Im not saying that at all, your getting my words mixed up. I personally dont mind the large oversized tank but like I said I wouldn't cut up my fullbores just to fit one. I said "MOST GUYS" wouldn't run one because they care about looks, and probably spent a pretty penny on aftermarket/custom painted plastic. I do like some bikes that run the tank, it's not as bad as most people think. But then again everyone has their own opinion, and obviously if people were concerned about their gas mileage, wouldn't we all be running an oversized tank? But that's not the case is it?
P.s. - Nice Wheels!
Sure I can come up with a drawing, but I probably wouldn't go with the injection mold. Like you said it is very expensive, I think a custom aluminum tank would be more affordable in this case. I honestly think it's worth the extra gallon, but who know's how much it will hold at this point. I mean look at IMS and their 4 gallon tank, it's a lot smaller than the huge 5 gallon, costs the same price and only holds .8 gallons over stock.
