    Guys, I'm at the end of my rope changing my clutch. I've followed several articles here and videos on youtube, but I just can't seem to get my clutch to work properly.

    What I know:
    I can see the plates move when I pull the clutch. - see video
    I can't move the lever by hand. Only with the clutch handle.
    I tightened the 5 screws/springs as close to some pictures I found. I read it's supposed to be 7.2ftlbs which means it shouldn't be super tight.


    I've used my haynes manual and the links found inside the .txt

    I wasn't able to submit my post with the links embedded but I put them in a text file and uploaded them. They have a video of my clutch in action which I think is key to y'all understanding what I did wrong

    I'm just looking for any guidance on what to try next.

    when bike is on center stand bike in gear clutch pulled in rear tire will spin due to the oil in between the clutch plates. this is nornal

    you also need to soak clutch plates in oil overnight before installing them not stright out of the package as shown in your vid link

    Actually, it doesn't spin at all. Say I have it in 1st gear, if I pull in the clutch it still doesn't let the tire spin. The tire never spins freely.

    what you are saying is with clutch pulled in you can not spin the tire by hand?

    Yes, I pull in the clutch, spin the tire and it stops as if its in gear.

    I know this will not fix the problem but the spring on the arm where the cable attached is not in the proper place.

    if the plates didn't separate like they should when you pull the lever, you couldn't move the wheel with your hand.
    go for a ride and see if it works

    It won't spin free like a bicycle wheel; you have to keep moving it.
    Try this:
    Turn the wheel with the clutch engaged (lever out), then with the clutch disengaged (lever to the bar). Is the result same = same, or different?

    It won't fix the current problem, but correcting that will prevent a future problem. Good catch.

    And that ^^^ makes me wonder if the gear on the throwout arm is in correct contact with the gear sector on the throwout plunger. That would account for the wheel acting like the clutch never disengages.

    Almost looks like the lever on top of the catch is too far forward....

    Edit: I typed that yesterday, but never hit the send button.....DOH. Anyway, I agree with k-moe......try removing the c-clip, pull the arm off and index it back a couple teeth and see what happens.

    There are aligning marks on case and lever. You may have to remove clip to see its location.

    So compare your lever to the pics from Toomanybikes.......

    See how 'far forward' yours is? You're not getting the clutch to disengage. Put yours back a couple teeth and see how it feels. You may need to go ack more to get the preload. Then you'll dial it in the rest of the way with the adjustments at the end of the cable, as well as on the left hand lever.

    I'm not seeing anything wrong with the spring, though.....

    The hooked end that engages the arm is just sitting under the arm, instead of the arm being inside of the hook.

    Strange.… Maybe I don't have the right picture. But on my screens I don't see either ends of the springs at all. Oh well

    I know I'm a little late to the party but another indicator to me that arm is in the wrong position is the way the cable is adjusted. Assuming you have the right cable then the level is definitely not clocked correctly on the shaft.

    It was slightly different. Clutch pulled in had a little more travel.
