@irongamer727 Not to my knowledge, the little box on the side of the air box can also be found on the competition bike WR200, they wouldn't restrict a competition bike. At least that's what @AndyYam told me. And he has a lot of experience with all of that.
Secondly, the PowerJet, to my knowledge (Happy to be corrected) is a clever mechanism to lean the fuel off at wide open throttle, when actually you don't need as much fuel.
The logic is that at WOT, you should be easing off the load of the engine and now it's all about refining that combustible mix. The leaner you can run that engine, the better the burn of combustible mix can be.
The trick is to lean it off as much as possible, without causing detonation.
