The standard psi (using the Suzuki tester) is around 140.
The fact that they are all close would lend towards being ok and your tester reading low, id check again and if the same you could add a very small amount of oil to see if this gives a better reading due to sealing the rings.

There's a good chance that if its smoking the carbs need a rebuild, if you got a temp gauge check its not reading low due to a rich mixture.
