Default Nightster Fork Springs

Well I had planned on trying to just add some spacers to the existing fork setup. I changed my mind after I jacked up the bike and pulled one of the caps off today. The stock spacer sticks out of the top of the fork tube almost 2". Wow that is way more preload than I thought it would be. I guess I will just wait until somebody finds a better solution. I think I can live with it the way it is for a while. I don't think I could possibly get a spacer in there for more preload enough with a second body helping me.

I did pull the spacer out and pulled the springs out far enough to verify it is definitely progressively wound.

Can anyone tell me what kind of stock preload other sports have compared to this approx 2+" preload?

Thanks for the report Ken. Did you happen to measure the stock spacer while it was out?

Like an idiot I did not measure the spacer. It was however at least 10-12" long

Your stock springs probably don't have a spacer. The Progressive springs were shorter than the stock springs on my "04. Stock springs, on my bike, stick out the top of the tube an inch or 2. I measured the difference between the 2 sets of springs (can't find my notes) and the stock springs were like 22 1/2" long compare to the Progressive's which were like 18 1/2" long, hence the need for spacers. Don't quote me on those numbers, but they're close.

Anxious to hear the solution for the forks. I have the standard length Progressive springs and waiting for info before I tackle it. GOOD LUCK!

Thank you Johnnybgood.
Because you had 1-2" of spring sticking out of the top of the tubes of your 1200C I decided to go ahead with the spring replacement. I had ordered the standard springs for the sportster a couple weeks ago. I removed the old spacer the old spring installed the new spring reused the washer from the top of the old spring and then used the full 3" length of the spacers that came with the new spring. This gave me about 3/4" of the nes spacer sticking out of the top of the fork. I think this is a bout the right setup for me and my weight. I now have 3/4" of fork sag with my full weight on the bike.

Here is a link to a picture that shows the shorter stock spring and spacer next to the new spring. The progressive brand is a thicker coil material than the stock spring.

The ride is definitely better on small and large bumps. I just need to fine tune the 12" 418's that are on the back get a more comfortable seat and I should be all set.

Glad it worked out for you......they (Progressive springs) were too stiff for me.

Did you have fun getting the forks caps back on? I have read every little trick on the forum about getting them back on easily and found a trick of my own.................a helper!!

I marked the caps with a marker without the spacers in. Then i put the spacers back in. put the cap into the socket and pushed down on the top of the breaker bar. It took about 10 seconds to get each one lined up. So I guess it wasn't bad at all.

Must just be a problem for some of us little people.
