Finally got to it last weekend. Got .85 springs and US1 oil from Race Tech. Preparations were a PITA, but the change is relatively simple. I initially thought about doing the gold valve while I'm there but figured it would be simpler anyway to learn a little about the forks before tackling everything at once and focused on springs and oil alone.
The video was okay, but really the 4V Haynes should be used for this job. I initially thought I could do it alone, but eventually had a friend help with holding the spring compressor. I suppose it's possible to do this alone, with the right vise and experience, but it's tricky. I was surprised to find one fork with the correct ordering of spacer, shims and spring, vs. the other with spring, spacer, shims. Also found a piece of plastic, but all seals appeared undamaged, don't know where it came from. The fork is almost new, but has been sitting for a while and the old oil was pretty dark, glad I changed it.
I did tape the cap but still scratched it a bit, nothing serious. Other little **** ups, I didn't verify that the rebound adjusters sit at the same height before putting the caps back, so may have to reopen. Current settings are not at the extremes (got the right spring) so I'm not in a hurry. Also forgot to align the axle passage to the compression adjuster.
I've looked around for tools and found complete kits from Traxxion. The Race Tech spring compressor may be suitable for working alone, but it's a $100 more. The tools from Traxxion are easy to buy and are affordable.
To lift the bike I used a rear Pit Bull with the New Front conversion. I'm very impressed with the quality of this construct.
I can't really do a comparison, since I took off the stock non-adj. Showas which needed new oil badly. But from a few days of commuting, the damping is a lot better and there's less dive. (Also put a 2-way Penske).
