I don’t know if you did everything this guy did when he installed 14” bars on his SG, like removing the ignition switch, de-pinning connectors, etc., but it looked like the potential for a lot of things going wrong.
remove the outer fairing and check all connections that you disconnected.
after I confirm I have spark im going to do that. Just weird that it fired before installing the fairing and even now all my controls work. The bike just doesn’t start.
