16mm Gudgeon Pin, will need longer rod and boost window cutting in. Both ring pegs are directly opposite (at 180 deg to) the exhaust port. Prices will be for a set of 3, you can get them individually on ebay and the like

16mm pin, standard 39mm compression height, dunno about rings but they do the same piston for thge RB250 with windows, so guess pegs run between transfer and boost ports. No oversizes though......

polaris jet ski piston for a 780cc start at 71.3mm so the third oversize is 72.05mm spot on,, 18mm gudgeon pin but you will need a 116mm conrod,, there is just one oversize left at 72.30,, last one i bought was about 65 quid delivered,, just google the jet ski centre for their phone number and give um a ring.
