Have been looking for an older (49-65 ish) K-750 and see bikes which seem to have parts from late 70's -90's bikes? Any advice on what to look for or how to tell if the bike I choose is period correct. I am looking at a couple locally and both are in the $7000 range which I thought was steep for a non-restored bike which cannot be verified. I am looking to restore and enjoy the bike, not make any money and do not need a "numbers matching" but it would be nice to have a correct complete bike.
