Page 14 - 2004 rule book - Engine Class Break chart. Ok, we are considering running in the J class and using a 750cc motorcycle engine. The chart says 31 to 45 cubic inches and it says "Approx. Liter Equiv." "0.51L to .75L". I did the math. 45 cubic inches is equal to 737.42cc. and I determined that 750cc is equal to 45.76 cubic inches. So my question is if I show up with a 750cc engine (45.76 CI) is it legal for the J class? Thanks Art
