206 Rulebook for 2023

So I was cruising both the Briggs 206 rulebook and the CKNA Rulebook and I’m no longer seeing weight requirements for cadets, sportsmen, and other juvenile classes. Are I missing something?

I have a 9 year old racing this year, and I thought kid+kart needed to weight 265 lbs. But I can’t find it listed like I could in last years rulebook . . .

Any insight is appreciated. Just trying to make sure the kids are legal and they make that transition from local racing to CKNA.
