Question about Harley Davidson FLHRCI Road King Classic Motorcycles

1 Answer

1998 road king fuel injected seems like after 150-200 miles the bike does not want to idle and kills. I can get it it to start but have to keep the throttle up to keep it running even when shifting. Black smoke comes out untill I start getting it to go. It will stay running without a problem again even for hundreds of miles until I have to downshift or eventually have to stop.

So the problem only occurs at idle. For some reason the injection is allowing too much fuel at idle. That explains the black smoke. At highway speed the engine needs the fuel but at idle it should have a lot less fuel so it loads up and blows black.

You may have one injector that doesn't seat fully so it dumps too much gas at idle. Try some brand of injection cleaner you can trust in your bike and see if that fixes it. If not, you better get it in to the dealer because it will be dumping contaminants into the engine oil.

SOURCE: carbs were removed and cleaned. now starts hard and does not idle

sounds like carbs not cleaned right, oh try changing fuel filter, does fuel pump run constantly. if you cant hear it you can feel it, up behind the ignition. Berrymans B12 fuel additive works wonders. double dose add to gas run bike til hot then let stand overnight, pray a lot and try it again.
here is a free pdf service manual too http://www.carlsalter.com/aaman/Yamaha_VSTAR_650_MAIN_MAN.pdf

Check for vacume leaks first. Rubber lines..gaskets to carbs ect. Also remove and blow out your fuel line to tank and change out filter. Hope this helps.:)

SOURCE: When I fill up my fuel tank, the fuel gauge goes

i think that the problem you face is due to your fuel gauge more than the battery .
the fuel gauge at full tank can be running out of sensor due to faulty gauge mechanism . i would not worry too much as this is common even in cars .
My advise to you is not to over fill your tank and this will resolve your problem .

SOURCE: Idel adjustment on fuel injected road king.\not on

Thats not totally correct. remove your air filter cover. look to the lower right side. You will see a small hole thats where the screw driver goes in to adjust your idle. Ya the dealer has a scanlizer that can also do it if u want to spend the bucks.

Will not idle without choke on 1998 harley daividson road king


you need to get your fuel system cleaned, if its injected try running some high octane gas,and some fuel system cleaner, if its carb'd pop your airbox side intake tube off, and spray some carb cleaner in it while running, if i remember right, your injected though, if that injector cleaner dont work, take it in and pay the piper hahaha

2002 road king classic keeps stalling when i come to a stop and there is some backfire as well . when i first start up the bike it will idle .


If your bike is fuel injected, there is nothing you can do. You must take it to a shop and let them set the idle speed. If it's equipped with a carb, remove the air cleaner cover and look at the square top on the carb. Just to the right of that cover is a screw, the throttle stop screw. Turn this screw clockwise to increase the idle speed. It should idle at about 1000 RPM.

Good Luck

2003 HD Road King - starts fine, idle normal. Once it is warm, idles at 2000 rpm. Does not come back down, even after riding for an hour or two. Only idles normal when cold. Help??


If you bike is equipped with a carburetor, the idle stop screw is located at the top of the carb on the right side. Counterclockwise turn slows the idle speed.

If you bike is fuel injected, a dealer or shop will have to set the idle speed electronically.

I have a 99 road king 1550 fuel injected. on the way on a trip the engine lost power and shut down . cranked but no start. Took it to harley dealer where they found that the computer was fried, front...


Interesting story but other than the low idle, you never said how the bike was running. I must assume that it's running alright other than your concern that it may be running lean due to your fuel mileage. You're mileage is about nornal for an engine as large as yours. My 1340 Evo gets about 45 miles per gallon. If you had a vacuum leak on the manifold seals, you would notice it mostly at idle speeds. The idle speed would probably vary considerably while sitting still. It may even cause one cylinder to miss. As long as your bike seems to be running good, ride it and enjoy it.

My harley davidson road king keeps cutting out like its running out of gas or vapor locking any ideas?


I had the same problem on my 06' (Fuel injected). It was the copper filament inside one of the wire going to the injectors. It took 3 visits to the dealer and 4 hours of investigation to find it.

1998 roadking idles to fast after it warms up.


Is it fuel injected or carbureted? If the bike is fuel injected it will idle fast until the engine warms up...if it continues to idle fast after about 10-15 seconds it could have a faulty sensor.

If carbureted, after you push the choke in does it still idle fast? If so, there is an idle adjust screw on the top of the carburetor just behind the air cleaner.

Do you have a tach on the bike? If you do, then the normal warmed-up idle should be 1000rpm.

High idle below 72 degress


If this is still a problem. I had a similar issues with my 06 Road King. Mine ran extremly hot and the idle was horrible too. On cold mornings five miles in I had to get off the bike because it felt like I was going to burn up. Two years dealing with Harley dealerships, who were completely worthless, and nothing. I even got to the point I told them to come pick the bike up I was not making anymore payments. Well that did not work.

I called a chopper shop, PeteG's in Longwood FL, told them what was happening. I had the carb drilled out, a new breather put on, and pipes (of course those were what the hell). Anyway, since the work was done, I don't run hot, my idle is normal, and fuel consumption has improved by almost six miles per gal. I just hit 43 mp/g this week. Since the repairs were comlpeted about three weeks ago I've put almost 1500 miles on the bike no problems yet.

One note... Do not deal with Harley if your bike is out of warranty. Ask around and find the names of some independant shops. Ask them. The benefit is they usually will give you a straight answer and two they cost a lot less.

Hope this helps.
