you can blast a turn at 100 if you want to on these kings man, in my experience with the wobble it has usually been the lower motor mount bearing usually being worn out and once that is replaced the thing is straight as an arrow as you lean in the turns. (108ftlbtorque,98hp at 2500rpm) along with 20" apes on my king

 

What bearing are you referring to? There are no bearings on the motor mounts.

(There's two of us?)

Yeah.. the factory does a real good job with the suspension and the parts they're dealt.

 

Swing arm bushings
Worn motor mounts
Tire pressures
Damper issues
Driver experience
Wheel weights missing
Bad shocks or the wrong shock settings.

The above mentioned are all causes for the Harley Death wobble, some answers to the problem are simple, others are complexed.
The right combo to get your bike smoothed out depends on each individual bike.

Fixes include:
Proper tires, and tire pressure.
After market swing arm bushings.
After market shocks and springs.
Engine braces, many different brands, Bagger Brace, True track, just to mention a couple.
I've experienced the Harley Death wobble, and still have it in my bike, the only thing I haven't done to fix mine is the polymer swing arm bushing, their next!

 

It does seem like some of your mods were made without considering the diminished handling they will cause.

 

Loose the 21 and It will go away.

 

My 2010 ultra LT has had a bobble since day 1.I don't call it a wobble,its more like wind buffeting behind a big truck.I only feel it on interstate or 4 lane at speeds over 60 mph in a turn.It seems that if the suspention rebounds from preload do to uneven pavement,not even a bump it will bobble alittle.I have never had it do it on 2 lane back roads as the turns are sharper and speed is slower,just the longer sweeping turns on 4 lane highways.The bike now has 10,000 miles on it,I just got used to it thought that was the nature of the beast,I didn;t know there was a fix for it.

 

sorry dude, it was late last night. I was talking about the front lower motor mount bushing. I noticed that death wobble would immediately be gone after replacing that bushing. I've had 18-20" apes for about 4 different bikes since 2000 and have noticed the problem over time only when mount was worn. They say with all the low end torque as you pound the bike it wears out the bushing, just my 2 cents

 

Very interesting. Front lower engine mount. Ok I'll look into that. Replace it with stock or aftermarket who?

 

xjayx-

In my opinion, the problem you have is most likely related to the Progressive 412's you have. Yours are about 2 inches lower than stock, correct? When you are in a long sweeper like that, and at those speeds, you compress your suspension quite a bit. And since yours is already shorter, you are probably bottoming out the shocks and that's causing it to start the wobble. Since the bottoming is happening somewhat gradually compared to hitting a big bump, you may not feel it bottom out.

So you probably have to chose between looks and performance.
