It was a new episode last night, so likely not available elsewhere, yet.

The bikes were progressively cleaner by date - the 80's bike was the worst. The new 2010 Yamaha 250 was the cleanest bike, and proportionally cleaner with the aero fairing. That's good news. I believe it is fuel injected. Still no catalytic converter I believe, so that's where the emissions came from.

Not sure if it was by total emissions or by percent. Still, even if it was by percent it comes out as worse. At maybe 1/2 the car's fuel consumption but 5x (by percent) the emissions, that's still 2.5x total output. If it was total, that's WAY worse.
