Stalling..HELP!

[fraze11]

ok, I have a new 09 GS500F with about 80k on it.  After its been warmed up when Im driving down the road in 5th doing about 80 or so the motor starts to bog down (while Im cruising along open throttle) and then as I keep maintaining throttle and speed it slowly starts to die.  I grab clutch and then it just stalls?!  WTF?  What could this be?  I have regular unleaded 87 octane gas (tank is half ful), I let it idle well before leaving, petcock is in ON.  After it does bog down and die, I wait about a min or so then it starts up and I take off, then about 5-7 min later it does it again.  In a 30min ride it did it 5 times.  If im leaving out important info please let me know.  Any advice or help appreciated.  Also, when its sitting idling its at about 1500rpm, is that idle rpms?  Thanks again for any help.

Your tank vent may be clogged, try opening the cap next time it happens to see if that is the case.

- fuel starvation: to test, set frame petcock to PRI.  Check inline filter and lines for deterioration or blockage.
- dirty carbs?

It's an 09 with 80k?  or 8k?

Thanks for the responses, I'm no mechanic but the symptoms do seem to be fuel related (as in not getting it after a bit).  The bike is a brand new 2009 with 81km's on it I've only had it 2 weeks so when I think dirty carbs, blocked filter I'm wondering how that could even be possible on a brand new bike. But I guess anything is possible.  When you say set the petcock to 'PRI' do you mean put it there and leave it there while driving?  When this happened to me after the bogging down and stalling, it starts up again and drives but only for about 5-7min then it does it again.  I even thought about draining the tank and putting in a fresh tank of gas (im still using the gas that was in it from the dealer when I got it)  and after searching this forum I thought even maybe adding some of this Sea Foam I've read about. 

Thanks again,

Where are the tank vent and inline filter located? is this something I can check and clear myself if needed??
Thanks.

If you just got it from a dealership I'd try to take it back to the dealership and tell them to fix it. I normally am completely against taking bikes to dealerships to get fixed, but if it's brand new you've gotta stick it to them. And don't drop it off and let them tell you they'll get to it in a couple days and call you when it's done. It's not normal maintenence so they should tell you when to bring it in and start working on it then.

Chances are it's something they could fix pretty quickly as it's almost certainly something between the gas tank to the carbs, and shouldn't be hard for someone experienced to figure out.

Thats my main option for sure...problem is...it wont stay running long enough for me to get it there (40min drive) and Im not exactly comfortable driving it in traffic if you know what I mean...so I'd need to borrow a truck or something to get it there.  Grrrrrrr....Im a bit agitated right now...I bought NEW to avoid this type of stuff that can happen when you buy used

When you say set the petcock to 'PRI' do you mean put it there and leave it there while driving?  When this happened to me after the bogging down and stalling, it starts up again and drives but only for about 5-7min then it does it again.  I even thought about draining the tank and putting in a fresh tank of gas (im still using the gas that was in it from the dealer when I got it)  and after searching this forum I thought even maybe adding some of this Sea Foam I've read about.

Fresh gas is a definite good thing to try.  Seafoam has never done anything for me; some dry gas or heet would be as effective.  Yes, you can try running on PRI while driving around.

Since getting it to the dealer is a problem, you might want to check the hoses (particularly the small one) going to the petcock.  It wouldn't surprse me that the dealer left something loose during assembly.

Thanks, before I take it in I'll try this *just in case* its that simple.  Sorry, one last thing; so when I'm in 'PRI' driving around how long should I leave it in that setting before putting it back to 'ON'?

You can leave it on PRI all day, won't hurt anything.  It's just gravity fed.  Someone correct me if I'm wrong, but it uses your reserve outlet, so you won't know when you're almost out of gas, but that's the only danger.

Regardless of what you find out or try, take it to the dealer and kick them until they fix it and you have a bike that runs correctly.

Just don't leave it on prime when you shut down/park.

There is a sequence of events that is possible (won't happen every time, but it's possible) when you do that that can lead to a cylinder full of liquid gas, leading to engine destruction when you try to crank it. "Hydrolock."

And 3rd or 4th to dang, it's brand new, you buy new, it should run right, or be made to run right at no further cost to you by the dealer. Including them picking it up in a truck, if needed. But if you can ride it there on prime, that's fine too.

