I took a road trip to the beach on my 99 electra glide with some friends this weekend. As soon as we left the guy riding behind me said something did not look right about my bike sometimes. he said it looked like the back was dancing around alot. I had been feeling a difference before that but thought it may be due to not riding all winter. I noticed the wobbeling more at high speeds 70 to 85 MPH. ( I usually dont ride at those speeds but had to keep up with everyone else) I ended up riding back home by myself because I had to leave earlier than everyone else and we thought that we had got it fixed by adding air to the back tire because it was low (Few Pounds) and that did seem to help, but I did not hit 70MPH plus till on the way home and it seemed worse. when I did finally get home after the 604 mile road trip (longest trip since I have owned it) I searched harley wobble and was scared to death!!! Was and still am thinking about a stabilizer kit but decided to look at everything I could to see if I could see anything obvious. It took me about 10 minutes after looking at the rear shocks and swingarm to move to the motor mounts...What I found was kind of scary. I have a missing motor mount bolt on the top motor mount. It is the bolt that secures the rear cylinder to the mount. I am almost certain this is the problem and I am sure everyone will agree that this is probably the culprit of my problems but I just wanted to share and see what everybody else thinks.

 

Had the top motor mount break on during a return trip from Sturgis a few years ago on my '99 Ultra. My riding "discomfort" was worse when I went into a curve, press right or left and the motor pretty much tried to counteract by not leaning with the bike.

Stopped at Jack's HD in Effingham IL who confirmed the motor mount was broken. They didn't have one in stock but told me I'd be OK to get home as long as I was careful in the turns. Home dealer replaced it and said HD asked them to return the broken one for further inspection.
