    E10 or E5 Fuel?

    From the Gov.UK website:

    "Kawasaki
    The below Kawasaki motorcycle models are compatible with E10 petrol from the year of manufacture stated. If your model is not listed, or it was manufactured before the stated year you should continue to use E5 petrol:

    KLX125 - 2010
    D-Tracker 125 - 2010
    KLX250 - 2008
    Ninja 250R - 2008
    Ninja ZX-6R - 2007
    ER-6n - 2006
    ER-6f - 2006
    Versys - 2007
    Z750 - 2007
    W800 - 2011
    VN900 - 2006
    Z1000 - 2009
    Z1000SX - 2011
    Ninja ZX-10R - 2006
    ZZR1400 - 2006
    1400GTR - 2008
    VN1700 - 2009
    VN2000 2008"


    In other words, your ZRX needs to be running Super Unleaded as that's still E5.

    That seems a very odd list of models there, find it hard to believe its exhaustive. Looks like they just cobbled a few models together where they felt sure things would be ok rather than look further at it. Yamaha on the other hand say all their bikes since 1990 are fine! What are the differences with what Yamaha have done with the carbs they used etc that makes Kawasaki models incompatible with E10? I've been using E10 in my Diversion and notice no differences really if anything its smoother at certain rpm, I suppose only time will tell as to what affect it has on carb seals and stuff. I've used super unleaded in the ZRX since I put JE pistons in though as it seems to prefer that with the added compression. I suppose if things go it will just mean replacing parts with more ethanol resistant seals and stuf but as I understand it its long term degradation that happens not something overnight.

    A trusted motor cycle engineer I have known for years showed me an industry article breaking down the wisdom of bio ethanol in fuel i.e. going from E5 or 5% to E10 or 10% in your fuel. In short It's down to eco and cost reasons, not better engineering reasons.
    This article highlights that this fuel is hygroscopic and will absorb condensation in your tank, which will pool at the bottom and rot it through.
    We all know that water in our carburettors, if left in place causes all kinds of issues, E10 is just doubling this. Lastly it states that after six to eight weeks fuel should be classed as old and will be breaking down and absorbing water. So we need to be draining tanks and carbs each Winter. Leaving E10 shit in your bike will fuck it up.
