These little gems here are an old tuners trick. You install them on each corner, and it keeps your cylinder exactly pinned where you need it. That way there is no play, and you don't have to guess if you cylinder lines up with all that meticulous port work you did.

This is a universal deal, but you might need to sand them down a touch on some kits.

This is for 6mm studs. Puch for example.
