Possible cause for heavy loud knocking in engine area. Bike runs only at high idle.

This sounds like there might be trouble with the bearings on the crank . Best to have it checked, or tear it down to inspect.

Trottle cuts out on 09 ultra classic hd

Have you pulled any error codes?
If so, what are they?
I have a troubleshooting flow chart for a 08 Road King, it might be close enough for ya.

From your description, it's going into "limp" mode, so it can limp home.

Pull any error codes and repost them.

Trottle cuts out on 09 ultra classic hd

There's probably a sensor in your throttle housing that regulates the amount of fuel that goes through the throttle body to the engine. The sensor could be located on the throttle or you may have a bad throttle body. There are computers on both ends. I believe you ought to call the dealer and find out

Engine light goes out after starting and idling. When riding speedometer is eradic and engine light comes on. Bike running fine

I would remove the speed sensor on the transmission and clean it..Just wipe it of. It's probably loaded with metal shavings. If cleaning doesn't work then you'll probably have to replace it. I own a 2000 FLHTC and I have to remove and clean mine at least 2 times a year. As for the engine light being on. The engine light should shut off within 5 to 8 seconds of the bike being started. You need to run the diagnostics through your speedometer. If you don't know how then you need to buy a service manual for the bike so you can do the diags and look up the codes.

2005 HD Ultra vibration at idle

Hi Vernon, and the usual suspects are:
1. Wheels and or tires unbalanced, worn or damaged.
2. Engine/transmission/vehicle not aligned properly.
3. Primary chain badly worn or links tight as a result of insufficient lubrication or misalignment.
4. Engine to transmission mounting bolts loose.
5. Upper engine mounting bracket loose.
6. Ignition timing incorrect/poorly tuned engine
7. Internal engine problem/ flywheel shift runout should be .003" max.
8. Broken frame
Good luck

Check engine light on

Not much you can do at home since the bike is a FI model. Get a HD tech to pull the trouble codes with a scanner. At least you will have a starting point to diagnose the problem.
