I need some help finding out exactly what kinda of harley I have, this is my first bike. I traded a truck for it and know it is a 1977 harley hardtail, but dont know exact model. The guy I got it from claims it is a 1000 sportster but cant find any info on a 1977 sportster 1000? I have a few pics if somebody would take a look at em and maybe give me an idea of what model it may be
