My bike has been running really rich I talked to some one who told the 02 sensor was probely bad, well I replace it and that was not the problem. so I was running the bike and the second cyclinder was not getting hot like the rest of them ,so I pulled the spark plug and the plug it was soaked I am getting spark. So can the injector be stuck open? or is the computer telling it to stay open. Just installed a new battery and did the throttle two times to reset it.
