After removing the complete Cat my bike did start very bad , rode to dealer and told him then the technical master did set the "ignition-modul" ( i don`t know exactly how he named it ) back to 100 ( to let it learn again from beginning , he said ) ,Does anyone know the name of this module ?
Now i am back from a 1k miles trip from paris through the champagne and elsaß and Pfalz and normandie and and and night-paris-tour through the mad traffic of this huge town and all i can say : WOW !, the bike runs like a speedy goncalez , like a horny rabbit , great improvement in torque ( so it seems to me , no dyno-test yet in this configuration ) and it feels like the bike is a free willy now or a wild horse , REEESPECT to my technician who did this .
Now i am serious thinking about not to take the supertuner , i guess i will leave it as it is when there will be no change into a bad performance . ( No other mods , still stock mufflers ) .
