I've been in correspondence with Devrou(Sean from BikeMotorKit.com) on eBay. His listing for the GT4 Starfires went up in price yesterday and he attributed it to running out of stock. I asked him if he'll be getting anymore in and he said "No, they will never be allowed back in the states since the new EPA laws changed." Does anyone know anything about this? I guess my question is, has Big Brother banned these little motors?
