Having a vibration over 70 mph. Started about 6 months ago. Makes things blurry. Changed shocks( to Ohlin), replaced motor mounts front and rear-- Predator front and oem rear. Rebalanced both wheels All with no help. Actually a little more vibration. Nothing is touching frame. No noises. No wobble. Nothing loose.
Next is to check swing arm bushings.
Any other suggestions.
Thank you,
Roger

 

I would get it on a Dyno and check if it is motor, or the drive / wheels.
All you have done so far is "Shotgun" the problem. Yes replacing the motor mounts, shocks and rebalancing the tires are regular maintenance for a bike of that age and was worth the money.
Who did the motor mounts replacement? If the motor wasn't checked for alinement that could be a problem. If you have the manual you can do that yourself.

PS: been there and done that. Wish I had had followed my advice. Now I have a "NEW" 2005 Ultra.

Tires.....or air pressure in em

 

Maybe unbalanced tire(s}. I once had an `09 Dyna. It had a little vibration at high speeds that I couldn`t figure out either, but it wasn`t bad enough to bother me and it didn`t show any problems. `Could be just the nature of that bike model.

 

At 70 with no windshield, it could be the wind hitting you in the face if you are using an open face helmet. Have you ridden it with either a face shield, as in 3/4, or full face helmet ? My Dyna will do the same thing depending on the helmet I'm using at the time.
