Johann at Moto Motivo had an aluminum Le Mans tank that was made "by a friend in India" from pictures. Given that I think that tank is the prettiest tank made and I know them "like the back of my hand", I commented that the ridges on the side might be off by 1/4 or 1/2", but it weighed probably less than 5 pounds. I may have to follow up with Johann some more on this. :+=copcar
