I had an 08 Dyna that would wobble when the rear tire got low. Not Bad but just enough to be concerned.

 

You might consider updating you swingarm cleve blocks to newer style spherical bearings.

additionally you might want to look into one of the many "stabilizers" available, I'm partial to Sta Bo for a simple, inexpensive, and effective product.

 

The day i picked up my 2008 FLHRC from the Dealer it kinda wobbled/wallowed threw long sweeping corners .When i got home i found the tires were a little low and only 10lb in the air shocks . i put the front at 38lb and rear tire at 40lb . pumped the shocks up to 25lb .............no more wobble

you might check the stearing head ajustment also

 

My bad, welcome to the forum

 

My 06 does the same thing too, its not to bad now, but it used really clinch my but cheeks right around 85 mph . The interesting thing I noticed is between 80-85 mph the front end felt like it was on the edge to going into a tank slapper. Get up around 90 mph and it smoothed out. Do you have spoke rims? First thing I did is tighten my spokes. There were quit a few that had that thud sound. Also I was running my tires around 35 psi. Now I keep them around 40-42 psi and its much better now.

 

Unfortunately that is an all too common problem with HD's swingarm design. Depending on how hard you like to ride it can become an unsettling feeling. Check out Glide Pro - this guy created a fix for the problem and not just an external add-on part.

Tell us where you think the wobble is originating on the bike. You never specified front or rear. That would help a lot with suggestions. Does it do it more on decel than accel? Does it do it in straights only? Are your shock bolts tightened to specs? Have you had your steering head bearings checked? How about your swing arm bearings? Have you checked your wheel bearings? See, there are these and many more that could contribute. So it's good to know a little more about which end of the bike seems to be wobbling.

 

Maybe keep your speed lower. Does it happen at 70 or 75?

 

Mine did it and i put heavier fork oil in and VOILA....oh and i tend to ride a bit more conservatively also...
