Clutch Question

[Mhanis]

Dudes,

It is actually about the lever I guess. At 63,000 miles and climbing I guess a clutch issue shouldn't be a shock, huh? Anyhoo, the bike has occasionally started to creep a bit (VERY lightly) when I have the lever pulled all the way in, but not all of the time. I was thinking I would just move the little adjustment pin a bit to account for that and buy myself some more time. I went for a nice ride yesterday and when I got home I swear that the lever is "bottoming out" earlier than it had before. I think it used to come all the way back to the grip, now it is fully 1/4" away from the grip before I meet strong resistance.

Is there something odd going on or is this a case of "Um, you got nearly 65,000miles outta the clutch, replace that shit!"?

Most likely a slave issue if you have bled the clutch lately.

Be worth looking at the clutch slave for a slow leak and the basket and plate tangs for chewed up wear that makes for a dragging and grabby clutch. Does the fluid level mysteriously drop? Leaks behind the slave? Check the pressure plate bearing too.

[Mhanis]

Well that was a short lived endeavor.........

I opened the reservoir and it seemingly isn't low on fluid, though it has been a long time since I have had it open. I figured I'd remove the slave and check it for signs of leakage. 2 of the 3 bolts broke away easily, and........ you guessed it, the 3rd MF'r stripped. It is the top left one if you are looking at the slave. These bolts are recessed in the slave so the ONLY thing showing is the rounded head, nothing to grab from the outside.

Any suggestions?

A pic would help heaps. I'm thinking helicoil or Timesert thread repair or if its wrecked a new, used cover. Those bolts are not a high torque job. Has the bike been down?

By "broke away" you mean unfastened? If the thread is stripped that bad it might come off by unfastening and pulling on the slave at the same time.

If the problem is just that the hex is stripped out you might be able to get it out by hammering in a torx, as koko said, it shouldn't be tight.  Another alternative is a left hand drill.  Also, something like this  https://www.sears.com/craftsman-7-pc-drill-out-screw-out-power-extractors/p-00952157000P  or this  https://www.toolpan.com/Irwin-Hanson-1876225--6-Piece-Impact-Screw-Grip-Double-Ended-Screw-Extractor-Set_p_30601.html?gdffi=d5de8d975e554fe98677ff5f83efd439&gdfms=1689B914BFEA4C598238F1F25999890F

I'm thinking it's the hex that's stripped, and pounding in a torx bit will typically work on a low torque fastener like that.

Another option is to use a drill to just remove the head of the screw and then vise grips to remove the threaded portion.

[Speeddog]

What DP said on the Torx, I think that's actually what the torx was designed for.

Next, Howie's extractors if one will get a grip in the fuxxored hole.

Failing that, a left hand drill in the size appropriate for the extractor.

If the drill doesn't get it, then the extractor.

If still no, then 5.5mm drill is good to remove nearly all of a 6mm shank and a little bit of brute force on the head it'll pop off.

At that point, shank should twist out by hand or with pliers.



If the shank won't come out, report back and that'll be phase 2.



I've seen weird stopping of the lever when the clutch basket nut gets loose and starts backing out.
The master and slave will happily adjust out to follow it until the slave bottoms out, which gives the early lever stop.

[Mhanis]

Thanks for all of the advice, I'll try the Torx first and I'll keep you posted.

I did take a picture but my Photobucket account seemingly doesn't exist anymore. What are we currently using to post pictures?

Torx to the rescue! This is why I couldn't get a hold of the head of the bolt, it sits recessed inside the slave:

Anyway, all looked normal with the slave, no appearance of leakage of fluid.

Here is what my basket looks like, I know I am on borrowed time with this:

Here is a quick video, it seems to me that the plate simply isn't moving out enough:

Thoughts?

Theyre buggered.
The tangs will drag in the slots causing clutch drag. Time for a new basket and plates and maybe a hub/drum.

[Speeddog]

What he said ^

I use Barnett baskets and OEM or Ferodo plates.

At 63k a hub would not be a bad idea, those wear under the star washer and eventually get funky.
