We do dyno runs for emissions here.
It's only money...
... mine 
Dyno runs.....

Look at the screen next time they "dyno" your car......
Ohio does EPA testing also, has for decades... they let you pull in, and drive tires sit on a rolling drum, but it ain't a dyno... they test fuel filler cap on a tester for leakage, run the plugin diagnoscs on the ECU, check milage, run the vehicle up to and hold 35 mph on the "dyno".. its just a speedo thing... and check system...
If you have dash lights saying service engine, they can refuse the testing, but if you are smart, and have issues with dash lights, you can stop at Autozone, use their code reader, and go in and erase all the stored error codes on the way to the test station... then you can sign a form, and submit to a sniffer test....run at speed.
My 98 gmc sonoma, with check engine light, once cleared, aces the emissions every single time I've had it inspected, all emissions are below 10% of the range they check as minimum... so its a cleaner engine than most on the road... then I get a clean bill of health for 2 years before needing another test...
They will NEVER do testing on bikes here, and in Va., the only inspection they do is for burned out bulbs, horn, and a visualnwalknaround... never see them doing emissions in future either for any vehical, as they won't spend the money to setup all the inspection stations which are mostly garages doing brake, tire, and minimal autonservices...
I still don't understand the emissions thing, hell, with all the dieselntrucks and busses, I see everyday belching black smoke, I have to think its a bad joke...
