1988 goofy idle

Postby GoldWingRev » Fri Nov 01, 2013 3:32 am



First off, I'm happy to be on this forum. I've learned so much about Wings--and I've only owned one since June (it's Nov. 1 2013 now).

I'm done with my problematic and solenoid-melting 1100. I picked up my 1500 today. It's an '88, only had one PO before it was traded for a Harley and ended up in a dealer near me. I got it on sale (winter is coming to the Midwest unfortunately). The bike is AMAZING. I picked it up in a heavy downpour, and a few miles away I gave it a bit of throttle and it fishtailed and I nearly went down. Gotta get used to the torque and let it start itself.

But, that's a problem. I noticed as I got my gear on that the idle seemed awfully high (keeping in mind it is a GoldWing, that's not much). I figured that because it had been sitting, if I put some fresh fuel into it and rode it, it would go down.

It hasn't. I put a full tank (actually 3 gallon) and rode 50 miles down the interstate from Milwaukee, and when I exited the tach was at 2K, and unlike my other Wing it actually was representative of the engine. It went down to 1K, but it still kept "hunting" for idle. Sounds like the choke was on (I quadruple checked--no).

At speed, there is nothing that I've noticed except the silky smooth engine and that it barely makes noise. Is there anything I should/could do? Should I just let the old gas run through (by my math, 3 gallons more) and see?

Thanks guys. There are struggling college kids who ride Wings, and I cannot tell you how invaluable information to me.

Happy Halloween.

The problem will not go away by itself if idle cannot be stabilized by idle adjusting knob to the right of fuel cap under flap. Remove air box and confirm choke linkage is working properly and enrichment rods are closing fully, then check cruise and throttle linkage is not binding holding RPM's up. Then check carb sync. You will then get into checking for vacuum leaks and carb troubles.

Considering that you just purchased the bike, have you considered taking it back to dealer and have them fix it?

Yeah, I was going go bring it back, but I'd like to have some knowledge of what it was just to sound better. I have a 30 day warranty and am not afraid of using it.

I forgot to add to the original post. When I fishtailed and saved the bike, it actually died, and wouldn't start until I turned it off and tried again. The engine wouldn't turn over. Is there some "over rev" built in that I'm not aware of? Maybe to prevent wheelspin?

I did not know about the idler adjuster screw until I read the manual last night, and apparently it's supposed to idle at 800 +\- 80. Right now it's idling at 1000 when it's behaving. Let me take a look at that adjuster when I get outside.

Leaky vac. lines and out of sync carbs are two of the possibilities...I know, just went through all of that.

As a dealer, I know he's supposed to check and adjust things as needed, or I can get him in trouble. Which I made especially clear to him...plus I have a 30 day warranty on it :-). I have been playing with the idle adjuster, and it seems to have worked. I'm gonna work through the last of the gas that has been in it and throw in some water remover and then ride it around some more.

Luckily the leg warmers work.

In reference to your favorite Wing pole.I've put about 8k on my 1800 that I got at the end of June(would have been more but I broke my wrist at the end of Sept)and I voted 1500.I've had at least one of each size of Wing(2-1200's) they've built so far and so far that is my favorite.There's a few things I like on the 1800,but like I said I voted 1500.If they sold a brand new 1500 as they are now with fuel injection I would take it in a heartbeat over the 1800.Now saying all that I haven't ridden a 2012/13,but IMHO the 1800 isn't all it was cracked up to be unless you're actually looking for more of a sport touring type bike.
If I'da known it would last this long,I'da taken better care of it.

When the bike died in the fishtail you probably activated the BAS "bank angle sensor".

Chris--thanks for voting. The 1500 is winning hands down on the poll, and I'm seeing why. I know the luggage on the 1500 holds more than the 1800 too (you can see by the shape, plus I think there's a CD changer in the new ones). It's great to hear that the model I chose is the best. I can get years out of mine then. All I've had to do is get used to the torque, which I looked up and compared to my 1100 (65 vs 110 ft/lbs). Amazing.

DingDong--thank you, that's exactly what it was. I wonder if mine was replaced by Honda....

Anyone else, if the idle problem is caused by vacuum leak, would rain affect it? Can I still ride or is it dangerous? I can bring it back on Monday if so--will be taking it to Milwaukee today so I can find out if I fixed it.

Now you know the BAS on your bike is working. If Honda replaced it there will be an X scribed into the frame on the lower right side. They can also tell you if it has been replaced by tracing the serial number.

I'll go take a look at the frame. It's a one owner bike, I'm hoping he did. I know there's some tests one can do to test as well.

Actually, it seems this question may have been resolved. I tweeted the idle adjuster (I think 800 RPMS is the small line below 1K, where it's supposed to idle; and I added some water remover and rode through a tank of gas. Now it behaves normally, so far as I can tell.

The BAS thing is new to me. I feel that if I did Deals Gap it would activate.

Please participate in my survey, good readers.

Deals Gap won't affect the BAS unless you lay her down.

Only way the bank angle sensor will activate is if there is lateral - sideways - movement of the rear end of the bike. Break the rear tire free from hard acceleration on a slick surface, it can kick out to one side. Let up on the throttle, it jumps back in line with the front wheel, this can be enough to trigger the bank angle sensor.

Never thought of it that way,but yeah I guess it could.I would've thought though that the weight/trigger/switch that actually moves around in the sensor being in a dense liquid(I forget just what)would act like a buffer in a case like you stated.What you're describing happens pretty fast,so I'm wondering if the BAS would react that fast.I thought when I read it that he thought it might kick in if he got leaned over far enough.

You're correct, the BAS has a damping fluid in it to prevent this. However, the early wings (like the one in question) had a defective unit where the fluid would leak/evaporate out, so a good jolt would be enough to activate it. There was (and still is) a recall on this item from Honda to fix it.
