Hawk wrist pin diameter

[Robinhawk]

Hello everyone, got my hawk in march and have been modding it a little at a time. I see that ebay has cylinder kits for $76.95 and I thought for that price I'd put one away just in case. Messaged the seller and they said the wrist pin diameter was 16mm. Is this the same as the hawk engine? Anyone bought one of these kits? And thanks everybody for all the great info!
