Hi I have and 05 fat boy fuel injected, upgrades are Vance and Hines exhaust, hyper charger, and Vance and Hines fuel pack. I pulled my bike in the garage from a ride and didn't ride it for 4 days and installed some neon engine lights. After installed looked great and I went to ride it the next day and when it starts it is struggling to idle and the check engine light came on. Any ideas? I took the fuel pack off and nothing changed. Disconnected the battery for a bit and nothing changed. Any help would be great. I want to go ride!! Thanks

 

It sounds like it has something to do with the LED install considering that was the last thing you did to the bike. Did you wire them directly off the battery? Did you wire them to a switch? Is the switch in the on off position? Does the bike have gas in it? Is the bike throwing a code? So many questions to ask.
