There is a plan hatching to life during all of this. Everything below the head gasket is built as strong as I can make it using parts Triumph Performance developed for their turbo bike. It can handle fuel, nitrous, a blower, etc. The cylinder heads contain all of the goodies on these overhead double knocker motors. It is easy to swap heads and it can be done with the engine in the frame.
The head I am working on now is a mild NA setup with 11.5 to 1 compression, a port job, 2mm larger intake valves, and the 813 cams. It is what l will run in AUS. Next year I will buy a used cyl head in good shape and enlarge the combustion chamber so the compression ratio is 9:1, and it will have standard valves, a Triumph 865cc intake cam, and a Triumph 790cc exhaust cam. The low compression head will be what I use on the street and with spray for racing.
The big plan is to run fuel or gas, whichever I want.
