In the last 2 days my '06 R6 has been running rough/gurgling for a few seconds on cold starts. Only happens on cold starts. And has only started the past 2 days. Im at work now just wndering what i should be checking when i get home ? Its got a racefit slipon. 11000 KM;s on the clock. Ive only had it since 9000km and since then it has started everytime fine, only the past 2 days its started gurgling likes its about to die for a few seconds then started to idle fine. Anyone have any idea where u should start ?
