Well got another 100 miles or so on it and another 2 gallons filled up with a second treatment of Lucas..it seemed like it isn't doing it for as long now but it is still sputtering hard when it starts and this morning it did it for about 45 seconds again..not sure whether I should keep putting mileage on it to see if it continues to get better or if I should start looking into other problems.
I have an 07 1200l,it does exactly the same thing,everyone says its just what they do on the early efi harleys,but on another forum somewhere a guy using a dyno jet fuel management product they were able to stop it.Mine dies every now and then.I gotta get it fixed somehow...
