look motoritec,naraku, dr etc. cast iron cylinder, you will find them in less than 70 eur for example ebay. These also work well for standard carburetor and exhaust pipe. my opinion is: cast iron cylinder and two piston ring to provide a long service life ,max 10000rpm then it takes even if the standard crankshaft...honda dio af16/18/27 parts fit to kymco.
