i have the bbr 82 kit, ported with hc piston, wondering if 20 carb off my extreme cr107 will pep this up some, I have a 70 carb on it already just expected a little more out of it, btw i think the carb off my extreme is a 20 or maybe a 22? any suggestions?

20mm will be much better than the 17mm 70 carb. You will see an improved response. 22mm too much carb. Bigger is not always better.
