So, I'm thinking about going this route as well. I already have my recovery bottle re-located in the old airbox under the seat, but want to free up that space. My only problem now is do I want to use a 3"x10" bottle like the one used by the OP and in his pics or go with a smaller bottle like a 2"x10". I did a little measuring and the stock bottle filled to the MAX line held @ 11 oz. The entire stock bottle filled all the way up to the cap was @ 22oz. Now, it doesn't hurt to have a larger tank, but is it really needed? The 2"x 10" bottle is supposed to hold 14 oz. and the 3"x10" bottle says it holds 32oz. Either will work, so looks like it's up to personal preference. Everything on the bike is BIG, so the big bottle would definitely fit in w/ the overall look of the bike, but I'm thinking the skinnier bottle will blend in just as well and may help with those needing the extra space...
