Finally a kit designed specifically for the CPI SM –SX 50cc
geared engine (AM6 clone), the Airsal Tech 80cc high end cylinder. Many
companies have listed AM6 cylinder kits to fit this bike for a long time
however they are not a true fit and always required some kind of modification
like changing the exhaust etc. This kit is 100% designed and developed for the
CPI engine making fitment a breeze on the original or any after market exhaust systems.
It offers big performance gains thanks to the capacity increase to 80cc
and completely revised port layout. Supplied complete with everything needed to fit however you will need to
increase the main jet size in your carburettor and change the spark plug to a
NGK BR8ES.
