More "Wheel Fit" Action!

[snowflake]

I am looking at upping my FXD to Twin Disc Front End and got hold of a nearly new ('05) Sportster set of forks, complete with twin discs, calipers, risers and hosing after being advised that this would slot in nicely on the Dyna - which I think (read 'hope' ) it will.
Question is what do I need to do to my front wheel to make it accept the twin discs and will it then fit in the new forks, or will (as I suspect) I need to get a new hub and therefore might as well get a new front wheel?
Hope I haven't been too much of a dope buying this...be kind to me....

two points to pick up on, wont the sportster forks be a bit of a light weight? just a tad under rated weight wise?
can you use your old fork springs?
if your hub hasnt got the tapped holes all ready to receive the brake disc, would it be worth investigating getting it machined?

What year FXD?

Simon touched on nearly all the pertinent points.
You will need to swap fork springs as they are different.
Depending on the year you will either have wheels that have blanked off holes ready to accept a new disc, or you will have a hub with one blank side. By far the easiest way is to have the hub machined & tapped.
Your other issue is the brake Master Cylinder. For a single disc set up you will have a 9/16, to generate enough volume for dual disc you will need to switch to an 11/16.

Thanks for that guys.

My FXD is 2001 the Sporty Forks are 2005.

As for the hub, I think it will need machining - that's what led me to post this thread. I'm not sure about the machining/tapping - is that easy/cheap to do or is it better to get a new/2nd hand hub/wheel?

Sorry about all the /'s...

I was going to put some Progressive Suspension Springs in the front, I'm assuming I can put Dyna ones in. As for the twin disc setup, I have already got hold of the 11/16" Master Cylinder....hopefully.

Machining the wheel should be a simple job for any machine shop. All that needs to be done is drill & tap some holes, it just has to be precise.
You/they can use a brake disc as a template.
Put the progressive kit in, works great.
