Just sayin' and not meaning to start a thing but a Honda or HS 50cc has far more power then stock 70cc 2 smokers. I am told the 50cc 2 stroke morini engines would eat either of those in a NY minute. Just saying. Truth be told, I much prefer the way my 2 bangers look but enjoy the feel and performance of my 4 banger. I only mention this because it seems common that folks think the 4s are less powerful and slower. The reverse is true. All stock and not pertaining to the really high end motors.
