You can pick up a spark plug gapping tool at the auto parts store cheap. Make sure and get the kind with the wire loops since its more accurate. Here's an example:
For a stock or near stock application, I'd gap the TR55's at about .050-.055". Make sure you get the tool that has the correct gap sizes since there are varying ranges.
