The real horsepower on old bikes is in the head and ignition. Two stroke engine design has come along way since our old beaters were built so why not do what Deano and Brad have done and modernise the technology without porting the shit out of them.
As soon as I get my act together with the 360 oval pre 65 bike it's head will be on its way.
