All,
I found a very useful site on the web; The California
Bureau of Automotive Repair (BAR) at http://smogcheck.ca.gov/
(these are the guys who DONT want Gov. Wilson to sign SB42 into law).
Specifically, I direct you to the page at http://smogcheck.ca.gov/000019.htm
which has links to the emissions standards for the current (BAR-90)
requirements and post Dec 1, 1997 (BAR-97) requirements.
I may need some help in interpreting the tables for BAR-97, but it seems
to me that the test includes two "pulls" on the dyno, labelled
ASM 5015 and ASM 2525 (ASM = Acceleration Simulation Mode). The
resulting emissions are combined into a formula that include the vehicles
test weight. I attach the tables for 1971-1974 cars below. Note that
there are two rows, A and B, such that the results of your tests
plus the columns of B divided by the test weight should be less than
the columns in A; ie
A + B/VTW where where VTW = Vehicle Test Weight
Tricky? Take a moment to feel sorry for the poor guys having to
buy all this equipment and install it before the Dec 1 deadline.
I am not sure if this is the complete requirements of SMOG II, as the
new equipment includes a 5-gas analyzer, so will be requirements on O2
and CO2 which are not listed in the table.
The new equipment also includes a "gas tank cap sniffer". Replace the seals
around your gas cap, folks!
For completeness, I include the standards for the current test
at the end (1971-1974 cars only).
Am I interpreting the BAR-97 tables correctly? Please tell me and
others if I am wrong!

Emission standards used to determine if a vehicle passes the
emissions portion of the inspection -- a vehicle passes if the emission
levels are equal to or less than the standards for HC, CO, and/or
NOx for ASM 5015 and ASM 2525.
