    Approx. 4,000 miles ago I replaced my Sportster XL1200C (@59,000miles) slipping clutch with Barnett's Extra Plate kit. The kit had worked fine originally after install, but the other day the clutch/drivetrain completely went out. The bike will not take off from a dead stop.

    Can I rule out that this is not the clutch plates and another issue?
    Could this be the clutch hub assembly and spring plate have gone bad?


    Hopefully, I can pin-point what the problem is with my clutch/drivetrain from replys.

    If it doesn't make any noise when shifting into gear I would look at your front drive pulley behind the rear master cylinder. They have been known to wear out the splines.

    I will check the locking plate per Tourbox suggestion. Tourbox: little to no noise when shifting into gear. Is there any other wear parts that I should focus on (narrow my search) too get me back up and running?

    Not really. After verifying the the pulley & locking plate are OK the next step is the clutch itself or adjustment. With very little noise when putting in gear I wouldn't think it to be adjustment or excessive wear. If the center adj. screw is to tight it cause the clutch to be disengaged all the time causing the slip.

    tourbox- I removed the front pulley cover to check the condition of the locking plate and pulley. All components appear to be tight. I did not remove the front pulley nut or remove the tension of the belt. Prior to my problem the clutched seemed to engage/disengage function properly. Question: I noticed my clutch hub have some play to it. I took a video with my camera, not exactly sure how to post.

    There is a stepped ring between the diaphragm & pressure plate. It is held in place by a retaining ring(snap ring). If the stepped ring came loose you will loose clutch operation. The stepped ring has a particular direction in which it has to go. I can't remember which way though. Itf it came loose I think you can see it floating around after the outer primary is removed. Can't seem to remember that either,OLD age ain't for sissies.
    That ring came out on a friends XL and I had to go get him with a trailer.

    Snap rings are installed with the rounded edge in, square edges out.

    The snap ring retaining the spring plate was not loose. I was referring to the outer clutch basket assembly that is attached to the starter sprocket. That part has minor wiggle room, but I kind of think that is normal. Is this correct?

    I removed the retaining ring, spring plate, and clutch pack for inspection. Without any thing to compare to I would say steel and friction plates look fine. The only thing I could not get out or my patience gave up on me is the little steel ring from Barnett’s clutch kit.

    I should have tried to adjusting the clutch before disassembly, but will leave it open as I opted to order a heavy duty spring plate.

    Does anyone have Barnett’s extra plate instructions that they could post?
