Everything was going well, I hung the bike earlier, made a little tool to compress the springs, popped the seals out and then the springs...

Uh, look at the fork lengths. That doesn't seem strange? The bike handles like ****. Now I know why. But which is the correct length?
 
The spring on the left is 14.28 and the one on the right is 15 7/8. How in the hell...

Ha! Didn't even look at them. I guess I was thrown off by the title "fork seal". And I was looking at the hole you cut in the ceiling to hang your bike!

Just checked the book in the off chance there was a reason for two different spring lengths, but there is only one part number so someone has rebuilt your forks and grabbed whichever spring was closest at the time. Somewhere there's anoer motorcycle out there riding like **** just like yours.

[/img] The longer spring came from a model number ending in AMB. The short one says AMA. Rev A and Rev B. You like that hole! Necessary evil to get **** done! This was just supposed to be a simple fork seal job that has turned into a hunt. Now I have to deal with Harley again! Last week I denoided the bike and had to get a resistor from them.
 
Where are you getting the part numbers? It doesn't look factory to me. Someone put a higher spring rate spring in (the short one). Probably from Race Tech.
Perhaps take advantage of the mix-up and get the right springs for your weight from Race Tech (they come with the right spacer), instead of stockers from Harley.
I bet you get better and faster service from Race Tech:D

Whenever theres a problem.... Upgrade!
 
I too absolutely love the hole in the ceiling. Excellent! For what its worth hardly ableson does sell entire lower slider with springs for 162, just make sure you are very clear on r or cr as one is black and one is silver. I know this because hd f'd up my order!

[/img] This ******* sucks! How in the **** was I supposed to know some ****** moron installed the wrong tubes in the past. I mean I have bought stuff used plenty of times but never this.
 
I don't have an 1125, so excuse me if this is a stupid question, but are the springs supposed to be different lengths?

I only ask because on my BMW, one fork is dedicated to compression, and the other to rebound. The internals of each fork are consequentially different....
 
Good question, but the manual states the spring is to be 14.28 inches in length. One is, but the other isn't, wouldn't it specify?
 
Correction, when I put the axle in they are exactly the same height. But I still have 2 different size springs. Are they supposed to be the same?
 
I would call or email EBR and ask them. Most of the time HD service people just shrug their shoulders and say, I dunno know.
 
Even if one fork is dedicated compression and the other is dedicated rebound for shock valving (like a BMW) the springs will always be the same rate, and the fork tubes will certainly be the same length!!!
First time i've ever seen that one... Glad they're cheap!
 
After some research this is what I found. Tubes the same length. Short spring is an early 08, long spring is from a later model. So I get the spacer and spring from a later model and I should be fine as long as the damper assemblies are the same.
