Dyna alignment
How many miles on the bike?... I changed my neck bearings out because I was doing a major change of the front end.. and "I was in that far....so.. "... but truthfully the bearings looked fine at 62k miles.

I put the frame straight, measured the angles of the brake discs and found a difference of about 2 degrees (using my iPhone). I then took a shot of the bike to confirm the misalignment. It looked like this:
How my Dyna aligns right now.
According to the manual, which I looked into at a later occasion, only one degree of misalignment is acceptable, and it suggests adjusting the stabilizer link (which is holding the top of the engine to the frame) so that the discs align up with each other. I will try this later.
For now, I am curious about what kind of experience you all have in this matter. And I have a couple of questions:
1/ Do I have to remove the petrol tank to reach the stabilizer?
2/ If it is impossible to get a good alignment by using the stabilizer link, which is the most likely reason for the bike not aligning?
(To this question I have some thoughts about the front fork not being straight as the bike had an accident with the previous owner.)
Advice and recommendations are much appreciated.
At last I have made two moves in trying to align my bike.
1/ I loosened the rear wheel and adjusted its axle to be straight to the swingarm.
2/ Following the Harley manual, I lifted the bike so it rested on the frame with the rear tire not touching the floor. Then I loosened the tank, detached the fuel line and raised the tank with a support.
After the top stabilizer link was removed (on the left side of the bike), the top of the engine leaned itself to the right whereupon a missalignment between the stabilizer and the engine mounting bracket of about 1/8" occured. With the help of a straight level placed on the frame and a small magnetic one attached to the rear break disc, I could now confirm that the frame and the rear wheel were in a much more correct angle to each other than they were before.
After not being able to adjust the stabilizer link, still attached to the bike, I took the link out and shortened it to a length where it aligned with the hole in the mounting bracket on the bike, thus not creating anymore tension between the engine and the frame.
Torqueing the mount to specifikation and putting the tank on place, I took a test ride. Immediately I found that the bike had received better balance and that the handling was greatly improved.
These two actions, recommended by the manual, have made my riding much easier, and the bike is now more steady, both when riding it straight as well as taking it through corners and bends.

I have enclosed pages from the 2006 Dyna manual, as well as a page from the "M1324 Dyna model vibration".

Since this is a PITA, it's almost as good if you level the frame under the seat. Finding something that is a good vertical reference is difficult.

Anyway, thanks a lot for sharing this method.
