I just bought a 2002 Fatboy & the guy I bought it off of had taken the baffles out of the stock pipes & put a screamin eagle air breather on it & that was it. I have noticed that the pipes are blueing beyond the heat covers, is there any connection & should I be concerned or is it ok?

Your engine is running lean on the fuel/air ratio. The pipes are blueing from the excessive heat. Think of what the heads / valves, etc., are experiencing.

Richen up your fuel mix with rejetting or a remap.

Do you have a carb or FI?
