I was wondering if anyone has any advice - When i turn my sporty off it starts to die down but then fires right up again and spits and sputters for a second before completely shutting down. When i checked my plugs the front looks slighty Lean and the rear cylander runs a little rich. I asked a buddy at work how to even them out more and he said its fine that most Harleys run lean in the front and rich in the rear. But i fear that the problems i'm having with it is possibly due to the rear cyl. having that little extra gas in it. and that the fact that it does that when i turn it off maybe its just burning that little extra bit. and advice?
