Has anyone out there got both a new M20 piston, and also a set of Gram scales?
I need the weight of a piston, gudgeon pin, and rings, for a project.
Many thanks.
I see from Henks figures that the Heplex I weighed is heavier than the BSA pistons he weighed...
So Henks figures for original pistons would be the ones to use in any calculation...
Italian and other pistons are also heavier than originals....
It seems in each case a decision has to be made about adherence to the original balance factor and whether rebalancing is desirable/necessary...Ian
