Welcome. I see a few problems. First, I wouldn't last 10 minutes on that seat. Second, you definitely need some mufflers. And I'm not talking about the loud pipes thing here. With open headers, your engine does not have enough back pressure to run right. I don't know what kind of air filter that is, but if it flows more air than the stock filter in the stock airbox, it will make things even worse. It may run, but it may not run for very long. The A/F mixture will be way off no matter how it is jetted, and the open pipes will burn the exhaust valves.
