Miscellaneous comments (these relate to my K6 1000 but I'd think would also apply to yours):
The multichannel vacuum gauge that Suzuki shows is the Kowa Seiki KEK-55-64. It's nice but expensive ($600+). Even the 09913-13121 vacuum balancer gauge, now discontinued, was $200+. Used ones appear on ebay from time to time. AFAIK
the Silmar 317400 is a copy of the balancer gauge, but it's difficult to find outside of South America. I assume that you'll be using manometers, multiple dial vacuum gauges, or the Motion Pro gauge. I put together a digital gauge from parts that I already happened to have. It works fine but to build it from newly purchased parts would have cost more than the Kowa Seiki.
Some ebay silicone tubing made things easier because it's so flexible. I found it difficult to get the OEM vacuum hose off of the throttle body nipples and much easier to connect to the vacuum hoses where they tee together.
I made a lighted switch plus indicator light that I plug into the fan relay socket so that I can turn the fan on manually. This allows me to operate for extended periods without overheating. Instead it warms up to 175į F and sits there.
I found the adjustment screws hard to reach so I made a custom screwdriver of the right length and diameter, 5Ĺ" x 6 mm round, to more easily engage the screws. Numbering the flutes on the handle made it easier to keep track of how many turns I was making.
