RING SETS  
NOTE: It is common for the tapered lip that came in the bottom of your cylinders from the factory to be removed when installing larger bore piston kits. If the machine shop doing your boring does not taper the bottom of the sleeves after they are bored there will be a sharp edge at the bottom in place of the factory taper. It will need to be removed to make ring installation easier. You can taper the sleeves by hand with a Dremel tool or porting tool using a small 400 grit or less sanding drum. It is also very important to wash the bores with hot soapy water to remove any sanding residue and oil them lightly when the tapering job is complete. We recommend lightweight machine oil or engine oil.

Following this procedure will greatly reduced the risk of broken rings during installation!
