    Sirs: Could you please tell me what is the size of the piston pin in a Polini Big Evolution 84cc kit.
    My current set-up has a 12mm gudgeon pin and wanted to see if the Polini Big Evolution
    kit would be a match on the pin size.

    Hi a while ago I purchased a Polini cp23 off you guys and was wondering what the correct filter for this is as its going on a two stroke Yamaha FS1.

    Any info would be greatly appreciated.

    Thanks David
