I say it every time you see my profile on here. You can not kill Godzilla. The 500cc two stroke was designed for Motocross. Now it is time to bring it back. More and more rider's like myself are doing so. You see it everywhere you look someone is doing a conversion of a CR500af or KX500af. They are know putting the 500cc two stroke engines in all makes of bike. KTM500exc is one bike in which I posted a video of. To where the owner immediately tore out the 500 four stroke engine and installed the CR500 in its place. So why does Godzilla always return? Because you can not kill him... I know

But the 500cc two stroke should be allowed back for the outdoor races.
