    Need clutch help Cr80

    1997 Honda Cr80 Expert

    I just put back together the little brothers Cr80 after rebuilding the bottom end and am having some trouble with the clutch.

    With the cable in the same adjustment as it was before the engine was removed it will not release(motor dies when put into gear at idle). I tried adjusting the cable and no matter what i have done it still does not release, I even adjusted it out far enough that the clutch slipped while riding it(only rode it for 10 feet). Also with the cable at either adjustment the pull on the clutch lever is WAY to hard, It was an easy pull before removal. Easily twice as hard to pull the lever on this bike than on my ktm 550(2 stroke) which uses ALOT heavier springs.

    With the inner nut on the clutch hub but the spring plate/springs not installed i can move the inner hub back and forth easily.

    If someone has a manaul for the bike and can explain or post the clutch install info for me that would be great.

    Thanks!

    i would try switching to a lighter weight gear oil. Unless you think somethings out of place.

    The problem was that the piece that the lever pushes on which then pushes on the clutch hub to release pressure off of the clutch would not move.

    I figured out the problem tonight, Well figured out part of it. I had a extra washer behind the nut in the middle of the clutch hub so the piece that released pressure could not move back. Now i dont know where the washer was supposed to go!

    Theres a Thrust washer that goes under the outer clutch center. If need be I can scan some of the manual, its for the older CR80, but the motor hasn't changed much.

    If you could do that I would really appreciate it!
