My left side rear wheel is about 1/4" and right side s about 3/4". Now last night my wife and I went for a sunset ride and we noticed a "chirping" noise coming from the left side rear! Seems like nothing is rubbing as we stopped and looked. It seems to only make this noise when doing 35 mph or better. And the noise doesn't seem to really increase in "rhythm", just in sound. I'm baffled.

 

I'll have to look at mine. I did notice my front finder looks off a bit. Been like that sense I bought it.

 

On my 2014 fxdb the backwheel is offset 2,5 cm to the right side when you look at the bike from back, was like this from the factory, bought it from new, irritates me like hell, that the wheel ain`t centerd under rearfender.installed the true track and its still the same

 

I recently bought an '03 sport, all original, even tires. It had less than 6k miles. I changed the tires and noticed that the back wheel is off center to the right enough to make the back brake bind in the caliper. I'm thinking of making some new spacers to get it centered correctly. Right now i have it adjusted so it's not binding, but it aint right. I was really scratching my head on this one.

 

Funny this post comes back from the past.
I stopped by the local body shop last week and had them look at possibly pushing my rear fender struts over about 3/8 inch so it will be centered. They said no problem and they will make sure to measure it a bunch to make it perfect. I yet to get the price from them but I am eager to get it done.
Since posting this I have lowered the bike and chopped the fender and its is SO noticeable now. I HATE IT NOT BEING CENTERED!

 

Take another look at the space between your struts and the tire. Is the distance the same at the front of the tire and the rear of the tire. If not check the rear wheel alignment. If the alignment is off the rear of the tire will be closer on one side than the other while the front will be farther away from the strut on the side that is closer at the rear. Since you have had the wheel off it would have been very easy to put back on and not get it perfectly aligned. Measure the distance from the center of you swingarm pivot bolt to the center of you axle on both sides. You will need to be pretty accurate because just a half turn on the adjuster can throw it off more than you think.
I almost forgot. Remember these adjusters also adjust the belt tension so if your belt tension is good back off on one side half as far as you think you need to and tighten the other side the same amount.

 

I just changed my rear tire and almost forgot to align the wheel. I have already had to rewire my rear lights once before and do not wish to do it again.
