    Smelly Vision

    Post  VFan on Thu Jun 25, 2009 4:25 pm

    My '82 XZ smells of gasoline to a point that I'm not able to store it in the garage but instead keep it outside. My initial assumption was that the petcock was leaking through the primer opening and draining into the engine but when I set the petcock to "on" is seals tight and there is no leaking at all through the prime gas line. There are no signs of gasoline anywhere that I can see, on the engine, frame, or the cement underneath it. Any carburetor openings that I should be looking at or any other suggestions?

    Any ideas appreciated

    Could be your tank cap sealing badly.

    You could also be weeping from the carb drains to the middle of the V. I've had this happen for no good reason a few times.. stinks up the garage like mad.

    Cool If you don't have a visible gas leak puddle/stain on your garage floor, remove the gas tank and look, on the top left side of the carbs, you should have two clear plastic vent hoses, one front and the other on the rear carb...if these are missing, as they sometimes are, that could be your source... scratch

    could also be...

    the bottom piece of the petcock where the hose connects is a press fit.

    take a block of wood and hammer(SFH) and give it a good tap ^up^

    my carbs weep from the main jet brass plugs... need to aneal the washers sometime.... but OTOH I like the smell of gas in the morning drunken .

    Mine does the same. My initial guess was that it was because the fuel was evaporating from the float bowls because the bike was hot. But, it still does it after sitting for several days without riding.
    I asked the same question on ROV right before the site wnet down and the most common answer I got was the possibility of a poor fuel cap vent or seal.

    Didn't you ask in another psot about having to use the choke when your bike is hot? If so, you may have a fuel system problem that either needs to be cleaned, sealed or adjusted.

    Didn't achmed fail his bomb making class?

    Saw a cartoon once. It was titled "suicide bombing class" and the instructor was standing around a whole group of recruits wearing a vest and holding a trigger in his hand. The caption said, "Now I'm only going to show you once how to do this".

    This is all great feedback. I had some time this evening to do a deeper inspection based on these ideas and I believe that they all checked out, but this exercise did prompt me to sniff my carburetors inch by inch. I think the problem might be my fuel filter. There isn't any leaking (it's all dry) but it does reek with fumes. Within the next few weeks, I'm going to replace it with a different brand see if the strong odor subsides. I may have gone too cheap.

    Thanks to all

    Upon second inspection, the gasoline smell is coming from the petcock right next to the filter. I expect that a rebuild kit should remedy this. naive?

    To repeat, the problem that I'm trying to solve is that the gasoline odor is so strong that I'm not able to store my RJ in the garage.

    The petcock is an easy rebuild. As a temporary measure, you can reverse the 4 hole rubber washer , (IE: front to back ) This part wears on the front and reversing it , in the majority of times will solve the problem .

    I noticed that since giving my carbs a thorough cleaning the other day because if a stuck float, I no longer have the gad odor in my garage. I think at that point, the float was stuck just enough to let a little gas spill over but not enough to let it drip out onto the gagage floor.
