To me the only diff between this year and RC in years past is consistancy. He has always been a rocket ship. The trick though, as it seems he has figured out in SX this year, is to go fast consistantly.
First of all the AMA does do teardowns. Maybe not in SX but I know for a fact they do in RoadRacing. Remember the Pridmore issue a few years ago. They gave him and his team crap for using a special winscreen and front fairing. I dont' know if it was more aerodynamic or if it gave him better wind protection. Point is the AMA was on his ass and he was winning and dominating most everything in sight in the 750 supersport class at the time. WERA also does dyno tests to avoid the time consuming process of a tear down. If you exceed the HP limit for the class you are out. The AMA can do the same damn thing.
Even if the AMA isn't doing teardowns after every race you can bet your ass that if another rider had protested and shared the same opinion as you they would indeed pop off the head and cylinder of the Kawai and inspect that engine.
Why don't you give the kid the benefit of the doubt until he proves otherwise. Let's not forget that the kid has always been one of the fastest guys out there. He has won from the front with a holeshot. He has come from mid pack to catch everyone including the king and win. He has also gone bar to bar with the king.
He has always been fast it was just a matter of time before he found the consistancy necessary to be successful. You should be happy for him.
