Hey guys, the '87 YZ80's clutch does not want to disengage. It worked fine all last year, then the last time I rode it, I kept having to adjust the cable tighter and tighter to pull it far enough to disengage the clutch. Then I loaned it to my friend and now it doesnt work at all. I put on a brand new lever and perch and cable and still no matter how tight I adjust the cable, it will not disengage the clutch. The motor runs and I rode it without the clutch the other day. I even took the cable off the clutch arm on the engine and turned the arm with a wrench and it does not disengage, so its not the cable or lever. I have been using the same tranny oil in it as I use in the 250R, Honda synthetic gear oil 80/85 for CR engines in the red bottle. I change the oil in it very frequently, after every other ride. Every time I change it, I dont notice anything unusual in the old oil, like metal debris. It always looks good. Could using this oil have something to do with it, llike causing the plates to stick to eachother, or do u think there is a problem with maybe the clutch actuator arm/cam thing inside the engine or something along those lines? The clutch did not slip or chatter before this happened.
