what Harleys are the parts on this bike from?

Shovelhead motor  (pre- 1987),  stock FLH  frame  from 1996 or later (as disk brakes), and nacelle, Fat Bob wheels..  Short  riser beach bars.  Skinny vestigal seat. Mustang, i think.Good custom paint, from what we can See. K & N pipes ?

I say, motor itself Probably '85 or before as has dogleg..  Slim possibly it is an '87 w/pre '86 gearbox and primary.

Nice Looking scoot but IMHO  I'd like a Full seat. Stock FLH tractor or double for passenger. Paint:"Diablo Azul" on sides of tanks.

Check frame numbers, engine numbers for basics. 30 years old and looks like front end changed? To me that means likely a left turn by car at intersection damaged front, tanks got dented, fenders twist- but engine and frame good. quick back on road using salvage parts, whatever on shelf that would fit, what could be found in friends salvage pile.  I got a BMW R50/2 from Chicago police impound yard after it had been crashed by stolen car.   Next week on road with a R51 front, Harley front fender from K, Harley spot light, mufflers from BSA with VW Beetle glass packs , peanut fuel tank from chopper, small solo seat from a WL chopper that had been replaced with big one for new wife to pack on. Summer season put on couple thousand miles, swap meets got near stock tank and some other bits and pieces. You have cleaned up cruiser, might have been a rat bike for awhile.

shovelhead motor. Looks like a stripped down FLH Electra Glide. Solid wheels from a Fat boy. Drag pipes arent a HD factory part.
