It is also a great idea to install an hour gaugeon your bike to monitor the intervals. if this part of the skirt is shortened just a little too much, when at tdc, the bottom of the exhaust port will be open and there is a high chance that a reflecting wave of hot gasses can either ignite the fresh charge that was just drawn in by the upstroke, or at the least it could send in already combusted gases which will contaminate the fresh charge, and just as bad, heat it up. Oil control rings are typically made from either a single piece of cast iron, multiple pieces of steel, or steel/iron with a helical spring backing to create the tension required for a close seal.
