Swingarm issue
Hi everyone. First post here. I have a 93 fxr with an odd problem. I have a hard vibration that I think is coming from my swing arm. I had a bearing kit in it before. I suspected that may be the cause of it, so I put delrin bushings in it last week. Today, I rode it about 300 miles. It was ok when I started, but the vibe came back.
it feels like it’s coming from the rear. I can feel it in the seat, pegs, bars - everything. One thing I was particular about was making sure the pin in the swing arm support bracket was centered in the rubber isolator on both sides. Looking at it now, I see that the right side has rotated. It’s not much, but I wonder if that’s enough to cause a problem. Was I supposed to lubricate these parts somehow? The swing arm bushing just slid right in the left side. I could push it in or out by hand. Is that a problem?
one other question - how are the oil lines and rear brake line routed over/under the swingarm? My oil return goes under the trans, over the swing arm and then around the starter. The brake line and reservoir hose run alongside it.

I believe so. I had to use a press to get mine in. No need to lube anything except I use anti-seize on the pivot shaft. Yeah re-align the support rubber so the pin is oriented, but I don't think that is the source of your vibration. How's your wheel bearings? I've had bad ones cause vibration and high speed wobble.
