anyone know a piston kit maker /manufacturer??

Can`t give a definate price yet Dave but to replace a malossi kit on a 52mm (std) stroke crank it`ll be a smidge cheaper than a new kit but with the advantages of a top quality piston,bigger bore (66mm), better port timings and the future life of at least two re-bores so no re-plating or scrap barrel if the worst happens.
