I am the second owner of an '07 883L & am not sure how to tell if the motor is powder coated or painted with high temp paint ? It has a Nightster look , flat black heads & jugs & gray side covers. I would like to file / sand / or grind the fin edges I can get to , to create the same effect i've seen on other Harleys ? Not sure this would cause other problems like paint peeling / separation on the fins ? Two of the attached pics are from a cellphone , not so good of an image . The bike looks a lot nicer in person. thanks for any info.
