Idle surging

Postby Algie1100 » Sun May 22, 2016 9:41 am



Hello

New member here, just purchased a 97 SE. During the test ride I didn't notice any surging at idle but after a 50 mile ride home it was surging at bit in my driveway. I've read a bunch of posts on the issue and will get it sorted out, my question is in the meantime is it hurting anything to keep riding it as is? What are some of the negatives?
Thanks
Al

Try Seafoam, first. Mine did the same when I first got it. Seafoam in the gas, maybe a half can to a tank for the first try, may clear it up. I use an ounce or 2 with every fillup, and haven't had a reoccurrance since. First time, try to do a fair amount of idling, as opposed to highway mileage. It's the idle circuits you need to clean out. Treat again, if the first tank doesn't do it.
Otherwise, it could be a vacuum leak, or I've read about a temp sensor that can also cause issues. But, try the simple first.
Your question. I can't see it hurting anything. Just annoying.

The first and simplest thing to do is play with the idle adjustment knob/cable. Make sure it's freed up and turn it out until the idle is low or the engine dies, then idle it back up to normal. That will cure a surging idle sometimes.

I have had two wings, an 89 and a 98 both with the surging problem. It was more evident in cold weather below 40 degrees. There is a 3/16 inch vacuum hose connecting the intake bores, at the rear of the intake bores beneath the rubber dust cover. That tube cracks through on the left side in the elbow of the vacuum tube. The carbs need to be pulled to access this tube for replacement. Tube is still available through Honda for $8.50. All 1500 wings will or do have this problem. Not the easiest to get to but it is the cure to the surging. If the bike is to be taken in for the problem, ask to talk to the most qualified wing tech and see if they know about this problem. Most do not! They want to rebuild the carbs or some other darn expensive uneeded work. EGJ

Thanks for all the replies. With my luck it will require pulling the carbs, but as long is it's not hurting anything I'll wait till Fall to do anything about it.

In all basics it sounds like it was running good then petered out a little. That pretty much says it's fuel related.
NIP IT in the bud and try the "mechanic in a can" approach first.
As others said, Seafoam. It's tried and true.
Your location: Seattle WA. If it sat a while, the gas might have condensation, use some yellow bottle HEET.
When ethKRAPanol sits, it separates and clogs/gums up little orifices. Seafoam or see below.

IF your mechanically handy:
Replace the fuel filter and fill it with Gumout Carb-Cleaner (never the cheaper brands) and install. Go for a close to home ride and in about 3 miles you'll feel when that cleaner hits the carbs, it's noticable.
That shot of carb-cleaner did the trick in my Wing last year when it was surging.

GOOD LUCK

Costs you nothing and takes a few minutes.
It worked for my 89.

Read the post regarding the idle fix - it involves plugging the idle air jets with toothpicks - it works and is an easy fix that will cause no harm.

I Had the same problem with my 96 1500.

I found a cracked vacuum pipe on the carb control unit mounted just beside the top right hand frame rail. There is a tight bend in the pipe and it cracked right on the bend. I replaced the cracked piece using some pipe I had and a small metal joiner inside the hose.
Bike runs great now.

Dont think it will do any harm anyway. Might run a bit lean.

Good luck with the bike.

Ok, Algie1100, it's been a week and a half. What's up with the surging? :evil:

Unfortunately right now the bike is sitting in my garage in Arizona and I'm in Washington. I plan on flying down and riding it back later this month. I was mostly concerned that riding it with the idle surge could cause issues on the ride back. I'll try all the quick fixes before I leave, but won't have time to tear into it till I get home.
Thanks for all the suggestions.

Adding a few pictures of the new bike. My last bike was a 05 Goldwing that met an unfortunate demise with a deer last summer. We broadsided a full grown deer at highway speed, but I managed to keep the bike upright and was able to ride the bike home, but it destroyed every piece of plastic in the front of the bike and was declared a total loss. My wife says she will never ride on the back of anything other than a GW now. Hoping I will like the 1500 as much as I did the 1800.
