I don't post Dyno pics often, but this one seemed worthy. The engine is a BundyBuilt 509 Yamaha YZF for an outlaw kart. I post this because it not only shows our product development, but also how good the engine is. The red is our standard stack and the blue is the second injector stack we are working on. We do expect more gains as this was the first run on the system. It will be available on every BundyBuilt Yamaha 509 outlaw kart engine. Contact Bundy Built for all our products. 704-662-3333
