'08 Street Glide with 40,000+ miles. The Ambient Air Temperature Gauge is fine at start up, but I start to ride and it goes to full temp at 130. Bounces around for around 5-6 miles and than works fine. The dealer replaced the sensor 3 days ago and everything was fine for the 1st day and now back to screwing up. Maybe the gauge? I know this gauge is not very useful, Just the thought of it not right with the factory warranty being up on April 1. Any thoughts?
