    It is available now a new 4 stroke, twin boxer, EFI, engine, 42HP at 6000 rpm, based in the strong citroen 2CV6. This kind of engines are used in Europe (look for PIK-26, ULF-2)

    Can be seen at SAVOIA CARS Autopartes - Autopartes y conjuntos nuevos para mecanica Citroen 2CV y 3CV

    Regards

    Hmmm. 110 lbs and 1.76gph at 80% compared to 80 lbs and 3.5gph for a 2-stroke. Total weight the same with a 5 gallon tank for the 4-stroke vs a 10 gallon tank for the 2-stroke, and equal range. Seems to make sense on anything but an ultralight that's hard up against the 254# limit.

    I wonder what it costs?

    I don't like the idea of term limits for politicians. I think they should get the same sentence as all other criminals.
