lever. I cannot disengage the clutch at all. I'm not happy, but I can bangshift the last 20 miles. Yes, I winced with -every- shift, doing it as tenderly as I could, feeling like a horrible person. However, I was kinda stuck with the situation. And if I stopped, I'd -be- stopped, with no-one to come pick me (or my bike) up and take us home.
So I'm coming onto my final turn, and I need to slow down even more. I make one final bang-shift, and there's this jar, and a horrible grinding and banging noise, sounding like I've completely smashed my trans.
I'm also, blessedly, free-rolling, instead of my rear wheel locking up.
The end result was a bit odd..
Apparently the adjuster screw on the clutch arm had managed to un-screw itself rather neatly... And the horrible noise? yeah, that was the end of my drive shaft uncoupling itself. Apparently someone, a long time ago, didn't put it back together right, and cross threaded the nut holding the final-drive end of the nut on, and stripped the threads out, hard. The end result eventually un-threaded itself, and broke free when a hard enough bang-shift was applied.
