Your bike's timing can only be adjusted through an interface to your ECM like the Screamin Eagle Race Tuner. Have you made any changes to the exhaust or intake? Have you added and aftermarket item like a Power Commander? changes in these areas could account for the problem you are having. hope this helps.

What causes a 2002 harley road king with fuel injection to backfire at idle?

Looks like a leak at intake manifold. Start the engine ,spray a Carb cleaner on the manifold close to the Cylinder's and if you hear a change on idle ,then you have an intake leak.....

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

Fuel in tank,got spark but will not fire without starting fluid sprayed to intake

Sounds like you're not getting fuel for some reason. If your bike is equipped with a carburetor, the fuel petcock may not be opening properly. In 1996, Harley went to a vacuum operated fuel petcock. The diaphragms in these valves goes bad and will not allow fuel to flow from the tank to the carb. Pull the fuel line loose from the petcock and try to start the engine. You should see a good flow of fuel from the valve. If not, check to make sure the vacuum line is connected to the backside of the valve. If so and you still have no fuel flow, you have a bad petcock. If the bike is fuel injected, you'll probably have to take it to a shop. I have no experience with fuel injected bikes. It could be a bad fuel pump in the tank or something else. Fuel injection is out of my expertise level. I work on the older bikes that the dealers will no longer work on. I hope this helps a little.

Good Luck

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.

02 road king fuel problems have a half tank of fuel starts misfires and back fires though exhaust and starts hard

If you have a carb equipped bike and the bike has been lowered in the rear, you could be running out of gas on your main fuel switch position. You may have to go to reserve at that point. If the petcock is located at the front of the tank, the fuel is more to the back end of the tanks if the rear end of the bike has been lower. If it's fuel injected, I have no idea.

When i start my 2000 road king and rev it up it blows black smoke.Any ideas

Black smoke is usually and indication of a rich mixture. Now, you didn't tell me whether your bike was carburator equipped or fuel injected. If carburator equipped, is the carb the stock carb or has it been changed. Still, regardless of whether its carburated or fuel injected, the mixture is way rich when revving. If the bike is equipped with an S&S carb, this is typical and it has an adjustable accelerator pump and most people get them adjusted too rich. Find out whether your bike is carb equpped or fuel injected and let me know. We'll go from there if it's carb equipped. If it's fuel injected, you'll have to take it to a dealer.

1997 flhri road king is missing running rich and popping

According to your description, your bike is a FLHRI. The "I" indicates that it is fuel injected. There are no adjustments that the owner can make to the fuel system. You'll have to take it to a shop,

Good Luck

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.

Fiited a k and n filter to my 2000 road king but it would not start first thing in the morning and run **** until i put the old back in again, do i have to put on the fuel pack just to have sports air...

Although I don't do fuel injected bikes, if it were a carbed bike, I would say that you would probably have to rejet the carb when you changed the air filter to a free flowing model. The same applies to a fuel injected model too, I would suspect. But, it may be within the "range" of the onboard computer you have. Take it by a shop and ask if the fuel map can be changed to accommodate the K&N Filter.
