This is a tool I made a few years ago to remove the cap off of the Trim tubes on pre-2003 (sometimes 2004) Yamaha motors. I am showing it to you here so you can see how I made it. If you need one, I have forms for two more. $30 each. I am in the process of making the hand tool now that is shown as a white paper form. If you want to make your own, email me at chevy_ranger@verizon.net for the particulars on how to make it. You will need a jig holder for your bench drill and a metric step bit to drill out the center.
