SOURCE: 99 HD softail stalling problem
If this is occuring everytime you ride the bike and always when it gets warm. I would think there is a good chance that the sensor in the timing cover is getting hot and then developing a short. You can replicate this synario by taking a hair dryer and warming the cam cover around the timing plate, if the bike wont start after warming the timing cover then you have a bad ignition sensor plate. if the bike still starts you can also try the same technique with the ignition module itsself which should on that model be located behind the battery. heat causes shorts in those 2 items quite often. try it out and let me know what happened.

Your Twin Cam plug should be a 6R 12 Harley Plug. Often times the back fire is just the nature of the beast depending on what type of pipes you are running. Harleys do run lean, its an EPA thing thtas why they choke them down from the factory. Since you have a carb you could have an intake leak around the Intake. Also Under the carb is an adjustment screw. Harley plugs it up so people don't play with it. You have to just drill out the plug this will set your air fuel. Whenever I take a carb off I drill out that plug. Heat your bike up operating temp and ear tune that screw. Only other way is with air fuel analizer or a dyno. good luck.also that backfire is caused by fuel hitting your exhaust when you let off just to let you know.

SOURCE: valve noise 2006 road king
Hello redevil67...This is normal for the HD engine, it going to have valve train, top end noise at some point, some as early as 2000 miles. If you take it to the dealer they will try to sell you on worn tappets...key word here SELL..I've seen this many times, dealer replaces componets, 2000 miles later the noise returns.
These are hydraulic valves and as you probably know they operate at zero lash. Personaly, i feel that the problem is that the cams are not hardened properly or machined incorrectly.. When the leading edge of the cam lobes wear to a strange profile it tends to snap the lifter up in the lifter bore. This causes the rest of the valve train to rattle. You hear the noise on top but the culprit makin it, is the cams..Many chose to go with an aftermarket cam, such as an andrews...Another suggestion, is to switch oils. Don't know what you are useing now, but i'm not a fan of dino oil. As the temperature builds the more an oil is stressed. Lucas full synthetic 20w-50 or Mobil1 15w-50 are both excellent for anti-wear and long term protection.
I hope this helps, please rate me a fixya and good luck with your bike.

The same thing just happen to me and a friend of mine on our 2001 Road Kings. I am 95% sure your problem is the crank position sensor. We replace ours and the bikes are back to their glory.

Lift the back of the tank up and prop it up. Remove the chrome beauty covers, find spark plug wires and remove. Blow out with air first. Chaz Moto DC
