Default Fat boy low high speed wobble

Fat boy low high speed wobble.At 80 miles an hour I get a wobble like a death wobble. I have replaced tires, will bearings, swingarm bearings, but if I add weight as in a passenger it goes away

Check your steering head bushing adjustment. It's called a death wobble for a reason. Make sure there is no apparent oil weeping from front forks. Uneven fork preload and damping can also cause this dreaded scenario.

Thanks for the info. This all started with new tires .Was thinking bad rear tire and replaced with a new one again. Have had front tire balanced twice I will look into the steering head bushing tonight but could anyone tell me why with someone on back it goes away?I rode to Sturgis last week from colo. and half way picked up a friend.Was a nightmare to handle before and find with a person on back.On the way back great half way until I went solo again and the fight was on once again.

With a passenger on the back there is not as much down force applied to the front wheel and front suspension. But yea, if this scenario reared its ugly face right after installing new rubber I would suspect that is your gremlin. I assume you are running the proper pressure on tires but would be remiss if I didn't ask.

Do you have a windshield or a fairing on it?

Another thing. I know from being in the front end alignment game for a few years, you would not believe the amount of bad brand new tires. I imagine can happen with bike tires also.
