    It would not be the first time BMW has failed to disclose all.
    Remember that Brazil and other ethanol using countries put additives in that prevent the acidity and tendency to attract water.
    I spend $150 a year on engine treatment fuel additive and ride around 20,000 miles between all of my bikes.
    All my bikes get the same fuel treatment at $0.38 per gallon cost. Even my 2 carbed bikes like the cleaning treatment.
    It just seems crazy to not spend a little preventative money if you live in an ethanol crazy state.

    For the record, I use the Techron fuel system cleaner regularly, and a splash of red-bottle HEET also.
    I have 30K miles on my bike after 40 years, and have had only a handful of stalls and no other fuel system issues.
    My bike never sits still for more than a couple days, so I'm sure that helps.....

    I'd not heard about the nitride coating .... sure would like a pair of injectors and a fuel pump with that stuff!

    Are you aware of the mechanism by which techron keeps aluminum oxide from building up the injectors?
    As "inert" as aluminum oxide is, this would seem a challenge?

    I think it lubricates the aluminum oxide particles so they don't bridge and wedge in our injectors.
    They are small enough to flow thru the injectors except when they log jam in and wedge.
    That is why if you fill up the bike and it is at empty the concentration of aluminum oxide seems to be the greatest in the fuel line and tapping the injectors with a wrench will sometimes get the bike to start. This has happened to me many times in the first thousand miles since I go the bike new in November and rode it very little while I was modding it out. Since using the treatment I have had flawless quick starts these last 3 years and 40,000 miles.

    That could well be it...........
    If so, I wonder if we could just add a bit of 2-cycle oil to every tank full? :evil
    It would save us considerable money.

    Do we have any dedicated users of SeaFoam on the thread?
    It is a mixture of some sort of light oil, naphtha, and isopropyl alcohol....
    But still demands a good price given it's relative formulation simplicity compared to Techron.....

    Yeah I have been happy using Seafoam these last 3 years.
    Even cleans up gummed up carbs.
    I buy 24 can case of 16 oz cans for $6.11 per can online delivered.
    That works out to $0.382 per ounce or per gallon of gas used.
    24 cans usually last me a season or 20,000 miles of riding for me.
    At these prices you wont find 2 stroke oil any cheaper.
    But I suspect you are right and it may do as great a job protecting the pump and lubricating and cleaning the injectors.
    The isopropanol in Seafoam also ties up the water from forming an acid with ethanol.

    I just got a case from this website last week:

    http://www.shopthedude.com/searchPr...TdHJpbmcga2luZGV4LnNodG1sAMEApAhHiHzgxAgSRAAA

    I shopped around and end up buying the case from several websites these last 3 years.
    I refuse to pay $10 plus per can retail at stores in town.

    I would never even consider purchasing a supposed "Adventure" motorcycle that would require me to carry a bottle of fuel additive with me every time I go on an "adventure" ride, or else likely end up stranded; that's just freaking ridiculous!

    If all the other bike manufactures can build a proper Adventure bike in this class, why can't BMW?

    I agree, I love the bike otherwise, but why not just positively address and remedy this issue? :huh

    Stainless steel fuel pump would really help.
    Removable fuel filter would also be nice.

    2009 f650gs twin...2x such failures luckily within 10 miles of dealership...still required "towing". Unbelievable for a supposed any 2009 bike, much less one badged as a GS.

    Out here in my little town there is a gas station that sells Premium w/o ethanol.
    I gotta say when I rolled out of the dealership more than one of the mechanics told me to use only premium gas and add the BMW fuel additive. After reading this string I see why they went on and on. Gotta say it all makes since. ADM messing with fuel, engineers adapting to new fuel and riders doing their PM's.

    I for one just came inside from adding more fuel additive to my tank - :evil
