2007 dyna low rider FI does not start first time every time. Notice this most after fill up's but other times too. Runs good after it starts and idols fine.
A common issue on FI bikes is the rider trying to start the bike before the injectors are done priming. When you click the run button and the injectors start to prime....wait until you don't hear the noise anymore before hitting the start button and see if that helps.
