Here is the problem....
On decel when coming up to a stop light ect or a few second after I start it up my bike will stop running on 4 cyls and start to sound almost like a twin. It will idle like that. When I take off from a light, or rev it a bit, its like it clears out and then runs fine. It doesnt do this much, I rode around for a few hours last night and it did it maybe twice or three times, lasting a very short time. It did it to me last year as well with a different exhaust on it and a custom tune. This year it has a brocks pipe and a map from brocks and its still doing it about the same amount. Sometimes when I ride it doesnt do it at all. Last year when it was doing it I swapped the plugs and it still did it occasionally. Any help would be appreciated.
