CA wants to smog check motorcycles

[pdog]

I don't know the units, timespan, location or any other background or context about the numbers in your chart. So I can't agree or disagree with any conclusions about the chart.

I applaud cleanup of other sources too. Motorcycles shouldn't be unfairly targeted or exempted, more than any other emission source.

You understand that transportation only has a 7% impact on Particulate Matter - which actually has more of an affect on asthma and smog than VOC's. That is OVERALL pollution. And, motorcycles don't come into play there. [referring to the chart] My 7% number comes from my research project and text book used for my class.

Did you notice on their report that lawn and garden equipment actually had a higher output of CO than on-road motorcycles? So, those should have converters too...

I'm late, and didn't read the whole thing, but I think the complain with MC's is that while they might emit less/vehicle, they tend to emit a lot compared to engine size, and passenger count.

Toss in the rampant changing to off-road exhaust systems, and you have a big basket of low hanging fruit.

Even if the total emission output of MC's isn't a large portion of the total emission output.

Well said.
