well i got it installed and I cant believe the difference it made. That thing must have been going bad ever since I bought the bike. It shifts better than it ever has, there is not as big a clunck when I down shift into first and it no longer wants to keep moving when i pull up and stop at an intersection. It shifts so much smoother, I'm a happy camper!!!!!!

When I installed an aftermarket clutch cable and adjusted it myself things got a lot better than stock.  I am going to intall a ceramic ball between the clutch activating rod when I install my new clutch plates.

Hello Everyone,
Last weekend it happened again (for the sixth time in sixth year) and I was returning home with the clutch not working.  Originally I had the so called "fish hook" design assembly which was very effective in braking the cable ends.  A couple of years ago I learned about the "2006 and later" COA  so naturally I ordered one hoping that the clutch cable issues would become thing of the past.  Yet after about 3 months sides of the swivel part just came apart.  Well, I decided that using just drill, hammer and vice I can easily manufacture such part myself in my garage.  The resulting piece despite its shabby appearance definitely assures reliability.  That was last summer.  At this point I  was confident that nothing can possibly go wrong with my improved COA anymore.  Well, couple of days ago I found out that it could and it did.

Is there somewhere a COA that will work without a failure or do I have to design and manufacture such part myself?  Thank you.

Wow. So it broke the metal at the base of the arm? I wouldn't think there'd be that much pressure on it...I was always amazed at how little travel there was on the clutch rod

Link to thread on clutch release mod.

 The pics in the thread are also in the photo gallery and have a few notes under them there.

The swivel link looks like it only has about 1/16" of material above the cable attachment hole/slot.
If you increase the amount of material above the attachment hole/slot to something like 1/8 to 3/16 inches (assuming there is nothing above it to cause it to interfere), I'm sure the new link would last for years.

The broken arm could have been part of the reason your cable link broke but whatever, that part definitely needs to be replaced.

Thank you Ice.  I have been considering such mod but I was not sure if it would work.  Apparently it does so I think I am going to give it a try.   :)

Arizoni, the broken swivel link shown on the last pic is the original one that came with the COA.  It broke shortly after installation and I replaced it with the one currently attached to the arm (that's the one I made myself).  This link appears to work fine.  Now it is the arm part of the COA that I am concerned with as it lasted only about 2k miles and it came as a shock to me when it failed last Sunday.

 There are two pieces of steel rod and a single ball bearing between them that transmit the motion of the release mechanism through the hollow transmission shaft to the clutch pressure plate located on the opposite end of the shaft.

  What I surmise has happened is this; the clutch push rod halves formerly flat ends have become concave due to wear and bedding of the ball between them and the rods have in effect become shorter over all.

 When this occurs the clutch begins to drag and the cable numerous times to compensate.

 Now the rotating arm travels a bit further before stopping than it formerly did.
As it travels, the roller balls move it sideways via inclined plane action provided by the three opposing indentations of the two main halves of the release mechanism. This increased travel results in the rotating arm half moving outward more than before.
 
 With the cable housing end still being fixed there is now more side load on the end of the rotating arm.

 Were it my bike I would order one of the low friction ceramic ball bearings from ACE cafe and instal it, decently greased of course, between two new rods. The sharp edges of the replacement release mechanism would be polished to a modest radius to eliminate stress risers. The mechanism would be installed and adjusted per the manual and then the cable adjusted after that.   Please take note that as far as cable ends are concerned the release mechanism in the linked thread is of the pre-06 variety, otherwise the two are like.


The red lines denote one edge of of one area I would polish.
