BAH! Witch hunters... all of you! I'm planning on upgrading to 720cc's soon. Yeah, I might go with the other guys. My Venoms served me well for years as a daily driver, and many passes down the dragstrip. I didn't have a problem with mine. I even took mine to get checked before I reinstalled them, and they were fine. But my plans for my engine combo is going to need more fuel. It just seems like I hear alot of bad stories about Venoms, but hardly anybody has any real proof. So my experience with them were good. I can't speak for everybody though.
