cunka72 Posted November 30, 2013 Share Posted November 30, 2013 Has anyone seen a piston like this, i recently take out a piston for changing piston rings and i saw this hole one the side to exhaust.Should i purchase new piston or just new piston rings?WHere do i measure piston or cylinder bore to find out what is my piston size?Should i bore cylinder for bigger piston?Thank you very muchGreeting from Croatia http://imageshack.com/i/m914b9j http://imageshack.com/i/2hejzkj http://imageshack.com/i/ngk2j1j Link to comment Share on other sites More sharing options...
