Default Vibration

Hi guys. Back with another question before extremely helpful group on here.
Is there anything that can be done to reduce high speed vibration. From about 65 mph and up on my 94 fatboy eco?

Do you have pegs or boards on your bike.
If you have boards check the rubber connectors that attach the board to the platform.
If they are broke that can increase vibration in your feet.

Depending on miles on tires, a good spin balance from good equipment. If tires are worn and spotted, little but putting a new set of Mithelins on.

I am guessing your EVO is a pre balance cams TC. Whats that bad boy fill like at idle?

The bike has boards which appear in good shape. The motor is stock and mounted to the frame. Feels fine at idle and up to around 60-65. It also feels better if I put my feet on the highway pegs.

Also the tires are fairly new only a few thousand miles on them. I will get the balance checked.

Go Over the Motor Mounts... Check that you have fairly Soft [Not loose and Sloppy, and not Rigid] Handlebar isolation bushings.
Believe it or not... Check primary chain adjustment!!!

Your guess would be wrong.

Sorta worded that iffy . By pre balance cam TC, I meant a EVO that was sold mounded. Did early Softails with EVO motors have balance cams?

No. All Evos are the same. No internal balance shafts.
