According to DC at RacerX:
"Wow, just got an interesting phone call from someone at the annual AMA Congress up in Pickerington, Ohio. It appears that there’s a real chance for a “150cc” rule to be introduced for AMA Sports competition that would allow 125cc two-strokes to legally use overbore kits. Stay tuned—that could have a really interesting effect on the local Lites class."

EDIT:
After reading further, it looks like DC got another call:
"Okay, got another call from the AMA Congress—the new rule will allow for 125cc motorcycles to be overbored to 144cc (for Mod class only). That one barely passed, and another new rule from the AMA Congress will mandate that all 12-to-15-year-old Schoolboy racing be done on 125cc two-stroke motorcycles—just like they do at Loretta Lynn’s. Interesting stuff! Stay tuned for more."
