rear wheel vibration
I have searched all over the net and i cant find any kind of answer. I have an 07 FXST. what happen is i took it to a local shop to get a new tire put on. when i got it back i noticed at 30mph and exactly 21mph i get a vibration in the rear. it happens with light coasting and also light coasting with light brake. It feels kinda like an over inflated tire on a rough road. It didnt happen until they changed my tire. Now they did say that the rear wheel was pretty far out of alignment as well so they put it all back to spec. I even took it out of gear and coasted it with the engine off so i know it isnt tranny related. It is very annoying, the worst part is the mechanics say they dont feel it at all. I asked them to check it serveral times and they said the rotor was warped and it needed to be replaced i had them do it and no change. so new tire, new brake pads, new rotor and still does it. Im kinda pissed at this place cause i paid for more parts for them to try to get more money and it didnt fix a thing. any help would be appreciated. Btw i went from a metzler to a dunlop.

Measure from center of swingarm pivot bolt to center of axle on both sides to ensure bot are equal distances for proper alignment. Also check for proper belt tension. If both are proper I would question the tire's balance. I would remove the weights and install dyna beads.

Many things can cause a vibration but obviously the vibration is related to the work you had done, so you have to back track from there.
Call Harley-Davidson Motor Company Customer service (800) 258-2464 and see what they can do to encourage the Dealer to address the problem that apparently they created.
Didn't have the work done by the Dealer?
Then you are probably screwed as far as getting the Indie to fix the problem.
You should just bite the bullet and take it to the Dealer and see if they can diagnose the problem.
Just don't drop it off with a vibration complaint.
Explain to them what exactly was done by the Indie so the Dealer mechanic doesn't waste time checking unrelated suspected problems.
I know some on this forum have an Indie they swear by and if you're lucky enough to find one that's great, but the problem you are having is why I have the Dealer do all of my work.
Are they the best? Probably not. Are they the cheapest? Probably not.
However they have the manufacture behind them which provides tech support and if the Dealer gives you grief in addressing an issue you have a escalation path through Milwaukee.
So just take it to the Dealer and bite the bullet on the additional cost.

First, find another shop. Bring it somewhere else and have them check the balancing. Better yet, pull it yourself and have it balanced at a different shop then put it back together the right way. You will rule out the alignment and belt. If it still does it, I would think tire. If the rim was bent I think it would be at all speeds. You could borrow a jack from a buddy or buy one. They are inexpensive enough. Good luck.

If you are able to do your own wrenching then I would get the part's breakdown of the rear wheel and swing arm assembly. Then inspect the rear of the bike to make sure that it has been assembled correctly. The correct spacer is on each side. Also inspect the wheel and if you have spoke wheels check the spokes. Also check all the nuts and bolts (Including shocks) make sure they are good and tight. Also check the torque on the rear axle nut. Next thing I would check is the balancing of the wheel, BigMesa mentioned Dynabead, I would also recommend them. I have them in both of my wheels and my buddy is also running them with no problems. The nice this is they take all the guess work out of balancing your wheel.
If you are not comfortable with doing your own wrenching. Then as suggested find a different shop.

What brand tire is it? What is the date code on teh tire? It is a 4 digit number like 3813 on the side of teh tire. It could be an older tire that has been sitting and has developed a flat spot from sitting. I have had a few issues with stuff like this in the past.
I would use Dyna beads as well but there are a few different things that can cause this sensation including the tire itself. Also., what kind of air pressure are you running in teh tire? Try the max PSI listed on teh sidewall of the tire.
