You could have an exhaust leak at the pipe to head union. What does a new spark plug look like after running for a few minutes? If it is bone white, your engine is running very lean.
It could also be a timing problem, especially if it is popping back through the airbox. With this situation, I would not run it hard because you are probably close to seizing a piston.
