This could work, but almost anything will do. The fit doesn't really matter since most of them come with enough tubing to reach into the engine. I have a fluid filled 4-bank from when I had to tune carbs on my XJ-650 Seca, but you can block off the meters you don't need.
I recommend fluid over needle gauges as they tend to be smoother. Not as cheap unless you build it yourself. There are plenty of tutorials online, but you will have the chance of sucking it into the engine if you mess up.
Thanks guys. The Carbtune looks like a nice kit. Is there a U.S. distributor? I also looked at some of the DIY apparatuses people have come up with. Seems simple enough for what I need. This guy has one that can't suck water into tubes. http://youtu.be/Y_WDF6glD5k Maybe I'll give it a try.
Thinking into it brings up another question. The service manual states to use an external tachometer. Is there an easy access to a tach signal if you don't have one with an inductive pick up.
I bought the Morgan Carbtune many years ago and it is very high quality kit. Bought online and it was shipped to Canada in a matter of a few days. I have bought other kit from Britain and I am always impressed how quickly they get products to me. Faster than Canada Post to Vancouver from Ontario!
Here is how I synced my throttle bodies just after I bought the Versys.
A Homemade DIY manometer - just a loop of PVC tube filled with 2-Stroke oil (as it coloured blue).
I needed a digital multimeter so bought one with a RPM inductive pickup to set the RPM correctly.
I have the same tubing-on-wood setup. If you do this, just fill it with oil or ATF fluid or something. Dont do water, as there is a chance that you will suck whatever is in the tube into the engine. Oil and ATF will make the bike smoke for a bit but wont do any damage. Water might.
