well to make a long story short.... I picked up a matching numbers 1972 Bonnie cheap and was told the engine had been rebuilt, from what I can see it has been, rebuilt the carbs put on smoe stock things to relieve it of bad 1970's add-ons and she is alive and well with not a puff of ol' blue.... I'm so proud of her!! OK it's been two years since I have had a bike on the road.... worked on lots and road lots but not one of mine!!!
