Looks to me they knew exactly what they wanted and exactly how to remove them fast and had the right tools handy. You were cased and hit by pros. Just the way they left the speedo makes me think experience. Were the fasteners left behind ?
Your local cops might have some ideas and possibly a nearby bike shop might know someone who was pricing out those same parts , seat and tank. Notice they didn't take speedo or side panels , battery etc.
They needed replace old ripped sear and damaged tank. Maybe they were bringing bobber back to stock .
Bags and windshield too easy to identify.
Keep it kinda quiet and Set up decoy with what is left. Maybe use trail/hunting camera. They might find they need more stuff and thieves aren't usually very smart. Pigs come back to the known trough. Look around at folks who work there or near by. A little thought and logic cane sometimes go a long ways .
Now here is one thing
and I see differently.......course I don't know the concealed carry rules where he or you are. Where I am it is pretty strict but I'm a second amendment guy ready to go to federal court any time. I don't think the State want my kinda case cuz if they lose , there go their illegal rules. Already got one case dropped pretty sure because they didn't want to take that chance. Gave me my weapon back and all. Now don't get me wrong , I wouldn't shoot them over a bike.............I don't think. But a wet spot would give me a good laugh.
I'm an old fud , but some things really p*z* me off and messing with a perfectly good bike that isn't theirs is one of them.
