Have to say I have taken the more experienced forum members advice and added this to my 12K.
On my first 12K a few weeks ago, I did it and it made a big difference, and that in only 12K, well almost 13K because of procrastination on that first time jitters on that sweet gas/air filter arrangement
I though it important to see how it comes apart before I needed to see on the road at the most inopportune time possible.
I had the updated linkage from our own forum member but I did not put it in. I carry it in my tool kit as I have since I bought it. Now I know how to install it in an emergency.
I took them all off, cleaned with Dawn, toothbrush, and hot water. I used emery paper to do the ball of the pegs and the beveled receiving lip on the sockets. Easy does it. Sprayed it down with brake cleaner and used a molly grease I have.
One thing is if you get a lot of grease in the cup, when you go to push it on the ball it will be very hard so go easy, and push evenly to allow the grease to ooze out, wipe it clean, and insert the clip/pin.
Well worth the time to do on a 12K.
