I believe they're there for tuning access, for fuel sniffers to analyze the air to fuel ratio. It gives a better read than at the exhaust tip, especially with the crossover pipe.
I am especially interested in making my own sniffer for each of these bung fittings. With our cross-over tube, a reading cannot be made for the individual carb's air/fuel ratio. If however a reading is taken prior to the cross-over, you get a reading of each individual carb'.
I'll be willing to bet that a good Triumph shop already has such a tool, but it should be pretty easy to make one.
I want each of my carb's sniffed individually.....

I've had my bike dyno'd several times, each time that sniffer was so far up the exhaust I thought she was gonna gag on it.
lol...I hear ya! I've often wondered about the bolts also and I've searched for an a/f meter with probes that may fit. Nada, I haven't seen one yet, the all use a bigass o2 sensor. I have seen egt meters that may fit the job though.
I also gave some thought to putting a temp probe for an egt guage. pegasus has a nice dual reading guage for about 100 bucks, then you'd need 2 probes at 50 bucks each, so about 2 bills give or take. I dont think you'd want a permanant installation, it burns the probes up.
but you could set the carbs at full throttle by it, should be a good way to set mixture
