Stage 6/mxs minarelli vertical +2.5mm stroker Kit
Head + crank combo converts your Stage 6 or MXS Minarelli vertical motorized bicycle engine Hybrid into a 42mm stroke monster. Factory timing is a little too aggressive at 190-126 when running 39.5 or 40mm stroke. This kit fixes that by changing the timing to 183-120. This timing change plus increased displacement results in more power everywhere with an emphasis on the bottom end performance.
RDM billet head designed for a 47mm Scooter piston with a +1mm combustion chamber and .5mm gasket
RDM standard Racing Stroker crank 42mm stroke 10mm needle bearings.
kit will not require any machining or spacers to work. Although the added stroke brings the piston 1mm lower this is canceled out since the rod is 1mm longer. The addition 2mm stroke above the ports is accommodated by the heads combustion chamber being set to the correct height.
