Itsa bitsa. New London is part of my AO. Never seen that one, not even back in the day. The pic of the engine is from a TR5, not the bike in the rest of the photos. That guy's dreaming if he thinks it's worth that much. A 750 big-bore kit without a crank balance job is going to be a real shaker. Parts bike... I ran a set of those scrambler pipes on a '69 Bonneville with a 750 kit, cams, and some head work. Can you say LOUD?
