AccuReader for the Yamaha YM63 keyway locks with OPPOSING WAFERS currently found on IGNITIONS of FZ-07 models 2015+. It may have spread to more models also in later years. Designed to read actual depths for each space in any of the YM63 locks.

If you run into models that have opposing wafers in the ignition and only have the standard YM63 Accu-Reader, your tool is likely to get trapped in the ignition during use and you may have a difficult time removing the tool. It is recommended that you use the standard YM63 Accu-Reader in the OTHER locks of the bike and not the ignition. Be prepared with this tool to make your life easier.
