carbon fork : expander plug install question
I try not to ask fredly questions, but I need some reassurance. I just installed a full carbon fork + FSA expander plug, but am still experiencing a rattle from the fork between the spacers.
Just so I have my install procedure correctly..
1) cut steerer
2) install crown race
3) install fork into frame
4) add spacers
5) hand tighten stem
6_ insert expander plug, torque inside bolt
7) add 5mm spacer
8) install top cap, torque
9) tighten stem
I then did more research and Specialized instructions specifically says that the there should not be a spacer between stem and top cap, but from the looks of it, the diameter of the topcap is smaller than the inside diameter of the stem (i.e., they wouldn't make contact).
thoughts?

Also, when you've tightened the top cap, before you tighten the stem bolts, put on the front brake, and roll the bike forward, until the rear wheel lifts off the ground.
If there's a clunk, the headset is too loose. Conversely if the steering binds, its too tight.

Very good advice guys, thanks!
So let's say I wanted to remove the spacer above the stem, there is about 2mm gap from the top of the steerer to the top of the stem (the stem is higher). Is this the way it should be?

If the bottom of the cap is convex, that might not be enough room to where it won't hit the steerer tube.
