Carbonda fork vibration
carbonazza:
You also need to check the space between the top of the steering tube and the plug. Sometimes the tube is cut too long, which makes it contact the plug, preventing proper compression.
Keep tightening the plug gradually. Place the bike on the ground, pull the front brake, and place your thumb and index finger in front and back of the frame where the headset contacts. Then, push/pull the bike to feel for any play. Tighten the plug just enough so you don't feel any play, but not too much more than that.

Thanks for the suggestions. I tightened it last night and will give it a test ride this weekend.
PLA:
perhaps a rotor with some warping. i've had this before.

I had the same problem with my Carbonda 696. I checked the fork just now, but there was no play in the bottom bearing area. BUT: then I noticed there was play in the upper bearing area.
I tried upping the preload with the top cap bolt, but could not get it tight enough. It looks like the expander was the problem. The spikes on the surface of the expander seem to have become dull, so there was not enough grip and I just pulled the expander up instead of increasing the preload.
I had another expander, put that in the fork tube et voila. I can not get enough preload to stop the movement.

I moved to the 50mm long Origin8 alloy compression plug and it solved the slipping issues on my 696 fork
