I've been involved with small displacement transportation for a while and I'm looking to start producing a cost effective form of transporation but i'm running into some issues with U.S. regulations. Are there currently any 49cc 4 stroke engines that meet the EPA's Class 1 standards? I've found that the GX50 model meets phase 3 standards which is 10g/kw-h and the standards for bikes is 1g/km for new manufactured motorcycles. I'm trying to see if this would work or if I need to keep looking for an on road emissions compliant engine.
