Your local dealer is having you on . The cats on a 2014 roadster are in the pipes , which is why people fit the Tors. If your having problems with the idle and your making smoke , then you need to be looking at a tps , iscv check / reset ! Easily done with tune ecu . If these settings are all to buggery it will explain all problems you are having . If you have run the bike for 20 mins or so there would be nothing left to burn off . Besides , oil burns with blue smoke whereas an over rich mixture which would almost certainly be caused by base settings being awry , burns with black smoke !
