    hi everyone.. I dont know but for some reason, when i turn on my bike, black oil (i guess un burnt fuel ) is sputtering out the exhuast. Not near the manifold, but near the muffler tip, and the bolt ....
    the bolt it tight on there and snug. Also i have a new sparkplug in, and had the needle clip at the stock position, and the plug was a light grey, so i lower the clip to allow more fuel.. its on the 3rd position from the top.
    I dont know why its doing that.

    the recent modification i have done is get a better inline fuel filter from O'reilys auto parts. and it put it on where the arrow points at the carb, but it would cutoff like gas wasnt getting through ( but i could see gas fill up in the line) then i made the arrow point upwards, and everything was good.
    also i used i think 6 or 7 oz , i dont remember of oil to 1 gallon of gas.

    idk, but its a problem i got to fix.
    please help

    We sure do want -- to be exact with gas oil mixture ratio -- a little rich, not much damage --- but - too lean and possible major problems.. Happy Riding from - Mountainman

    Anytime we see big differences in color of exhaust -- SOMETHING IS GOING ON -- we need to check it out ASAP.. I wonder if your engine is now - due to oil mixture or other problem - shot out ?? Please let us know - what you find.. Happy Riding from - Mountainman
  5. Please realize you have a 2 stroke Motor NOT a four stroke.
    If a four stroke shows Smoke you may have a problem as the motor is design to be lubricated with a independent oiling system.
    On your 2 stroke the Lubrication system is dependent on your Oil to Gas ratio.
    Seeing smoke is usually a sign of a rich Mixture.( oil mixture to gas is being favored by oil).
    Not a bad thing but the engines performance may be cut back Or a spark plug may foul or you may see some smoke coming from the exhaust with a possibility of A bit oily By product dripping as well.
    You may wish to check to see if ALL your Gaskets are all good and Properly Tightened Including the head Gasket.
    Next time you Mix your gas keep all this in mind as your pouring in the oil.

    thats what it probably is. I think my mixture contains a little to much oil.

    once i run out of gas, i will take that into consideration.
    or should i change gas/oil now.

  7. If you asking for my personal opinion.
    If the bike is running and keeping a good idol.
    Knowing in the back of my mind the Mixture may be a tad too rich I would operate with caution and run the bike until all Fuel is Gone.
    Then Remix And try again.
    The decision is totally up to you.


    And good luck
