    Great idea even if it only allows greater protection from dirt and water in fuel.

    The basic theory is similar to changing the diameter of emulsion tubes in weber carbs to provide greater fuel reserve so the level around the mains remains constant.

    I would not expect huge gains as mentioned by the crf250 owner on the link but it has the potential to make it smoother. I would expect gains on larger engines as they require more fuel.

    Least it comes in red, the thought of anything blue........well it is enough to make one sick.

    Seems a little pricey though.
