This lets you connect a timing light to the Yamaha blaster and check the ignition timing.

The bolt holes on the timing mark are snug and designed to have the bolts threaded through them and then into the case.
The arbor lines up to the keyway on the flywheel. you can lightly tap it in to seat it.
The Flywheel marker has a lip recessed 0.5mm. This is to helps you get the marker or which ever tool you use to mark the flywheel to be a little more accurate.

This is useful when changing the stator timing or setting timing with the Nasty Fast Adjustable CDI. https://www.ebay.com/usr/nastyfastparts I have the newer 03-06 CDI avaliable too, shoot me ma message if you have questions.
