Dropped my 08 sportster 1200(fuel injected). On the initial attempt to start the bike, it starts up fine. Once it warms up a bit it tries to die at slow speeds or stopping but can be counteracted when given a lot of throttle. When I turn it off, it won't start again unless I give it full throttle while trying to start it and this takes a good second before it will finally start but still tries to die unless given constant throttle. I'm new to riding and want to see if this is an issue I can learn about and fix myself. Thoughts??
