After spending a good portion of my day off at the California Inspection & Maintenance Review Committee meeting, along with 4 other representatives of the motorcycling community, I too would like to know where she got her numbers. (this was a meeting concerning, among other things, smog checks for motorcycles).
In a google search of various articles I found that she probably got her info from this site
https://www.arb.ca.gov/msprog/motcycle/ONRDMC.HTM
But as you can see if you go to the site, the last time it was updated was over four years ago. That and she quotes a representative from CARB. That would be like a spokesman from the tobacco industry telling us smoking is ok and using their data and research.
But this link, a report from 2003, tells us that no one from the EPA or CARB have done anything about motorcycle emissions from 1980-2004. 24 years without any requirements on manufactures to produce cleaner bikes than the 1980 standards. So, of course you are going to have a lot of "dirty" bikes out there that were produced those years.

This site might be considered bias by the media, but this link states that California motorcycles...

"Motorcycle emission standards were first established in 1978 by the EPA and have remained unchanged since the 1980 model year. Those standards are 5 grams per kilometer hydrocarbon and 12 grams per kilometer carbon monoxide (5 g/km HC and 12 g/km CO). Only one state, California, received permission from the EPA to set its own lower standard because of its unique smog problems and, in several stages, reduced its motorcycle emission standard to 1.0 g/km for 50-699cc and 1,4 g/km for 700cc and above motorcycles. The current California emissions standard is therefore 3 1/2 to 5 times cleaner than the Federal one.
Additionally, in 1998, the California Air Resources Board (CARB) passed new standards that will further impact motorcycles after 2004. New motorcycles over 280cc, sold in Calif., after 2004 must certify to no more than 1.4 g/km HC PLUS oxides of nitrogen (Nox), and after 2008, must meet a 0.8 g/km HC + Nox standard."
Nice little chart showing how much cleaner motorcycles are regulated to now.

So if you take into account all the info in the links, we can probably look to the 2003 FJR's as the problem,
and not the 2004 or later FJR's.
