The original stopper bolt that I replaced wasn't in very bad condition. I just wanted to install one of my own.
My bike is a 2003 model with 17,400 miles. 8000 miles ago I installed Milek's primary spline adapter.
Because of all of this, I'm of the opinion that a healthy CVT doesn't wear a stopper bolt too much. I'm not familiar enough with how everything ties together to have an opinion on "why",..but I believe that a severely chewed up stopper bolt is indicative of a problem in the CVT.
Nothing wrong with that and its good for us as a group to learn.
I did Milek's adapter when I rebuilt mine with the updated primary (comes with the long stopper bolt). A best buy for these older diesels, lol.
That's what the general consensus is here I believe. We think the o-ring that is under the shim against the adjuster splits and partially drops out allowing the adjuster to move/vibrate more wearing the bolt. I've seen a few of those be split and fall out of place when opening the CVT. It's also possible the anti-seize used on the adjuster dries out causing it to bind a bit.
