high idle

[jacob_ns]

He may have chosen the entirely wrong way to approach the subject, but I completely agree with BeerGoggled.

I've seen many incorrect diagnosis from members who haven't the slightest clue as to why they're suggesting what they are, save for mimicing past responses from others on similar matters. That doesn't mean people shouldn't be responding, but when you have to preface your post with "I'm probably wrong but..." you should think twice about hitting submit.

That said, there are many others who are completely and utterly filled to their hats with GS500 knowledge, information and suggestions on maintenance due to their past experiences and their technical know-how and ability. Those are the people who should be key players in tech diagnosis.

Ive never been much for sugar coating the truth. After being a member of several different forums dating back 8 years or so,  Ive learned over that time a thick skin should be a login requirement.


OP , sorry for the hijack and drama.  Im done.

and I owe beergoggles an apology so here it is - my statement that you were ignorant was out of line.

If the revs are staying up after you've closed the throttle, you may have "hanging idle," i.e., the motor keeps running at 3k-4k RPMs for a few seconds after the throttle is closed.  Mrs.'s GS started doing that after about 400 miles.  Very irritating in general but especially when doing mountain twisties!

Easy fix, though:  warm the moto up thoroughly, then use the idle knob (behind the carbs, over the transmission, but beware, it's HOT back there) and set the RPMs to around 1200.  If it still hangs, dial down, and if it wants to stall dial up.  Took me around 20 minutes to get it right.

Exactly what I did on mine .... fixed the issue, 4,000km later still perfect.

The fluff replies in this forum astounds me. If you dont know what youre talking about dont type drivile and hit "post"!...its simple really.

To the original poster: what youre describing is "hanging idle". To cure it without guesses and "it might be this"...

1st, adjust the valves to spec. (or have your shop do it)
2nd,  have the carbs cleaned and rejetted (or have your shop do it) to pilot:  http://cgi.ebay.com/ebaymotors/_W0QQcmdZViewItemQQitemZ170574271909

3rd, re-syncronize the carbs.(or....you guessed it....have your shop do it)
....after this, you'll have a correctly running GS unless theres vacuum leaks which your shop should have found/corrected during the clean/rejet/re-sync


I dont mean to come across like a prick but, after searching countless threads /sites and never getting a deffinitive answer to a decade old problem, I get tired of reading these vague and unknowledgeable replies.   I figured this out on my own and my wifes bike now runs better than it did from the factory, Im sure.



....let the flaming begin.....

Funny, I'm having the same issues as the author I've done everything everyone has recommended. I still have a hanging idle and short of just getting a different set of carbs there has not been any useful information on here in quite some time. The poster should always take into account that the info they get on here is probably just as good as just typing it in the search engine bing google whatever they like. The info would probably be just as good. I'm pretty much to the point that I don't put much faith into what people say here unless they can show me certification that this is what they specialize in. Typical easy maintainance stuff sure it is okay but no way can any certain diagnostics can be given here and the quality info has really been circling the toilet as of late. You tell people your experience or whatever it turns into a "don't tell me what to do your not my mom" krap. I miss the old days when we had capable adults on here and you would get useful info.

To be frank the more people "claim" they know about things the less I actually believe them.

To the author if you find out what is actually wrong let me know so I can try it. Can't be worse than some of the advice you can get on the interwebs.

I had a hanging idle too. The advice on this forum was great. It helped me, combined with what knowledge I have of motorcycles, solve the problem without ever having to remove the carbs. They're due for a real cleaning soon and I'll be stripping them down, rejetting them, cleaning  them, and reinstalling them when I get the jardine exhaust this winter.

