Ah..a typo..yes jemo...I transposed 3875 for 3785..this doesn't mean I am mind boggled by the metric system, just that I can't type...

So jemo, in your expert knowledge and grasp of the subject, what would you say a 550 cc tank holds in ounces (volume) and how much would it weigh, using the rough figure of 6lbs/gallon??

And Hans..sorry, wasn't trying to offend you..I grouped your remarks in with those of jemo. My mistake and I apologize.
