Returning to the topic at hand, when you win you're subject to scrutiny. It's the rules of the game. As for any extra curricular scrutiny, not likely. In 25-30 years, the closest I can remember George to cheating was figuring out there were advantages to having a lite rider and putting Angelle on the bike. The result of which allowed him to run an extra vacuum pump on the motor. The heaviest bike in the class still made weight and was dominant.
You can bet they were running it on kill, that's why internal parts made contact with the pavement (a first for a Bryce bike that I can remember).
Chip has been running dominant numbers for a few races. The weather just allowed a pass this quick.
