[QUOTE="whenfoxforks-ruled, post: 1225414, member: 73147"] Going to long on rebuilds,I believe is the prime source for distorting cylinders. They come that way occasionally,different plating does different things and the aluminum behind the plating moves. Us chrome has the thickest plating and very good at fixing bores. Checking and staying on the bridge clearance is important,but when a piston,ring wears it lays into the bridge and looks like a bridge seizure Whatever your bore clearance is the bridge relief should be double that! And the bridge is the best spot for flashing to build up. [/QUOTE]
