Just joined the site, so I'm posting what issue brought me here. I changed my oil and filter right little before sundown. Had to take a phone call, and by the time I got back to finishing it was already dark. Sun sets fast here in west. Anyhow... I started up the bike and let it idle to warm up the engine for a final oil level check. While idling, I listened for engine sounds. I been thinking that maybe I been hearing an exhaust leak for a while now, but still not sure. So after about 5 minutes of listening to the motor, I noticed the pipes (underneath the heat shields) up by the engine head were glowing orange. It wasn't bright orange like cutting metal with an acetylene torch. Was kind of faint orange. Took my jacket, threw it over my head and the fuel tank to block out the street light, and sure enough, it was glowing. It's my first Harley, so of course I'm thinking something maybe wrong. But I do a Google search, and find a thread on this website that told me this is to be expected if you're gonna run at an idle for very long, and I should just go ahead and ride it to warm it up. I measured the 3 quarts of oil, so shouldn't be off by much, if any at all (HD manual says 3 qts for oil and filter change). So I'm feeling a little stupid, but I guess this is how you learn. I would thank the veterans in the thread, but its from 2010, so will just say thanks here.
