Hi MD
Thanks for the tip! This is the kind of advice I'm looking for! Did yours free up? What did you have to do? Did you just pull on the clutch lever a bunch of times?
In researching clutch problems, that seems to be the most common thing that goes wrong in bikes that haven't run for a long time.
What worries me is just the way that this problem suddenly occurred. I got about about 5 good feeling clutches, then 3 or so "mushy" feeling clutches where the friction point was kind of vague, then 1 chattery, grabby clutch, and then it felt like the cable snapped suddenly. I checked the cable and it was still intact. I removed the outer clutch cover and the lifter arm that the cable pulls on was popped out of place a little bit. I pushed on it with my finger and it popped back into place.
I tried to do an adjustment on the lifter arm but no change. now the clutch lever has resistance like it is compressing the springs, but it doesn't disengage.
I keep thinking something must have broke, but I don't want to take it apart until I get a couple of second opinions, or know what to look for when I'm in there.
