Hey all... Recently purchased an 04 Electra Glide Classic. 33k miles. Stage 2, Ultima six speed transmission. Just had the 30k mile maintenance done. Every once in a while I'll get the 6 fast blinks from the indicators. Just filled it up, when I fired the engine, it backfired then started fine. Bike doesn't show any other symptoms of poor performance. What should I do? Should I be concerned? I thank you in advance.
