First, very nice job.
When I did my carbs in August I purchased the Randakk's kit. I ended up also buying the Saber Cyles kit later because (1) I managed to lose a idle fuel jet (blew it out of my fingers blowing air through the cleaned jet) (2) The slide needles on the 1 and 3 carbs were not in good shape and (3) I had a heck of a time pulling the float needle seats, doing varying degrees of damage to all of them.
The idle fuel jet is really hard to find, and 4 carb kits cost about the same as 2 stock Honda float valve sets, so I figured I would take the chance.
However, as Randakk tries to tell you in his video, the Honda parts are worth the money. The idle fuel jet turned out to be slightly too large for the tower. It got stuck and I had to drill it out. I measured the slide needles that came with the kits, and as Randakk says and your pic's show, they were clearly not the same size.
I finally located a full rack of '77 carbs on eBay for $89 and scavenged what I needed, including the entire #1 carb and all 4 float seats, although they still sustained some damage during removal. I will be ordering a full set of Honda float seats during the winter and swapping them in before next riding season.
Overall I would say that, at least on the GL1000's, the Saber Cycle kits are very much not worth it and Saber Cycles can maintain to their dying day that the kit is the right one for the 764A carb, and they will be wrong. On the plus side, I was able to drill out the primary jets they supplied for Randakk's "off idle hesitation" fix, which saved me the hassle of soldering and drilling.
