Hey guys!
I got my GS500E going this past wednesday and she drove great!!! Had her up to 110 before backing off! Drove her home on the return trip from work she drove the same as going, just fine!
Then on my trip to work thurs night she died on me while riding her! Waited for 15 minutes she'd sart up, go well through the gears and about a mile or two she'd start losing power again! She dont just straight out die... she loses pwer then jerks forward with powrer then loses again and so on till she dies. Ican wait for 15 minutes and she starts up again then i go into the same thing!@!!!
Can someone help me?
I can pretty much be sure that it's a carb issue, but what?
I do have a inline filter and it's clean! (see thru type)

Do you have gas? (stupid question but...)
Could be a vaccume leak, try riding with the petcock on "PRI"
Could be a vaccume building up inside the tank, try riding with the gas cap open but not wide open. (just cracked open)
Could be dirt in the carbs.
Could be a dirty screen inside the tank.
Start somewhere and you'll find it. It took me a few months to figure out mine.

I'm guessing that its a fuel tank issue. there is an opening on the top of the tank that will relieve pressure as fuel is taken out of the tank. if it becomes blocked, fuel will stop coming out of the tank once the negative pressure in the tank overcomes the force of gravity taking the fuel out. Eventually, the pressure will re-equalize and the motor will run again and the cycle starts over.
Make sure you have fuel in the tank. Next time it happens, try opening the fuel tank. If you hear a hiss, and your bike starts right up again, you have found your problem. I know there is a post here about how to clean that vent out.

Man, the EXACT same thing was happenin to me. It'd run fine for a mile maybe, but then it'd start jerkin around and the throttle response sucked. I thought my floats were stuck or had some gunk in my fuel filter, but idiot me, I just needed some gas. :roll:

Ok, I'll try the tank trick out, but don't feel that is the issue. There is a gap between the cap and ring already so I can basically grag the key cover and pull up on it and it will log up and down about a 1/32 of an inch.
Checked out the float height by the hose trick..........and the right side, (sitting on it), is just under the gasket by 1/4 inch while the left side is at 1/2 inch under the gasket line.
I ran the bike the first day with the petcock valve lever, (long end at 12 o'clock), in the up position. Understand I was not to ride in the PRI position(nine o'clock).....am I wrong on that?
!/2 tank of gas in tank
When sitting and the petcock lever is on fuel (12 o'clock), I get gas dripping form the inlet face to the filter area. What could this be?

But THAT day shouldn't need to be TO-day. Read on....

Understand I was not to ride in the PRI position(nine o'clock).....am I wrong on that?There's nothing wrong with running in the PRIme position ... unless you have a leak somewhere, which it sounds like you do. :x
Quote from: josh28!/2 tank of gas in tankDon't you believe it! :nono: At least, not until you fill up and the tank takes 2.5 gallons or less. When I first got my GS I was fooled by the apparent fuel level in the tank, too. It looked like there was plenty, but I had to switch to PRIme until I finally filled up.
You didn't mention the model year, but you did say that you got a GS500E, which means 1989-2000. Since you're in TX I'll assume that the bike is a non-California model. Your tank should hold a total of 4.5 gallons, with a REServe of approximately 1 gallon. In other words, you should be able to burn 3.5 gallons with the fuel switch in the ON position before your bike does what you originally described and forces you to switch to REServe. Somewhere around 1/2 gallon later you will have to either switch to PRIme or push.

Wait a sec ... 1/2 inch under gasket and 1/4 inch under on the other one ... OK I am surprised it even ran ... its gotta be level wiht the gasket ... and if its under by 1-2mm that will be bad ... I set them both essentially equal ... but well under 1 mm diff is close enough IMHO ... and at gasket level.
The rest as kerry said. Yea leaks, gas level is deceptive cos the pickup is high in the tank not right at the bottom ... etc ...

Ok, Checked the gas, empty! But after getting more in her she ran for about five minutes and died out. :dunno:
Kerry, I'm in need of some fuel hose routing info:
With an aftermarket airfilter mounted (no air box) where would the propper routing of the houses be placed? It is fitted with a K&N double recepticle flter that is mounted to the carb inlet units directly. The hose connecting the twocarbs on the upper front side is not connected to anything....where does it need to go? Also noticed that my manual shows that the vacuum hoses are to connect to the canister..... ihave no hoses or canister! :dunno:
I'm going to get some pics for you to see tonight and try to get them to you ASAP! then you can SEE what I'm dealing with!