The truth is, I've gathered, hanging idle is a symptom that manifests itself when a number of things are wrong. The fuel circuit a bit wonky? Hanging idle. Valves stuck/misadjusted? Hanging idle. Exhaust leak? Hanging idle. Something ever-so-slightly misaligned inside a carb? Hanging idle. Stickly throttle cables/choke? Hanging idle. Misadjusted idle screw? Hanging idle. Misadjusted mixture screw? Hanging idle. This was my problem. I literally checked everything. The forum literally advised everything. 4 oz. of B12 just so happened to be the "fix-in-a-can" that I needed so I could put off rejetting/cleaning until I had a reason to take the carbs off. If you ask such a general question you're bound to get the lion's share of general answers. Deal with it. Or you could take it to your local highway robbers and pay them 75 an hour to find the problem. They're "certified". They'll fix it. They'll also make sure you won't be able to pay the bills this month. Complaining about free advice is utterly pointless. A mechanic would give you the same list of generic answers AND charge you for it!

Uhm, well being that it was the bikes only symptom how is it a general question? When a patient came to me and said "I have shortness of breath" I wouldn't tell them "hey that's a general symptom come back until you've got more so it is easier for me to figure it out". As they say time is money and at this point we are at what like 4 months trying to diagnose this problem of mine  During this time I've had to replace a valve gasket from taking it off and on not to mention the oil leak all over my riding pants, replacement of fuel lines from taking it off and on, had to replace the petcock during this time could be from all the removals or just time I don't even know, or when the Buddha didn't see the picture I was refering to and was told to cap it off ended up with an airbox full of gas, and the torn ligament in my right arm when the tank rocked off of it's stand when the cat hit it. So, I would dare to say if I just took it to my local guy the first time I even had a symptom I'd probaly be ahead. But, alas I followed the "not so free advice" because I sure as hell have spent alot of time and money parts/ Dr on this. I hope like hell this last time I put the tank on it will run almost decently.

As far as calling all mechanics crooks I hate sterotyping more than anything in the world. The guys at the motorcycle clinic have been as helpful as anyone can be without taking it apart. They told me $170 and they would do a full tune up and check over of my bike. For $75 I could just bring the carbs in and they would have them singing. Unfortunately, when one is disabled $75 is alot of money. I already have to choose between medication and food some weeks.

But, I think I have a bit of an idea what might be going on that no one caught here. I got a K&N drop in which is like stock I thought but I wouldn't have to replace. So, one of the jets might be off. But, I'm not sure because this bike was doing it before that.

If it makes you feel any better my hanging idle has returned. I've dialed it in to be almost 80% sure that it's a pilot circuit issue. One of my pilot jets is probably seriously clogged, or my float bowls are so dirty the B12 managed to clean the jet, but the stuff at the bottom of the bowl remained. Heat causes the varnish to become pliable and lodge itself in the pilot circuit. These bikes are naturally lean, and anything causing the mixture to lean out even a little bit more will hang the idle hard. It's fairly apparent that because it occurs only after 30 or so minutes of riding hard that it's not a vacuum leak. I've already ran the WD40 test after a long ride with the idle hanging and nothing gets sucked in.

As such, I've ordered a jet kit from Buddha and by November I'll have my exhaust kit and filter and hopefully that weekend I'll have them tuned and ready to go. The mix with richen up and the jets will be clean so it should run fine.



Not all mechanics are crooks. Only the ones who went to school for it. You know, the guy at the dealership. I'm sorry to hear about all your injuries, but everything except the cat attempting to kill you is part of working on a bike. I've had molten oil spilled on me, I've burned myself checking exhaust pipes and working on warm bikes. From all that I've learned to always wear throw away clothes when working on oil, and don't wear your nice Mechanix gloves when you're working with parts that could leak (or are designed to). It's a part of learning, and half the fun of working on the bike (to me).

first take it for a good long ride... 20-30 mins of twisties or just be a little rough with it, get the engine up to full operating temp, adjust idle to 1000-1100 and this could fix the issue, also check to make sure the 2 brass plugs are still on your mix screws.

if that does not work spray some ether through your pilot circuits... this can sometimes clean some gunk out.

if all else fails rebuild the carb, pull the jets sync and reinstall...

if that doesn't help over fill the gas tank and light a match... (dont really do this)
