    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Ok here are some questions for you that I am sure have been asked a hundred times.
First off this is my bike, a 1981 Suzuki GS1000GL. If I work at it I can get it to start, with a rough idle. Cannot give it any throttle or it will die out (start to rev first then sputter and die). Now it acts like fuel starving, but has fuel spitting out of the carbs.
Now a little more about the bike. It sat torn apart for a few years before a friend of mine bought it a year ago. Now we have worked on it from time to time then last fall he said it would not tart at all. We had it running (kinda) it would do 70 with no problems, any faster it would fall on its face. I tore the pet cock apart cleaned it out and made sure it had good fuel flow there. I replaced the fuel and vacuum lines. I took the carbs apart and cleaned them out, had a lot of white residue in the bowls. It does have an aftermarket exhaust on it that I do not much care for, just to loud.
Now for me this is kinda a flashback as my first street bike was a GS550L. This one is very similar with the same look and stance. This is also my "little red sports car" as my wife calls it.
So with all said any ideas or things to look at will be welcomed. Any questions for me, just ask. Thank You, Shaun
 
Just an update: It will now idle with full choke, at about 3000rpm. After a few minutes the choke will pull itself off and then you can give it some throttle. Took it around town just a bit, did ok but have to yank the choke out to get going from a stop sign. Will continue to work on it. Shaun
 
Shaun,

Go thru the Megawelcome and completely clean the carbs

It sounds like they are still clogged, plus you'll need a jet kit for that header
 
Your pilot jets are clogged. You need to do a strip and clean of the carbs. Check out the tutorials.
 
Should have read that first. Thank you for the input. I did read through the tutorial. Fantastic information. I did clean out the carbs again, did not soak but did give a thorough cleaning. It runs ok now. At least you can control the throttle now. Took it out on the highway and it did good. A little sluggish at first but was still an enjoyable ride. Seems the more it runs the better it runs, but I have seen that before. Thanks again, Shaun
 
Actually since its "spitting fuel " I would surmise the pilot jets are not clogged...rather they are missing the rubber plugs over them and they are simply flooding out.

If the pilot jets were clogged they wouldnt be spewing fuel like he says they are. least thats my opinion anyway.
 
Spitting fuel out where? It will only idle with choke on, that tells me it isn't over rich or flooding. Sounds like the spitting fuel is not going into the engine to me.

The O Rings were bad between the intake boots and the engine. I believe that is what was causing some of the problems. Another problem is, well no easy way to admit this, me. By skipping the soak I believe that I loosened up some gunk that has now traveled into the main jets. I will be doing a complete tear down of the carbs and will include the soak this time. There is a charging issue as well and will have to address this before going to far. Seems to be running at least in art from the battery and not recharging it at all.
For any new guys reading this, learn from my mistake. Taking shortcuts will just cost you more in the end. Shaun
 
Check the Newbie Mistakes thread linked in my signature so you know about some of the more common problems.
 
Well my kits are on the way. My carbs are soaking (one at a time) and I found the problem with my charging system, I think. Now I have replaced my fuel petcock, fuel line, will have rebuilt carbs, new O-rings, new air filter and a new battery. I have also changed the plugs, plug wires and oil. Actually I did the oil change plugs and wires right off the bat to eliminate those from possible problems.
I think I will be able to ride her soon, I hope. It does have a minor leak at the tensioner, pretty common leak I think. I am also still looking for a stock set of pipes for it as well, this one is just to loud for me. LOL, anyone want to trade a V&H 4 into 1 pipe for a stock one? And when I get it figured out I will post a picture as well. Shaun
