Since throttle position is what you need to look at when tuning your carbs, I made a little pointer for my throttle from a piece of plastic and a sharpie for the scale. Simple, cheap and effective.
Analog TPS. My favorite and I may just go back to that after screwing with software calibration and 5v sensors.
Not FI. Carbs. No TPS, so I modded a GSXR600 throttle servo TPS to fit on the oil pump. That is tied to an Aux Box along with MAP, RPM and CHT inputs. It's connected to a Ultra wide band O2 sensor and small 32 channel datalogger.
I want to be able to see what the F:A ratio is doing at different combinations of throttle and revs. Because they are CV carbs, I'm hoping to see the correlation between MAP, alpha, and n. May just turn out to be a complete waste of time but it's fun so far. If only it would warm up so I can ride the thing.
If that's successful, I'll use it with the Jemcos and 32mm round slides and I have a set of BST36s from a GSXR which should flow way more air that stock BS40s and they look almost stock so that might be a nice 2014 season upgrade.
I started off with sets of GSXR600 and R1 throttle bodies and stopped that when I worked out that I need secondary injectors to get enough pulse width without exceeding 100% duty cycles. Larger single injectors work out in theory at least to extremely short duty cycles. That's when I decided that if Bimota can't do it on a 500 twin, how TF and I going to do it on a 750 triple.
If I live long enough anything is possible. I may have to build something for SE Prostreet one of these days.

You are doing this on a H2? Yer da man! I didn't think you could even run CV carbs on a 2 stroke! Do you have a thread related to this that I can subscribe to?

Cool tool! I don't have jam nuts on my carbs but I certainly can see if I did, that would be the tool to make.
A buddy of mine made a custom screwdriver for his air screw adjustment... He fashioned it from a welding rod, peened on one end to fit the slot perfectly, long enough that it could reach all the carbs easily from one side, plus bent at the end to clip on the frame under the seat of the bike unseen... Perfect for making the adjustment while you are out on the road.

My homemade spring compressor. Saw it somewhere else and was easy to make. Large C-clamp, small cut piece of wood and a magnet. Worked like a charm.
