Check 2.A in the Rule Book.

The question was asked in the BMST venue section. The AMA rule book, page 310 for A class (altered frames) states "a. Any combination of motorcycle engines, not to
exceed two is allowed. Combined engine displacement cannot exceed maximum of 3000cc."

Sorry -- I was thinking SCTA.
