RE: New Saito 4 Cycle Gas Engine, 3 Cyl FG-84
Hmm interesting concepts. For sure if you can get a LOT more HP from the engine it should be worth it. You would be saving fuel and gaining HP. The only questional part would be the journal on the crank and the Crod duralability. Meaning if they could with stand the additional power. I suspect they could, just musing here. The other issue could be the cam and the duration and size of the valves.
Just some thoughts here.
