    I don't see how that could be true.

    Flat out liar or a fool?
    Dishonest sellers have been claiming 5 + HP for a long time.

    Stock 66 cc China girls make about 2 1/2 hp
    Socal Motor Bicycle Racing has dynoed China girls from stock to 9 + hp at the races.

    The Arrow Motorized Cycles Street Racer honestly claims 4.5 hp.

    Zero, absolutely zero chance of a 66cc Chinese 2-stroke bicycle engine making in excess of 5hp out of the box.

    People spend about half their life savings trying to get more than 5hp out of these engines.

    maybe shetland power. 3 hp is pretty much the barrier with these engines, you'll never make more without major modifications that are too expensive to do in mass production. unless it's ported and balanced I don't see it happening.

    i think james watt originally calculated the hp from welsh ponies, as used in tin mines, but greatly exaggerated the figure himself for, you guessed it! better sales :jester:

    erm, cus of the typo here, im saying its the complete truth, if not understated...5/6(ths) of a hp :)



    hmmm, 125-150mpg...

    erm...thats about 200km for 5 litres, cus i still say gallons are 5L though for some reason americans dont...

    so thats 40 km/l and yup. thats pretty spot on ;) pretty lousy when you think a v8 can do better than that, lugging around a few thousand kg...

    imperial gallons (english measure) are about 5 liters,... U.S. gallon is about 4 liters

    I'm skeptiical. I wouldn't expect that engine to hold together very long if it, in fact, produced 5 hp.
    That is Moto Morini territory.
