Nicely streamlined and detailed.,.,.,great job. As for info on sticker requirements.,.,.it may vary from state to state but generally are mandated, and that any company producing an engine which creates emissions are operated on city or state highways are required to post on every unit sold the year of production, type of fuel, size 50cc, etc. It also covers information which is required to meet the U.S.E.P.A Regulations. I've seen them posted on the engine (unit), and generally are not posted at any other location. Although not the norm, it's posted and clearly visible,.,..,.peace, Stuk
