I've got a 2002 cr250 and would like to carry more fuel, a lot more. I'm aware of the 3.1 gallon IMS tank and the 3.2 gallon Clarke tank, but are there any other players in the game? As far as I've found, Acerbis and Safari/Aqualine don't offer anything. I'd like 5 gallons if at all possible but so far it looks like my best bet is the clarke with an Acerbis .8gallon number plate tank (the 1.3G is way too bulky.) I'm not interested in carrying anything in my backpack or fender bag and am looking for something that will mount to the bike. Does anyone know of a side panel tank (similar to this: http://www.justgastanks.com/store/index.php?main_page=popup_image&pID=574 ) that fits, or any other options that won't get in the way of riding?
