    Hello guys.

    I changed the oil and oil filter today. Used A9 Racing semi-synthetic motorcycle oil 10w-40.

    After the change the clutch lever was suddenly super tight. I tried to adjust both on the lever itself and the mechanical adjust near the clutch itself to no good.
    Can this be caused by the oil?
    It's like the clutch is always engaged now. There is a big slack on the clutch lever(can't get it to grip because the wire is already pulled out it seems). When I start in neutral, and change to ex. 1st or 2nd gear (without touching the lever) I can still push the backbrake and the tire will stop, but the bike will still run, even in 2nd gear(as the clutch is engaged all the time).
    Anyone know what the cause might be?

    Cheers

    when the bike is parked and your not touching anything, the clutch is engaged. the motor is connected to the wheel.
    when you pull the lever to stop the bike, the clutch is dis engaged.
    when the motor is running and it's not moving, never force it into gear. your transmission hates that.
    unhook the cable at the engine and try to push the bike, engine not running

    I did that, and the arm on top of the clutch now snapped back to the position where it should be. The back tire now locked when in gear. It seems like the wire itself is stuck inside the "isolation". Cant pull it the tiniest to either of the ends.

    Oil change would not cause that problem. "Big slack on clutch lever" would seem to indicate a broken clutch cable. Are you saying that on the center stand you can not move the clutch lever on the engine and get it to change gears or to neutral?

    Time to take a look at the cable from end to end. There is something going on. I would guess it was a wear mark and that it got water in it and maybe some rust got going or worse. If you have "Big slack" now and nothing is working I would guess it broke. You just might want to take it off the bike and have a really good look and inspect how it is working. Overall condition of the cable to see if it is disfigured or out of form in any areas.

    if bike is on center stand bike in neutral tire will spin
    there should be 3mm play at clutch lever.

    sounds like you need a new clutch cable if wire will not move back and forth when disconnected from lever and motor

    Okey, thanks guys. Tried to lube the cable with WD-40 overnight to see if that solves the problem.
    If not, do you guys know if a clutchwire from a ‘81 650 will fit my ‘81 750?

    i was given a .22 rifle because the guy oiled it up with WD40, put it in a case, a year later he almost shot his wife. because the firing pin was so gummed up it stuck out and fired when the bolt was closed. he was ordered to get rid of it. it was really hard to clean up

    you can lube cable with a plastic bag poke cable through cable make tight and add some oil into bag let soak over night.
    it sounds as if your cable is past lubing
