    might be buying a 70cc hebo manston replica kit,
    just wondering weather you can buy replacing piston and rings or just rings on there own for this kit if not would any 70cc piston fit etc might sound like a dumb question but not sure

    yea find the 70 kit on scooter attack then look at related products it should have all the individual parts.

    ive always wonderd weather you could use a single ring piston in something that had a 2 ring, for eg. an evo piston in a polini sport? what would be the effects?

    No dont use different brand pistons in different cylinders. Not a good idea, trust me lol either buy a piston kit, or find a yamaha or makita dealer who do replacement pistons an ask them for the size u want

    aslong as the piston is the same size and for the same fitment you can prittymuch use any piston in any kit.. as stated it needs to be the same diameter (verry close tollerance on this) some kits the piston crown and port latyout is slightly higher altho this is rare so a carefull squish test is always best when experimenting. single ring in an mhr rep means you can open the transfers out and prittymuch lay an evo 2 port map over the top ;)
