I just put on a powerbomb header with exhaust. Of course it was night when I noticed it was glowing red. I haven't had a chance to make the efi changes, but I plan to. I'm sure it might be running a little lean. Is there any danger with the glow? I've read it's common for it to glow especially at night. Like I said, I'm hoping when I make the powercommander changes that it reduces it a little.

You need to install the powercommander and load the correct fuel map. Running the bike too lean can cause problems and shorten the life of your engine.
