Anyone put the sparks full system with big core on their YFZ's. What kind of results did you see? I am just curious if I should get the big core or the standard core and does anyone know the true difference in performance?

From what I've been reading, unless you have motorwork you're wasting your time getting the bigcore. It's not for stock motors.

Is yours the big core version, or the standard core?

I know my big core was ear splitting loud. It was the best top end pipe I've had. Lacked on the bottom with my motor being stock.

The way I understand is exactly what it says. The "big core" has a bigger core, therefore your going to have more on top end. Which would be better for sand dunes, drag racing, or flattrack. The standard core is a smaller core so you would get more bottom to mid range power. That is the way I believe it is.
