bad gas ?

Discussion in 'Motorbike Technical Discussion' started by Larry Blanchard, Sep 26, 2010.

  1. I thought I'd gotten everything working on my SR500 until today. I'd
    drained the tank and had the old flaking liner removed and a new one,
    hopefully impervious to gasohol, put in. That took about two weeks. I
    poured the gas back in and went for a 20 mile ride and everything was
    fine.

    Today I fired it up and got about a block. It missed, sputtered, and
    died. Gas is getting to the carb fine. Compression is fine. There's a
    filter in the tank and an inline filter in the gas line (which I replaced
    just to be safe).

    It'll run anywhere from 5 seconds to a minute or so, but the result is
    still some missing and sputtering, a halfhearted backfire or two, and it
    dies.

    Could the gas have gone bad in two weeks? Come to think of it, that's
    two weeks plus however long it was in the tank before I drained it and my
    aged memory isn't that good. So I guess the question is do the symptoms
    sound like bad gas?

    If so, I'll drain and replace. If not, it's back to tearing down the
    carb again - sigh.

    No. An engine will start and run on really old gas, but it stinks like
    hell.

    You would notice pinging under load if you were riding uphill in too
    high a gear, because the volatile fractions that cool combustion have
    evaporated.
    It's either plugged up jets and passages in the carb or a bad
    electrical conection in the ignition system.

    Well, maybe it's a dead Jamie in the air box?

  5. Oh, how we laughed.

    No, it's just another piece of your laughably errant technical "adice".

    Fuel is FINE. Do a italian tune-up(sea foam) and replace the plug on
    principal then go for a ride...run it dry or close to it and top off
    at a gas station(put in another bottle of sea foam). OH and FFS ignor
    krusty that guy couldn't pour piss out of a boot if the in structions
    were printed on teh bottom.

    Well it would be impossible for ME to get as stupid as a intentionally
    ignorant and stupid inDUHvidual as yourself. I'm just as stupid as the
    average Nobel prize winner.
    guess again...i'm the guy you are so scared of you avoid the state he
    lives in...remember.
    Yep and you are one stupid thing...never changing brake fluid in 20+
    years. Can't get much stupider than that.

    You're terminally stupid and you don't have any retarded friends to
    hang out with.

    Go back to hanging out with the alpacas.

    Or shoot yourself.

    You won't be missed.

    Stop projecting your life issues onto me...
    No, think I'll havng around the house. Work on the fencing, futz with
    some detail work on the project bikes, order parts for one of them.
    Did already shot a whole pot of coffee, had a bit of chocolate
    cheescake for brekkies with the wife.
    Oh I will be...because ain't nobody good enough to hit me with
    anything not even weak ass comments from a closet homosexual who has
    NEVER owned or ridden motorcycles and LIES about owning/riding or
    having any first hand experience with them. Hell you don't even change
    brake fluid you silly silly misanthropic butt sniffer.


    as always your lord and master.

    You're finally learning to prioritize your life to solve your own
    problems.

    That's a beginning, but not the final solution.

    you. Probally all those lazy irish genes.
