Here in Phoenix we have to have emissions done every 2 years on vehicals older than 4 years. Well this year is the first for my SG. I didn't think I would pass first time through. I changed spark plugs, added 1 quart of denatured alcohol to a tank of gas and walaa, the bike passed. Hydrocarbons @1514, standard being 1800, and Carbon Monoxide @4.78%, standard being 5.5%. It is such a joke with this emmisions, cost 19.00 and took 5 minutes.

Maybe Zippers will do a ThunderMax upgrade with a selectable setting, "Emissions Test" that includes a hotwire in the O2 sensors to nuke any unburned hydrocarbons...

Had mine done just before I traded it in. Money grab for sure.

Soon as I get some cash I want to upgrade to the Auto tune.

must be nice.... here in Japan emissions are standards are tighter than Cali emission laws and can cost over 2k to have done.

When I worked in Phoenix (quite a few years ago).....I can't remember not getting any bike to pass emissions. We had our tricks though.

HC below 1800parts and CO below 5.5 is actually very do-able with almost any size fuel injected engine in the range they're tested. Typical cruise range CO would be in the 2.5 area.....HC gets a little heavy with the bigger cams.
