Bikes have catalytic converters?
And the officers and state flunkies who would enforce this nonsense would know which ones do and which ones don't?
I underwent a visual inspection (surprise!) for emissions on my MGB two years ago - '72, pre-cat. I was worried because I've installed a supercharger, and figured I'd get pinched for removing the smog pump. It's my best guess that ALL THREE HEADSCRATCHING INSPECTORS mistook the supercharger for the pump. They weren't admitting their ignorance or admiring my work - they were trying to make heads or tails of a car they didn't have any working knowledge of.
I almost soiled myself. After attempting to set the front wheels on the rollers for the simulation, and thus discovering that the car was rear wheel drive, the smog jockey rolled good numbers on the dyno, and passed my car with 221.4 HC on a 550.0 limit and 2.76 CO on a 7.0 limit.
Fortunately, due to cutbacks, new Wisconsin emissions tests only check ECU, and only on cars '96 and newer, so hopefully I'll not have to tempt fate again.
