Today was my 3rd ride on the new S4RS; I have had some idle/ flame out issues. That is, the bike dies suddenly then has trouble idling upon restart. Usually in stop/ start/ stop traffic. The bike seems to be running strong & pulls hard. Until it happens; but even once it refires, a couple of healthy blips clears it up. The bike has a K&N type filter (branded as Ducati Performance), a QD exhaust, & TPO airbox veolcity stacks. I have no clue if the previous owner reflashed the ECU. The air cleaner is not fillthy; just used. I have yet to check spark plugs. Any old gas the bike had in it is long gone. Do these bikes have fuel filters? And, has anyone else had similar issues? Thanks in advance.
