Am I the only one who reckons that this will not make a difference? To explain my thought pattern as to why not: Lets say you take a bucket and mount a funnel on top with a piece of pipe connected to it, the pipe goes halfway down the bucket, you now start filling this bucket via the funnel. Does this now mean that the bucket will only fill half way? I think not. I might be mistaken but fluid dynamics dictates that one doesn't need to disassemble one's brand new bike in order to get more fuel in.
I might be completely wrong or missing something, but that's just my logic.
