Hello Nortones7,
Have you actually removed the yoke from the steering head?, and ended up with the top bearing coming out of the steering head, still firmly attached to the yoke stem?, if so then the inner spacing tube should just fall away, its a very loose fit, or was on mine, if yours is on tightly, perhaps you can use something to hold onto the spacer tube, and turn it until its lose, work it one way, then the other, if its corroded onto the stem, some penetrating fluid would help, moving the spacer tube towards the bottom of the stem.
If you have the yoke out of the head, then you might be able to prise the bearing off the stem, working it down towards the threaded end, using something like a large flat headed screwdriver, but its difficult to get a purchase with out damaging the top chrome cover, the correct way would be to use a special bearing puller, like this one, http://www.amazon.co.uk/TecTake-BEARING ... ing+puller
Perhaps not this actual one, looks to be very cheap!, maybe, if you do not have one, you could pop the yoke along to an engineering shop, or dealers, and get them to pull the bearing off?.
The stem itself comes out from the bottom, the threaded part goes in first as there is a circlip/snap ring which sits in a groove at the top of the stem, stops the stem from being pulled through the top yoke, here is a good photo of the stem showing the groove, just above the knurled part, http://www.rgmnorton.co.uk/csi/1245184/ ... 3925125944
So, the stem is pushed out of the yoke from the bottom threaded end, its only knurled for the length that actually fits into the yoke, the rest of the stem will then simply slide through the yoke.
I have just replaced the stem on my Interstate, see my thread here, worn-fork-yoke-stem-t21689.html
If the yoke is still stuck in the steering head, you knock it out from the bottom, but it sounds like you already have the yoke removed.
Hope this helps,
John

Fork tubes removed, Straighten the tab on the washer holding the bottom nut and remove the nut
Hold the Head lamp and tap of the bottom yoke with a soft mallet be careful not to damage it. There are O rings on the yoke where the headlamp tube fit, probably best to replace them.
Drive the stem and yoke up and out with a soft mallet
Insert a drift through the top bearing and move the tube to the side and carefully drive the bottom bearing out with the drift on the inner race of the bearing
insert the drift from the bottom and with the drift against the inner race drive the top bearing out.
This is directly from my Clymer manual and it is exactly how I rebuilt mine. works and rides great. The bearings are cheap so I put new ones
