There are plenty of threads on here for synching carbs. No pictures here but I can tell you how to do it:
Install front cylinder vacuum adapter after removing grub screw unless already equipped.
Cut vacuum line under tank and install T fitting.
Attach carb synch tool to T fitting and front cylinder vacuum fitting.
Start engine-idle 2000 rpm, engine warm, choke off.
Adjust synch at synch screw.
Done.
If you use the search feature you can find all the instructions, some with pictures and even the shop manual on here that will get you through this.
EDIT-Don't forget to plug vacuum fittings when you're done.

I followed the procedure in the shop manual the first time I sync'd the carburettors in order to keep the vacuum line as pristine as Honda intended it to be. Doing so was a mistake. Getting the line back on the fitting on the rear cylinder took many attempts over an extraordinarily long period of time. Cut the line as RWhisen suggested.

Anybody got a line on a refill of mercury for their sync sticks? I have had the same motionpro sync tool for probably 15 years now, and I went to sync my carbs on the VTR and my Dad's FJR a few weeks back before my trip, and I swear I think I'm worse off now than before I did it. I tapped the base of the unit a bunch to try and settle the bubbles out, but the fact remains that the supply is low (it's fun loaning out tools and getting them back not quite as nice as when you sent them out) I got the FJR spot on, but would really like to add a few more ounces before trying the VTR again. Doesn't look like motion pro uses mercury anymore and I have heard that the blue fluid is garbage and bubbles in the column too much. I guess my other option is gauges, but I worry the needles would jump too much.
What are others doing these days?

I had the same issue.. and did not find an easy source for replacement Mercury. Motion pro no longer sells that type at all.
So I bought a new Motion pro sync set up... I've used it on a dozen bikes in the last 7 months .
No issues at all with the new fluid MP is using.

I use one of the CarbTune synch tools. Works great and the whole process is less than five minutes.

For the front cylinder there is a little bolt, on the 49 state model, you're supposed to remove and reinsert each time you want to synch. I just went to the Honda dealer and looked on the microfiche (diagram) and found that the California model has a nipple that screws in there for some kinda hose. I ordered this nipple, installed it permanently, ran a piece of vacum line between the cylinders, put a spring clamp on the nipple and a coupling with a cap on the end. Takes 5 min to synch, not even kidding!! You even got lucky I was takin pics of somethin else so here you go.
