the stator has metal on the ends of the coils and the flywheel is lined with magnets so after the gasket pops loose it'll be the strong magnets folding it. just get hold of it tight and pull hard.
yall wanna know a cool thing??? my DR650 has the same exact stator, source coil, and pickup coil as warriors i had a extra warrior stator laying around and it tests the same as the suzuki in everyway and bolts into the cover.
