I looked closely over the bike as best I could and did not see anything that looked unusual. I didn't see any problems with the frame or engine vin from the photo's. I have asked the seller to provide close up shots of the engine and frame stamps as well as indicate if either has been changed out. As for the rear turn signal lights, they have been modified with a later CB750 light and bar system, but could easily be converted back to original. The recessed ignition is there, exhaust shields, chain guard, double cut fender. I will ask him to clarify the originality of those parts too.
