Have you changed the fuel pump fuel filter? and have you checked the cold start gas valve to be sure it is working? it gives extra fuel on startup.

Blown radio memory on my 2003 H-D ultra classic

Hi Dorin, you have a hard/dead short that should be easy to find generally they are the easiest. Time to get out your test light and start tracking the wire from the power side of the switch, circuit breaker or the blown fuse receiver, when the test light quits lighting you are very close to your short.

Starting problems 2003 ultra classic

If the starter winds and there is a clicking sound, but did not crank the engine, it means the solenoid did not engage the starter bendix gear drive to the crankshaft.
You have to pull down the starter assembly and check the parts inside. By putting a direct power to the starter you will see what's wrong w/ it.
If you have no knowledge on such repair, a technician should do the job!

Tell me if that solved your problem so that I could guide you for repairs.

Hope that helps!

I,ve got a 2008 Ultra classic, and want to change the fluids. It's got 8000 miles, and i dont have a owners manual. the oil, i can figure out , but the trans, and the primary I dont have an idea.

On the bottom of your transmission, there are two drain plugs, one for the transmission and one for the engine oil. The plug in the center is the transmission drain plug and the one toward the left front is the engine oil drain. The primary drain is a small pipe plug that takes a Torx wrench located at the bottom of the primary cover towards the rear of the bike.

Engine oil three quarts with filter. Then start the bike and let it run for a few minutes. Shut down the engine and check the oil level with the dipstick. The dipstick has two marks on it. "Full Cold" and "Full Hot". Fill to the full cold mark.

Transmission takes 20-24 ounces of oil and the primary takes 38-44 ounces of oil. Do not overfill the primary as it will cause your clutch to drag. All three sections take H-D Syn3 20W50 synthetic engine oil.

I want to change my motor oil which is the drain plug, i smell exhaust fumes untill the motor warms up?2000 ultra clasic

The oil tank is on the bottom of the transmission. There are two drain plugs. The drain located about the center of the oil pan is the transmission drain plug. The drain plug nearest the front left of the oil pan is the engine oil drain.

A rich smell to the exhaust fumes when the engine is cold is typical. The computer on your bike (and your car) senses that the engine is cold and requires a slightly rich mixture to run. When the engine warms up, the computer leans the mixture back out. This is why you don't have a "choke" on your bike, the computer changes the injector dwell time to richen the mixture instead of you having to use a choke.
