Default Can I cut down my front springs?

I have a simple question. If I buy a lowering kit for the front of my 06 Superglide FDXDI, it looks like just shorter springs. Why can't I just take out the old springs from the top of the forks, cut the springs 1" with a chopsaw (with a stop) and put them back in? Seems simple to me. I am experienced in early auto mechanics (60s cars) and metal fab and have tons of tools.

Not sure, The shorter springs might have a different tension value.
Maybe someone else with more knowledge on this will know?

The metal spacer? I haven't looked inside but I know what you mean. I installed 6 over tubes and 6 degree trees on my Sporty and they had those water pipe spacers on top of the springs so I am thinking I know what you mean. Do they have similar ones in a stock 06 FXDI? Anyone got a manual handy?

If you take off your top fork cap you will have the spacer, then the spring. Watch out.....there is alot of pressure behind that cap when you take it off. Might want to take all the weight off the front end, and still there is pressure.

Shortening the spring or the spacer will not lower the front end. It will decrease spring pre-load and make it softer. Not necessarily a good thing.

Open your manual and take a look at how the front end goes together. To lower it, you'll need to place a spacer deep inside the tube. That's the only correct way to do it. Not technically dificult, but requires some work.

For my bike, I lowered the front by moving the forks 3/4" up higher in triple trees. Simple, easy, free, and still retains full suspension travel.

When you cut down a spring you actually increase the spring rate (it stiffens)
