Multi-classes for AMA

[NXmarty]

Hello ou there,
                    Can someone tell me if a person can run two completely separate engine classes, but use their same bike? What I am trying to say is, I want to put two different motors in the same chassis and run.
Is that a legal thing to do at BUB. The classes would be identical except the cc's.For example 250cc A-AF/ and 1000 A-AF.what do you think?

Certainly legal. Would have to be re-inspected. Don't get too ambitious, better to keep tuning in one class. Since you are running NO2 maybe the class change would not be by choice.
