50cc head on 100cc big bore kit? 100cc cylinder displacement compressed into around 6cc stock head combustion chamber = around 16.6:1 compression ratio! For comparison . . Sym Mio 50 is around 12.6:1. Then factor in running high-octane gas which RETARDS combustion closer to piston top-dead-center . . then installing a "performance" CDI which ADVANCES ignition timing . . and the result is yet another FUBAR BBK conversion!
