    Benelli 125 Sport Special piston clearance

    Hi all. I'm new to here. I'm rebuilding a 125 SS 4 stroke egg motor and in the process of getting it rebored. Does anyone have the piston clearances for this engine please?


    Well clearly no one here knows. I guess its all about Tornado's.
    I have since found the answer so thought I would post it here in case someone else in the future needs this.
    between 0.03 mm - 0.05mm (0.0012 '' - 0.0020'') clearance between piston & cylinder. This clearance should be measured at 90 degrees to the gudgeon pin at the bottom of the piston skirt.
