Swapped to 18lb valve springs for some extra rpm and speed

[IfYoureNotFirstYoureLast]

I wanted to get a little more speed out of my yard kart so I swapped to 18lb valve springs to pick up some extra rpm before valve float. I was pretty pleased with the results just from swapping the springs. Here's a video link showing the difference between the factory predator springs and the 18lb springs.

I REALLY hope it's got a billet rod and 'wheel, AND the governor completely removed.
