I went to the Arizona Department of Environmental Quality (ADEQ) website .
Someone there actually realized after a lengthy study, that motorcycles only contributed .04 % of exhaust emissions in the two counties that had the requirement to have the tests done, as part of the yearly vehicle registration .
It wasn't worth the time effort and expense to continue the testing .
Looks like I'll start working on the Guzzi sooner, the bike was next to impossible to get through emissions testing, according to the previous owner, that was the main reason he parked the bike .
So I wasn't going to get serious about working on it, until it was getting close to being 25 years old, then it would be eligible for historic vehicle plates, that and collector insurance, would negate the requirement for emissions testing .
