this is a great thread --- and no im not taking it to personal----i will try to explain something to everyone ---the motorcycle classes have 3 sections--the frame classes - P,M,A,MPS,APS,SC,SCS and S.The engine classes there are BF, BG,F,G,P,PB,PB,PBG,PF,PG,PP,PV,UF,UG,VBF,VBG,VF,VG, and omega. Then we have engine displacement classes. Shown in Cu. Centimeters 50,100,125,175,250,350,500,650,750,1000,1350,1650,2000,3000 and 3001 and above. In P and M and MPS you can only run one engine. In A,APS,S,SC and SCS you can run two engines. Now here is the tricky part... Even though in the rulebook it lists any record over 3001cc is listed as unlimited, thats a mistake. It should be listed as 3001cc and above, and not unlimited. The unlimited class is an engine class and there are two classes, UG and UF, Unlimited gas and unlimited fuel. In Unlimited gas and unlimited fuel there are no engine size classes. You can run any reciprocating engine that uses the otto cycle, In streamliner class only. Super charged engines do not advance class. So yes, in unlimited gas and unlimited fuel you can run two big block chevys, with or without a blower in the streamliner class or two allison aircraft engines. That's 7.J.12 in the rulebook. Also in 7.D.4. It says you can run unlimited fuel and gas in the streamliner class, the sidecar class and the sidecar streamline class-----.george calloway
