After an install of an amplifier on my 2011 Road Glide, have very little to zero reception. I even installed a amplified antennae

 

There's a short list of amps known to not interfere "as much" with FM reception. Theres a much longer list of amps that do exactly what you're describing.

What amp do you have installed?

 

Welcome to the Audio forum!

Losing FM reception with most class D amps is very common. Which amp did you install?

 

2.) an "amplified" antenna will amplify not only radio waves ( good) but also "noise" ( bad) so you end up with the exact same ratio of music and noise.

antennas work best when upright, perpendicular to the ground.
with a "ground plane" which is the steel plate in the base of a tourpak, or the hood or trunk of a car.

Do you have a vertical antenna near the rear of the bike?

I use a rubber stubby from pepboys $12 and it gives quite good results- but a full size antenna on my tourpak works better
