I'm not Jeremy, but here's my two cents worth. The manual calls for a very specific 'ring nut wrench'. It will even list a part number for it. It probably says to tighten to a specific torque, then loosen and then tighten to a light torque. Pretty much the same as how I usually do wheel bearings, except you need this funky wrench to grab hold of the ring nut. The wrench looks like a small spanner wrench with a 3/8th drive adaptor for a torque wrench.
When faced with the same situation as yourself, I decided to just order the wrench to get it right. Well, the shop can't order the wrench because tools don't show up on their computer. I've looked around the net for this ring nut wrench and haven't found one yet. So therefore, I haven't regreased the streering head bearings yet.
I did do all the re-greasing for a new bike - swingarm bearings and pivots and both axles/bearings, shock, and to my surprise all had plenty of gease, but this is not the usual case.
Some people have suggested to just use a punch and hammer to set the ring nut, but I dont like that idea. How did you get the ring nut off in the first place? How much grease was on the bearings?
Sorry for the long and generally useless response, perhaps some will find merit in it. Please report how you solve it, I'd sure like to know.
