Returning Visitors
If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.
If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

According to the manual, yes.
According to some of us who didn't know any better before reading the manual, no.
Why should they be higher? Everybody has guessed, but nobody has come up with a definitive answer.
The only definitive item that I can offer is "how much". I borrowed an official Suzuki gauge some time ago (have since gotten one of my own :encouragement
for some experimentation. I used my Mercury sticks to get all the vacuum levels lined up PERFECTLY. I then connected the Suzuki ball gauge and adjusted it so that all the balls lined up perfectly, as well. (That Suzuki gauge is a FIDDLY beast.) I then adjusted #1 and #4 carbs so they were the prescribed half a ball higher. Took off the Suzuki gauge and re-connected my Mercury sticks and found that "half a ball" is 2cm of Mercury.
Why the difference? Nobody really knows, but the guesses are interesting. Some are saying that feeding more fuel to the inner cylinders (lower vacuum is because the throttles are opened just a little more) will let them run cooler, but it's actually adding more of the proper mixture, not a richer mixture, so I think it would run hotter. Some will say it's because they are CV-type carbs. Why would that matter? It also happened to co-incide with the appearance of the balance tube between cylinders 2 and 3, so some say it makes up for that? What's to "make up"? On top of all that, the general wisdom is that if you have stock pipes, run the outer cylinders with a higher vacuum, but if you have a 4-into-1 header, run them all the same. Why???
In spite of what the book says, I still run them all the same.

I think its because the air box 2 and 3 are straight with the air filter air has to go around to 1and 4 so a little help by adjusting them higher by mine all stock