The tank vent is in the gas cap. Details here: http://gstwins.com/gsboard/index.php?topic=41061.0

There may not be an inline filter (it's not stock, as far as I know, unless Suzuki started putting them on recently) - it would be on the fuel line between the frame petcock and the carbs, if one had been added. There is a screen on the tank petcock, inside the tank, and that's it for stock filtering as far as I know (not much of a filter, it really is a screen).

And yes, prime draws from reserve, so be sure you have enough fuel.

See, you got such a good deal that it couldn't be true?! Sorry to hear this, not god at all.  As mentioned go to the stealership and have them take care of it.  That is ridiculous in my opinion and should not happen.

Heh..I was starting to think that  .  Its not that I'm not worried as I'm sure it something relatively simple, its the frustration and aggrivation of it all thats complete ballz.  Thanks again for all the input tho, this forum will surely be a place I frequent for advice and tips

[fraze11]

In case anyone was interested;  I just got off the phone with the dealer where I bought it, after describing the issue I got the typical "Hmmm, thats odd never heard of that before" response ... and then they asked their mechanic and he told me to "Drive around with it in the PRI or the RES position, if it still does it bring it in" ... so thats that then.  Its going back in.

You may not have an inline filter, and your tank filter or hoses may be clogged.  If they want to reem you with prices, then I say pull all your hoses off and see if any are clogged.  If one is clogged (im guessing if one is clogged its gonna be the one going to the carbs if the problem happens no matter where the pet chicken is set) go buy a length of hose and an inline filter like this for 1.79 or whatever and put it in the middle of the hose you just bought.

All that is if your hose is clogged.  If none of your hoses are clogged then your tank petcock (not the 3 position lever you can see) may be clogged.  Your tank petcock is underneath the right side of the tank. theres two posistions. on and off.  If the slot is straight up and down, the tank petcock is on.  to check to see if this is clogged you could leave the tank on, and pull the hoses off the frame petcock.  the hose on the right side is the reserve line, and the hose on the left side that is the on line. (there are two hoses on the left, make sure you pull the one that is not attached to the carbs.  Also, when I say pull these hoses, I mean only pull them off the frame petcock but leave them on the tank. now, let the gas pour out of one into a bucket while holding your thumb over the other, or clamping it shut with some hose clamps. so the same for the other hose.  If the gas is pouring out slow for one of them, then the filter is clogged.  if the filter is clogged pull the tank, flip it over and undo the two screws that hold the petcock on and it will slide right out

My guess is that you are out of gas, looking in it does NOT tell you if there is enough to keep it running after standing it upright off the sidestand.

Put gas in it and try it before doing anything else.

After that you can figure out if your reserve is hooked up properly, or if there is actually a problem somewhere.

Wot Jim said...

Put in res, ride to gas station and fill right up on center stand. Don't know how to put on center stand? Then fill while on side stand until bottom of fill sleeve. THEN, reset your trip meter to Zero. Put back to On and ride. See how it goes.

Dealers are Notorious for giving you stuff all gas. First stop should always be gas station on way home.

Do this first. Then report back your findings.

I have found BP gas does the best in my bike. Shell is terrible. I use 95 octane or 91. I also have a K9. No probs in close to 19,000 kms now. Try the above first. Let us know, then.

The problem is with the petcock, i'm 100% certain of it.  I had the same problem.  Choices are either ride around in 'RES'(not prime) or you can grind off the little metal tab that prevents the knob from being turned all the way around.  If you take the petcock apart and look at how it lines up on the different settings you'll see that taking that tab out gives you fuel from the 'ON' setting(just by a different path through the valve) while allowing you to keep your 'RES' setting for just that.

Like others have said. YOU ARE OUT OF FUEL!!!!! Its a new bike.  You see gas in there, but the pick-up for the main line is above the fuel at times while riding,I have done it 3 or 4 times and once towed my bike home. when i put gas in it, she ran. I get 80 miles before i fill up or your symptoms happen to me Even though there is enough fuel for the reserve pick up to be under, I still fill up at every 80 miles. How many miles have you ridden and how many on the odometer? Chances are if its 100 or more miles, and you don't know how much fuel the dealer put in then, YOUR OUT OF FUEL! Always check the simple things first, like when a lamp doesn't work you look to see if its plugged in before changing the lightbulb, right?
