The clutch cable is binding on my 86' CR80. When I pull the hand lever and let go, it doesn't retract. I can use a wrench on the crankcase clutch level to pull that cable back down "to rest." I can push it forward into that cable slack too. The cable basically isn't sliding free. I can't find anything pinching it anywhere but I would like to detach it from the bike first to see what's up before I order a new one. The perch side was easy, but I don't now how to get it off the engine side.
