Andy B Posted May 10, 2023 Report Share Posted May 10, 2023 Hi Folks, I have a 156cc and the piston code is 'E', it appears a little worn and I doubt it's the original. The bore is good and not showing much wear and I've spent a while carefully measuring it's diameter with about twenty or more reference points. I'm thinking I will invest in a new piston but can't find any information on the sizes relating to the codes. I did ask a dealer and they came back with they only have the codes on the pistons not sizes. I would rather just order a piston to match the bore size than keep buying them one by one until I find one with the correct clearance! Any help would be greatly appreciated. Thanks.
