What my engine type?

Whizzer Panther, 2003, I think. Looks like the stock engine.
My son in law bought it and came with a engine head and piston.

What is the engine type: WC1 ,NE5 ?

thanks

2003 is a WC-1 engine. a cylinder upgrade is needed for making it reliable. Quenton is the man to talk to about this fix. I modified my 2000 WC-1 to an NE5 with parts and info from him and I'm very glad I did. It runs very well.
