piston rings for Fazer 600

[unfazed]

easiest way  is to place the ring in the barrel and measure the gap you do this in two places one about a inch down from the top of the bore and second about an inch up from the bottom that way you can tell ring wear and bore wear

Repeat the above process with new rings to determine if the bore requires replating as they are nikasil plated bores, don't forget to check the ring side clearance, with the old and new rings.
