I run a CR250 ignition on my lt500

Red don't you run a full custom set up with a custom hand made triple port cylinder, custom hand coned pipe, and custom porting that you did all YOURSELF? 

I assume because you did all of this yourself that you designed the ports, the pipe to work best with the CR timing curve and that is why you can & are running the CR ignition (CDI & Stator)?

Wouldn't just slapping a CR stator & CDI on a stock zilla make it run like crap because the timing curve does not match the port timing or the pipe design?

I'm still learning and trying to understand this.

Thanks
