I went to this site but couldn´t find a G-1. But I had one of the first 900´s featured this month. My serial # was around 3000 on that one. Where did you find the Classis info? The one on this forum isn´t original it must have been converted to Carbs, the covers aren´t original. Like I said email me direct at frankbon@epix.net if have any more questions.
