Vibration Damper Question

New guy here with first question, I'm hoping somone could lend a hand with some info please.
I have a 1998 Fatboy that vibrates to the point that my legs shimmy off the floor boards and my azz goes numb after an hour.
I was reading about a product called "Vector Vibration Damper" which claims to reduce the vibration by half......anyone own this product or have any info?
Thank you for your help I have enjoyed many good posts here from all of you.

If your Evo is vibrating that much, there is a problem - loose/broken motor mount, engine getting ready to take a dump, especially the bottom end. Cure the illness, don't treat the symptoms.

Poco get's my vote, UNDER NORMAL conditions.
OP, how many HDs you ridden or owned? How old were they?

I have had peeps come in, saying the vibration is KILLING them. I take it out, smooth as silk, IMFUO. Sorry, these things are NOT Beemers.
When I ride someone elses 'newer' HD, I am AMAZED at the smoothness. (WELL, maybe mo' jealous, THAN amazed.

)

BUT if yours is indeed shaking your feet off the pegs/boards, START looking.

The first thing I do, is determine 'source'. Is the vibration 'engine speed related' (RPM) or is it 'rear wheel' related (MPH). This will get you 'narrowed' down rather quickly, and then you can proceed from there.
Jus' a suggestion.

I am having a pretty bad vibration problem on my 93 FLHS, The first 135,000 miles were smooth, now I have changed the swing arm pivot shaft, rubbers, and the front motor mount I even bought a new Velva Ride V Thunder mount. I changed both stabilizers with OEM Harley stabilizers. And it is vibrating pretty bad. I took it down to one of the local HD shops here and they want it out of the shop. I was hoping they could at least tell me if the engine is about to blow up but they say it is most likely the rear end? So I am going to take it back and start allover with algnment,etc. As they say it would be cost prohibitive to fix.

No info on the "Vector Vibration Damper" sorry. But I give a plus on the engine alignment along with the visual on the mounts and everything else that spins before you go throwing money on accessories that band-aide the cause...
