Ran outta gas again, this time I had the fuel petcock in the opposite position and when she started sputtering I flipped it over, but to no avail, after I pushed her into a nearby fuel station and gassed her up she took 3.5 gals. of fuel again.
HMMMMMMM, now what?
And sorry Canyon wasn't around to take pics this time.

upwards and I flipped it down, but last time when me and Canyon was riding I had it down and flipped it up and it didn't work that way either, one of these positions has to be the correct one, I would think.

If you only put in about a quart of fuel on an empty tank, and have the valve on reserve does the fuel come out? - With a hose going into a container.
Than as its running out and you flip to main tank does it stop the flow, until you flip back to reserve?
Just a quick test to see if the valve is controlling.

Sounds like you had it on reserve. I wonder if someone reversed the petcock handle?

thanx swifty I will have to do that tomorrow and see, I will drain the tank and check that out. how hard is it to change one of these valves, cost? thats the next step I guess, but I am why it would drain the tank in both positions? it took 3.5 gals. both times.

One would think that at first but like I said I had it in the downward position and I believe that that is in the reserve position, so I figured my bad, but then I put 3.5 gals. in her and turn it upwards and she burns 3.5 gals. again and when I flip her down the tank is empty.

If it is system with 2 pipes of different heights maybe one has rusted off or damaged previously. My bike has a different system, but I have seen photos of the pipe with a filter attached to it.

I'll have to take a pic tomorrow and post it, only have 75 miles on this tank so far, so probably still have about a half tank of fuel still in there, maybe when I get to 100 miles on it I will look into draining it then, probably by the weekend, we are getting alotta rain here in Fla. this week

huh?

You had it in the reserve position. All the way clockwise is reserve and fully counterclockwise is on. You can not put the lever on wrong.
I guess yes I did have it in the reserve position once, but it ran dry in both positions, I don't think it was put on wrong I just wonder why it's working wrong. Did I have it in the reserve position when it was up or down, cause it burn a full 3.5 gallons of fuel in both positions, You say the only problem is that when it was up it was in reserve and when it was down it was in reserve? so which way is not reserve?

The petcock on my 07 is "on" at 3 o'clock, "off" at 6 o'clock, and "res" at 9 o'clock. Is the pick-up broken off of yours? I would have thought yours would have been similar to mine.

I have 3 settings one at 6:00, one at 9:00 and one at 12:00, I know 9:00 is the off position and I ran outta fuel twice now, once when I was in the 12:00 position and once when I was in the 6:00 position. So I am assuming something is wrong. I just dont know if it's in the fuel tank or it's the petcock valve itself I guess. Both times in the 12:00 and 6:00 positions when I refueled it took 3.5 gallons of fuel, pretty much used the whole tank if I am correct these have a 3.5 gallon fuel tank capacity.

Well, I'd think it was your petcock. Your tank is doing what it's suppose to. Holds 3.5 gal and runs out when mt. ;)

I think I would check the petcock operation with this tankful...
You have 75 miles on it now...
Ride until you reach 100 miles...
> I`m going on looking at the avatar pic of your Bike looking like my 750 ACE, and I switch to reserve anywhere from 108- 140 miles, depending on fill level <

At 100 miles, Switch knob forward/front of the Bike to 9o`clock/OFF, remove the fuel line, attach a hose to the petcock switch Down to 6o`clock, drain into a container...

>My petcock leaks while in the OFF position, be aware of this problem<

At this position you SHOULD empty the ON portion of fuel in the tank, which should be a small amount...
After the fuel stops flowing, empty the container...
Switch UP to 12o`clock/RES position...

Does fuel flow now?
IF so, empty the RES portion of the tank into the container...
Measure your fuel with a measuring device...
I use a marked feed bucket, baby bottles / OR IF you`re brave and reckless, swipe the wifes large measuring cup from the kitchen :D

Now that you have emptied the fuel from your tank, and know whether the petcock is working correctly, then proceed to remove the petcock from the tank, investigate and clean the petcock screen...


Free advice!!!

Lets RIDE!
BUT NOT run outta fuel;)

IF I had this problem, I think I might be temped to carry a quart of fuel in the saddlebag,

^^^^^+1. I think smilie has it right. Sounds like the main (not reserve) pickup is broken off. It would be the one that sits higher in the tank.

I have always used my trip odometer for a fuel gauge and never relied on reserve or the low fuel light. Just sayin.
