GAS PROBLEM?

[BARNES]

I HOPE THIS IS THE CORRECT SPOT FOR THIS QUESTION. I HAD WRITTEN BEFORE CLOSE TO THIS SUBJECT ON JULY 7 OF THIS YEAR BUT IT WAS UNDER BATTERY. MY QUESTION WAS #1539. I HAD SINCE FOLLOWED THE ADVISE OF REPLACING THE "BAD GAS" WITH NEW GAS BUT PLEASE NOTE THERE IS A LITTLE OF THE OLD STUF STILL IN THERE. I HAD ALSO ADDED AN ADITIVE. WHEN I START TO ACCELERATE, IT IN A DESCRIPTIVE WORD "PUT, PUTS" TILL IT GETS GOING. BEFORE I REPLACED THE GAS IT WOULD STALL ON ME. NOW IT GOES BUT IT STILL DOES NOT SOUND HEALTHEY TO ME. THE BIKE HAS ONLY 470 MILES ON IT. IT IS A 2005 SPORTSER 883XL. WHAT ELSE CAN I DO TO MAKE IT RUN RIGHT. SHOULD I JUST GIVE IT TIME AND KEEP RIDING IT. I HAVE A FEAR THAT IT WOULD STALL ON ME AGAIN ESPECIALY STARTING ON AN INCLINE. MANY RIDERS I HAVE SPOKEN WITH SAYS THEY HAVE NEVER RUN INTO THIS PROBLEM WITH THERE HARLEYS. ALSO WHEN I TOLD THEM THAT I HAD CHANGED THE OIL AT THIS AMOUNT OF MILES AND IT WAS BLACK. IT WAS LIKE IT HAD NOT BEEN CHANGED WAY OVER THE APPROPRIATE MILAGE. PLEASE ADVISE ON HOW TO GET MY BIKE ON TRACK AND THANKS FOR THE ASSISTANCE.

First the oil, it will always be dark because one of it's jobs is to remove contaminants. Of course without seeing the drained oil it is not possible to judge if it was in fact burned or contaminated with fuel. You may have an ignition module problem and could be checked by replacing with a known good unit (password learn required so it's a dealer thing). Typ. I would guess a restricted air cleaner, your milage does not suggest this but still worth looking into. Another pos. cause could be an idle setting that is too low. Easy to try (even if it feels like it is idling too high for a while). The accelerator pump may also be sluggish or not working properly. It is not unusual to simply have a "bad" carburetor requiring replacement (warranty?). Sounds like a trip to a tech may be required.
Thanks, Mike
