Swingarm - How to tighten is in the second link that i posted.
Triple trees, sleeve nut and what not - have you installed new steering head bearings? If so the technique is to tighten the nut until it is too tight - until the steering will not easily flop back and forth. Then loosen it until it will just flop from center to either side with a gentle push.
Over tightening to start with is to ensure that the bearings are fully seated. Some guys use an 8" criteria - that is it will not flop over unless pushed from 4" off center. Be sure to re-check this after a few rides.

Yes i am familiar with that and it is what i have done. I used a fish weigh scale that i bought from a sporting goods store.
Read thru the second link that i posted in #2 above. You will find there some opinions that this weigh scale thing may not be necessary. The guys posting there are all knowledgeable, have had these bikes since the 70s, have their own shop, and are highly respected. Hopper, fergerburger, EricFreeman, MoonWolf, perhaps others.
