Single disc conversion
Ok so I got a 06 nice chrome wheel and I want to go single disc up front on my 97 Road King. I am wondering if I need to change the reservoir? Also the rotor for the 06 appears to be slightly narrower pad surface. Will that be an issue with my 97 calipers?

Some good information on single disk conversion here http://wanaryd.com/convert-to-single-disk.html

There are two distinct master cylinders, one for single rotor, the other for twin rotor, the difference being a slightly larger ID for the twin version. Outwardly they look the same. It would be wise IMHO to do the swap.

Me??? I really like smaller diameter MC, long as the volume is enough for the Calipers... which it certainly will be on a Single Caliper vs Dual.

That is not what he means ( I think)
The bore would be different.
A single disk will need more pressure.
At least in my world, it would.
The large bore for the dual, a smaller bore for a single. (hydraulic advantage )
You could try what is there....see if it stops ya.....

The OEM single caliper system on softails is absolute crap for breaking.
You would do much better to go with a caliper that has more than one piston.
Personally I wouldn't use that 06 wheel as it has sealed bearings and when they fail there is a high possibility that they will take the wheel with them when they go.

To all of you offering your thoughts, I am new to Harley and so really appreciate the information. They are sealed bearings and to answer the question why I am doing it this way is a lack of money! Im taking out the stock spoke wheel which my grandfather had sprayed something on and burnt the spokes so it looks like crap. I found this 06 wheel For $60 and I found a pair of 06 rotors for $20. All the advice Ive been given so far causes me to believe I should use both rotors Im still concerned though because when I hold up the 06 rotor to my stock 97 rotor its clearly a bit narrower and so I am thinking the pad will be too wide for it

However the problems of EVO era front single disk braking systems on softails remains the same....they suck.
That said converting yours to dual disk will cost more than simply getting a multiple pot caliper that will bolt onto your slider.
If you insist on running the sealed bearings at least make sure you use All ***** bearings and not OEM ones.

I've had problems with sealed bearings on more recent bikes, but not with later OEM ones. Like so many things Harley, the reputation and memory for bad stuff in the past tends to linger. Harley wheel bearings of all types however are bog standard industry stuff and are available from several if not many brands, so with the bearing part number (or bearing in hand) it should be dead easy to find local suppliers of suitable replacements.
