2005 Rough Idle on hot start

[bthacker]

I am having a strange problem and wonder if anyone else has experanced this. On cold start everything is fine. I can ride for about 1 hour, pull over to get a drink and/or rest, get back on bike, start it up and it will idle rough, not want to take fuel. When you rev it, it will rev then RPM will fall to almost 0, motor will almost quit of a few times it has quit. If it don't quit it will return to a below normal idle. I can ride it for just a few miles and it will act alright. It will idel normal at normal idle RPM. It does not do it everytime but is getting worse. I tried changing the plugs, cleaning the airfilter. No help. The bike has around 28,000 miles and is a 2005 model. Just wondering if anyone has experanced this problem or has any insight on what the cause could be.
By the way the F1 light does not indicate a problem. It comes on with the key for about 3 seconds and goes out like normal. Have owned the bike sense new and has had better than normal service.
Any advice?

Have you ever changed your fuel filter ?

I have taken the fuel filter out and blew air threw it and it seemed to be clean.

To be safe, I would change the fuel filter.Do a search on this site on " Emgo " fuel filters. NO GOOD !!
All filters are not the same, just don't replace with any kind.

Looking at this again the fuel filter I blew air threw was on the pickup tube in the tank, is their another fuel filter? If so where is it located?
Thank You

On the 1800 there is no fuel filter. When you replaced your plugs what did you set the gap at, and have you run any injector cleaner through the system also? It sounds like you possibly need to run some Seafoam or Techron in your tank and give the injectors and fuel system a good cleaning to start with.

No fuel filter, not even in the fuel tank pump kit " Really " ?
If there is one in there, I see it must not be a easy task to get at.

The 1800 doesnt have filters like the 1200 or 1500 at all. My guess is with the size of the injectors it probably doesnt need it.

It has a screen on the pickup on the fuel pump. I have ran seafoam once but think I may need to run a few tanks threw it with seafoam. Not too long ago I was riding with our group and we stopped and got gas. Several complained about running bad including me. I seamed to have got a lot of bad gas latley. I am also starting to watch where I get gas. I am now looking for stations that have a hose for each grade of fuel. I got thinking about it and how much fuel is in the hose and pump before the switching valve in the unit. I think I may be getting mostly what the person that pumped before me got. I would think that the hose it's self would hold 1 gallon and maybe the switching/pump system would hold a gallon so right their I would be getting 2 gallons of regular when paying for the good stuff. That means that if I am topping off before a ride I may only get 2 or 3 gallons, not enough to get top grade to my tank. Any thoughts?

I also get fuel at a station with a stand alone pump for premium fuel for the same reason, I am paying for somone else's reqular fuel that was left in the pump hose etc. keep the sea foam flowing and see what happens

That is what I am doing, keeping the seafoam in it. I have not gotten to ride much latley but willbe this weekend.

Have you tried resetting the ECM?

[bthacker]

If you mean starting the bike and letting it idle until the fan kicks on and then turn it off, I done that last night but have not drove it sense.
Is this what you mean? If not tell me how to perform this.

Yes, that is what I am referring to. Also (and you probably know) you don't touch the throttle at any time during this process. Also, I will say that I have had some of these symptoms you describe from day one with no miles on the odo. If the bike is turned off after warming up, say to go into a gas station for a few minutes, then it feels like I have to give it more throttle than I should to keep from killing the engine when releasing the clutch. This doesn't happen all the time but I don't really pay attention that much anymore.

You decribe what I am experancing. Mine has acted like that from time to time for the last 3 or 4 years but recently got worse. I think I had some junk in the injectors, I know I have gotten some bad gas at one stop and with the crap for gas that is out there I know I will get more. I have been running seafoam in two tanks, ran out of seafoam went to fill up and bought a bottle of STP injector cleaner and put in it, so 3 tanks of cleaner ran through it. I think I am going to start putting seafoam in it once a month. I just went on a camping trip this weekend for 3 days and two nights up on the Blue Ridge Parkway, ( Don't ask, it rained the whole weekend, and thought a new tent would not leak. Have everything hung up drying out) it only happend once to me that I can remember the whole weekend so I hope it is back to normal with it happening only once in a while. I pulled a traler and would have surely noticed it pulling out. This is also after the reset and that could have also helped it. I don't know what fixed it but glad it is back to normal. Thank You all for your help.

Last time I rode the BRP it rained on us every day.

[bthacker]

Cannot get it to rain at the house, grass dying but let me get on the bike and it will follow me around.

I got back from Deals Gap in late August just before the rain fronts started coming in along the eastern seaboard.

For what your are describing I experienced the same after filling my tank. This I attributed to the different types, blends of fuel. When I got home I put SeaFoam in a couple of tanks to clean the system out and have not experienced any repeats since. SeaFoam is great. I use it in everything from my car to snow blower.

Yea, I used seafoam in a couple of tanks and I think it has cleared it up for now. Good stuff.

Hi I'm brand new, just joined a few days ago, I just a couple weeks ago bought a 2006 GL1800 Goldwing with 35000 miles and I'm having the same problem, sometimes when it's cold but mostly after it warms up, I have almost dumped the bike several times due to this, just the other day I missed a turn and had to make a U turn to the left and when I gave it the gas it almost shut off and when this happened I slammed my left foot down on the pavement almost breaking my foot, still sore as a matter of fact, but so much for my foot it will heal but yet to figure out what's causing the bike to act this way, a couple times it has shut off as if you turned the switch off, so far very disappointed in the bike due to this, I just talked to Long shore cycles in Florence Al the told they have heard of this only a couple times but did say fuel treatment with injector cleaner may be the answer, I will try this to see if it helps out, also the engine or the trans makes a strange whining noise, and it's almost like there is slack in the trans and makes noise when I give it gas and then let off, hope this in normal for Goldwing's, and I did not buy someone else's problems. Oh I hope you and your bike are doing fine and your having no more problems, maybe you can reply and let me know,
Thanks

[Pam]

I get the whine too while putting the power to it almost like an old grain truckk under heavy load I believe this is a normal thing for the 1800, I give mine a splash of sea foam a couple of times a summer and have had no issues but I try to buy fuel at stations with out the multi grade pump for the reasons already mentioned

[liflyboy]

2 things.
1) the U-turn, and ANY slow manoeuvres should be performed with the throttle open to a steady 1500 - 2000 RPM, and control the speed with the clutch and rear brake.
2) I've always heard that the only impact of putting anything but "regular" gas in a Goldwing it to your wallet. I've always used regular (87) and it's always been fine.
