As before, motorcycles and other motor vehicles without such emission control devices are not required to be equipped with gasoline tank filler inlet restrictors. The Clean Air Act and corresponding EPA regulations prohibit gasoline containing lead or lead additives (leaded gasoline) as a motor vehicle fuel after December 31, 1995. As a deterrent to misfueling prior to that date, the EPA regulations required filler inlet restrictors on motor vehicles equipped with an emission control device that could be affected by the use of leaded gasoline, such as a catalytic converter. EPA retained that provision after 1995 because the filler inlet restrictor, besides being a deterrent to misfueling, has also been incorporated into the design of some vapor recovery gasoline nozzle spouts. Gasoline tank filler inlet restrictors do not work well with most motorcycle fuel tanks, especially the saddle type of tank, because of their shallow depth. A gasoline tank filler inlet restrictor may cause gasoline
