    It's got a 47mm cylinder, matching cylinder head and piston.


    and this:


    combined with a reed valve intake:



    Could make for an interesting combination with a balanced crankshaft and decent bearings to safely liberate a few more rpm.

    Not too sure.
    I think what we would need to know=

    Bolt Pattern dimensions
    And the distance the piston travels.

    The Stroke Distance would be very important.

    As far as the first two links go I'd have to say NO.. Look at the base gaskets...the gasket that goes between the cylinder and crankcase.

    I actually think for the cost.
    It would be better to redesign the jug for high performance.
    READ THE 2-STROKE tuners handbook.
    And have it machined.
    Then you know it will fit and work with our motors.

    For some reason i heard reed valves wouldn't work with our motors.
    I think because of the porting in the engine block.
