I've posted this question somewhere else. Does anyone know for sure what cc is the Screamin' Eagle 131 piston dish? Must be fairly big to only yield 10.7cr with, I'm assuming, 95cc head chambers. - Rob
The lowest compression 131 pistons (https://suburbanharley.com/Parts-Catalog-M8-Pistons) I found, were from Suburban Speed, -12cc.
Thanks, I know of the Suburban piston's which could be an option, but I would like to know what the cc dish is for the Screamin' Eagle pistons as they are cheaper to purchace here in New Zealand. - Rob.