Hey Josh! Let's go through the pics one at a time:
1) Tank-mounted petcock (from the left side of the bike).
This looks fine. The REServe hose is on the left (in the front) and the ON hose is on the right (in the rear).
(http://www.bbburma.net/MiscFotos/GStwinMembers/josh28/100_0422_TankMountedPetcock.jpg)
2) Frame-mounted fuel selector switch (from the left side of the bike)
This also looks fine, except that the vacuum hose is not attached to the carbs. (We'll get to that in Picture #4.)
3) Entire fuel system
Everything looks almost perfect here:
4) Carburetor close-up (from the right side of the bike)
The arrow points to a vacuum takeoff. On all 3 of my pre-2001 bikes the vacuum hose from the fuel selector switch has been attached to the identical takeoff on the left carburetor. It probably doesn't matter(?) which carb the vacuum is taken from, but make sure that the unused takeoff is capped.
On 2001+ models, the vacuum hose IS attached to the right carb.
(http://www.bbburma.net/MiscFotos/GStwinMembers/josh28/100_0424_CarbsFromRight.jpg)
5) Carburetor close-up (from the front of the bike)
The section of coat hanger in the front is bent around the choke actuator rod (my term). Manipulating the choke lever pushes this rod from side to side and displaces both of the choke plungers. I can't tell from the photo whether or not the actuator rod is correctly attached to the plungers.
The hose attached to the top T-connector between the carbs does not connect to anything else. It is normally draped over the airbox and the open end is situated between the airbox and the battery box. (See the drawn diagram on the page that goat linked you to.) My understanding is that this hose provides "atmospheric reference pressure", which is what pushes fuel up out of the float bowls and through the jets when a partial vacuum is created by air flowing past the upper ends of the jets. The open end of the hose is tucked away in a "quiet" spot so that the reference pressure doesn't vary wildly with crosswinds or other turbulent air.
BTW, the two black rubber "towers" in this picture and the previous one are additional vacuum caps. To synchronize the carburetors you remove those caps, attach your carb synch tool to the vacuum takeoffs underneath them, and make adjustments by turning the spring-loaded Phillips-head screw between the carbs.
(http://www.bbburma.net/MiscFotos/GStwinMembers/josh28/100_0428_Carbs_Front.jpg)
6) and 7) K&N "Lunchbox" filter
I have no personal experience with this kind of filter, but it attaches to the rear of the carbs in place of the stock airbox. There should be a short vent hose which normally goes between the top of the valve cover and the stock airbox. When you replace the airbox with a lunchbox filter (or 2 separate "pod" filters) the airbox end of the vent hose should be capped with a one-way filter of some kind.
(http://www.bbburma.net/MiscFotos/GStwinMembers/josh28/100_0431_LunchboxFilter_ClosedEnd.jpg)
(http://www.bbburma.net/MiscFotos/GStwinMembers/josh28/100_0432_LunchboxFilter_OpenEnd.jpg)
One last note about the tank-mounted petcock that is circled in the diagram above. The hoses are drawn correctly (attached to the right inlets and outlets on the petcock and the fuel selector switch) but the petcock itself has been rotated 180 degrees. (That makes it very hard to turn the petcock ON and OFF!) If you use this diagram to route your hoses you need to know about this inaccuracy. Otherwise, since the filter inside the fuel tank is normally out-of-sight, you will "cross" the ON and REServe hoses. That means that if you ride with the fuel selector switch set to ON it will really pull from the lower REServe level inside the tank. And THAT means that when the bike starts coughing and you switch to REServe ... you will have already USED your reserve! :o
1) Tank-mounted petcock (from the left side of the bike).
This looks fine. The REServe hose is on the left (in the front) and the ON hose is on the right (in the rear).

2) Frame-mounted fuel selector switch (from the left side of the bike)
This also looks fine, except that the vacuum hose is not attached to the carbs. (We'll get to that in Picture #4.)
- * On the right (in the rear) is the REServe supply hose.
* On the left (in the front) from closest to farthest: ON supply hose, main fuel supply to the carbs, vacuum hose.[/list:u]Question: Is there a hose clamp of any kind on the vacuum hose? It's hard to tell from the photo.
3) Entire fuel system
Everything looks almost perfect here:
- * The hoses from the tank-mounted petcock to the frame-mounted Fuel Selector Switch are hooked up correctly.
* The hose with the (aftermarket) fuel filter seems to be hooked up correctly, too. (It should attach to the lower T-connector between the carbs.)
* BUT the vacuum line from the fuel selector switch is not attached. We'll talk about where that belongs with the next picture.[/list:u]

To let you know first off the choke acctuator rod does work fine.
It is the vaccum hoses that troubles me as well as how a normal taknk lock seal should look like? Mine has nothing to cousion it to stay tightly shut.
Also was wondering if the o-rings under the top caps of the carbs, if they where possibly not sealing would that make the bike do the "funky chicken dance" and die? :dunno:

Quote from: josh28
Pic #1 is of my own tank lock
Pic #2 is of the vacum hose that was rubbing the accelerator cable wire. I pulled the hose back to the fuel line and ziptied it there at the lower T to hold it in place. I thgink most of the vaccum hoses are preformed in an 90 degree angle at this area to avoid the cable from rubbing.
Pic #3 is after the hose is tied down and in place.
Pic #4 new vac hose in place. (3/16 vinyl hose)
Pic #5 is the new vaccum cap
Pic #6 is the fuel filter with new clamps added
Pic #7 is of entire engine compartment
Looking good! :thumb: (Well, except for the tank lock. And what happened to the frame on either side of the air filter? :o )
My only caution is to watch that vinyl hose over time. It's nice and stiff, which is good for a vacuum hose, but over a period of years it may become TOO stiff. Like any other type of hose I guess.... :roll:
Here is the vinyl hose that's been attached to my auxiliary fuel tank for 3 or 4 years:

Nope the stand is all the way up! After the bike seems to get warmed up and you end up in first gear, say at a stop sign or so, and you release the clutch (slowly of course) as usual, it seems as if the engine gets (I guess) too much gas and looses all power and just creeps foward till it dies itself out!
Still got a problem I believe with the floats.... I have gas on the left side (sitting on it) That is at a drop every 2-3 minutes from the carb,

don't think of it in terms of you letting out the clutch. what if it's in neutral, idling, and you twist the throttle. it dies, i'm assuming.
there's something wrong with your fuel system. the leaking carbs is a gasket failure most likely.
if it idles for awhile, does the engine speed raise? when i was running really lean, sometimes it would bog (never die) but the RPMs would climb with time (not good. over heating).
bogging down is definatly lean. have you ever messed with the mixture screws? (on the initial stock carb, you don't have access to the screws. they've got tabs to prevent tampering). i've never messed with any mods, but if you change your intake level, you need to change fuel accordingly.
have you run it on prime yet? if it still happens, then vaccum is not a problem. it's in your carbs somewhere.
