new to me 04 roadglide. 40k
severe fairing vibration at 2-2200 rpm vibrates windshield bad, knocks off CD player until 3000 rpm.
handlebars seem ok ,footboards good (does this both riding and on jiffy stand)
I have replaced front engine mount, have the fairing off ,checked the frame to fairing mounts..
checked exhaust system (replaced muffler hanger rubbers)

help me to check anything else

 

Have you checked the well nuts for the windscreen to the outer fairing?
How tall is your windscreen??

Check the screw mounts on the outside fairing. They may be cracked.

 

well nuts good, 9 inch windshield,
I'm thinking maybe a tune would help. It is pretty smooth when starting cold (EFI)
then when the "cold" circuit kicks out it idles pretty rough ( also gets 50 mpg at 70-75mph)
maybe a little lean on the fuel ?

 

Did you check the frame rails that go up on either side of the radio inside the fairing? T Hey break once in a while.

 

Does it have OEM or aftermarket speakers? Are all the supports installed to the speakers? Some times with bigger speakers they don't fit correctly and get left off.

 

Agree. The inner fairing bracket tend to break. I replaced my with Alloy Art Strong Arm Inner Fairing Support Brackets.

 

yes checked from frame to the radio, pulled outer fairing, going to my indie today

 

My 07 did this and the inner fairing brackets were cracked at the top where they bend, I repaired with a couple elbow brackets from home depot, drilled a hole into the bracket and screwed the elbow bracket in place, Vibration gone.
