Flywheel key

[YamahaUser01234]

So I have been fully rebuilding my 2003 Yamaha’s blaster engine and I got to put the flywheel on and noticed I didn’t have the little rectangular cube for it does anyone know where I can get it the hole is where the key goes is on the top left side of the flywheel if your not sure what I’m talking about.

It's actually a half moon key, available at any Yamaha parts supply.
It's metric, hardware store won't work.
Modify your stator plate so you can advance it about 4* , well worth it. Nice increase in low and mid RPMs
