Ok, very new here! Have had a 1968 850 Spider sitting in the garage for over 25 years now. And after 4 kids and a lifetime of stuff to do it's time to get to this one. I need to clean up the dash wiring from the previous owner, a new dash pad and rebuild the engine and it will be a beaut. My issue with the 817cc motor, it was bored .6mm over and now will need to go to 65mm. I can't find any references for pistons for the 817. Does anyone know if the 65mm pistons from the 843 will work in the 817? Or do I need to sleeve it and start over? I would like to keep the 817 in it. Any help would be appreciated. Thanks
