Ok, in the spirit of the recent "build your own" threads, I thought I'd pass this along. This is a manometer, it uses the low pressure in your intake tract so you can accurately synchronize your carbs. It isn't necessary for the Vmax-4but works awesome for newer sleds like the RX-1.
Credit for this design goes to a buddy over from TY, so if you want to build one PM me and I can fill you in on the little details.
Basically it starts with 1/4" ID hose filled with ATF and steps down to 1/8" ID to fit the nipples on the carbs (RX-1). The line must be restricted to keep the fluid from bouncing (high dollar manometers are filled with mercury which is heavy) but the lighter fluid allows this meter to be more responsive for finer tuning.
Here's what it looks like...
