I'm trying to do some preventative maintenance on the swingarm pivot bearings and install a kouba lowering link on my 2000 XR650R. The bike is new to me and I'm not sure how long it's been since it's been taken apart. I've gotten stuck on a couple of things: 1 - On the linkage, I've gotten the nut off the right side of the forward connecting bolt, but the bolt doesn't want to come out. I thought maybe it was threaded in from the left, but turning the bolt from the left side with a hex wrench didn't do anything. If it's just stuck, I'll get more aggressive and force it out, but I want to make sure I'm not missing something. 2 - On the swingarm pivot, my understanding is that the bolt should loosen like any other. I laid into it pretty hard with sockets on both sides with no success. I understand the need for the special spanner for the preload fitting, but that's a separate issue - correct? As with the linkage, I'm prepared to take more severe measures to break things loose, but don't want to overlook anything. Thanks a bunch.
