Out of gas, but i shouldnt be.

On the way home from my ride today my bike started pulling funny, kind of like it was getting power then letting off then repeating. I wasnt moving the throttle, and i SHOULD have had plenty of gas left to get me home. Well suddenly i loose power and im coasting. downshift downshift downshift, i go from about 80 to 25 and see a cop w/ his lights on up ahead. i turn my reserve on, because i knew the symptoms were i was short on gas. but from what my trip counter was telling me i had at least 50 miles left before i'd even think of hitting reserve.


So i stop the bike. give it a few minutes, check for leaks, etc etc etc. Everything seems fine. only thing different i could possibly fathom was i was idling a bit too high, around 1500-1600... easily fixxed though, that couldnt be it.

I got back on the highway (w/ reserve on) and made it home the next 35-40 miles A-okay, no problems. didnt do any fast accelerating, nothing fancy, just wanted to get home and not be stranded.

Well about 4 blocks from my house i turn off the main road and start headin home. i got to give it some gas and it is lagging, bad... like real bad. like i opened up the throttle all the way and nothing.

again i suspect i have run out of gas. its is the obvious solution. but once again i should not BE out of gas. i even pop the lid and i can see gas down there, and i still have my reserve on.



Well this morning i found a little hose dangling under my swingarm by my exhaust. i'd never noticed it before, but it the bike ran fine, responded fine, so i figured it was just something i had over looked. I over filled my tank a little bit and noticed the tube when gas came out of it and leaked a little on my hot exhaust, causing smoke.



I'm starting to think that little guy shouldn't be hanging out there. can anybody shed some light on the situation? here are pics of the aforementioned hangy tube and a shot of my tank, showing there is obviousl gas in there.

its drewp~ when ran out of gas on my buddies f3 the reserve was not working, it was like the reserve filter was clogged and not allowing any of the gas that was there to used, i knew it had enough gas, but it still wasnt getting any, is there any places that look like they are missing a tube or hose?

what irks me though, is if it was the filter being clogged on the reserve line, then the bike wouldnt have acted like it was running out of gas early... it simply would have not used the reserve line. I still made it about 40 miles on reserve.

i didnt really have a chance to get up inside the poor thing. Or even look too closely inside the gas tank.

I think this is gonna be my excuse to finally rip the gas tank off...

I really wanna know WTF IS THAT TUBE.

that tube is a overfill tube mostly, Check your fuel filter on the bike if it's clogged replace it.. because it will kill your fuelpump(fuel injection) I think if it's carbs it's just a gravity fed(im not 100% sure) or else little "fuel pumps' in the carbs.

But yes, first place i would check is fuel filter.. and if you have never replaced it.. and it's not clogged replace it any way.

k. fuel filter. wouldnt it have to be super clogged to have this sort of problem? I was riding fine all day, just happened after about 60 miles of highway riding (about 75-85mph)

Should i go w/ an OEM filter or aftermarket?

either/or

Well if it's restricting fuel.. it's gona run like ****.. it's possible you got bad gas and it finally got sucked in, if it's carbed, and it's gravity fed..there is no preasure, and not enough gas gets by the fuel filter witch causes it to run like crap. and not even start.

it definatly goes up towards the gas tank... it gets lost in the machinery above the swing arm.

Man all that is, is a overflow tube.
When you over fill the tank and it gets around the lip and goes in a hole....that hole is conneceted to that hose.

My F3 would do this from time to time.. You may have just eatin fuel like it was your job that day. No sweat, tomarrow is another day and another kick in balls from the gas company. Just see what happens on the next tank.
