Check HT leads, connection and the spark at the plug to see if it nice and bright.

Is the battery charged fully or is it old? They don't last very long on Harleys.

See if the regulator is any good ( dealer or friend swap if possible to check).

Ive got a 06 harley 1200 sportster when it warms up it starts to cough an sputter through the carb dosent do it all the time but on ocassion it runs fine just takes spells that it does it rebuilt the


Hi David, popping, coughing, spitting, or backfiring through the carburator or induction module can be caused by air getting sucked in combustion chamber do bad intake seals leaking. Leaking exhaust gaskets can also be suspect. Remove air cleaner and backing plate, while engine is idling spray WD-40 or Brake Kleen around intake manifold to head area, if RPM's increase you have an intake leak and seals need to be replaced, also spark plugs will be burning whiter than normal. Good luck

Bike runs great. until it warms up then it backfires and spits and sputters


It sounds like a fuel problem. Next time it starts doing this, take the air filter cover and the air filter off. Leave the air filter backing plate on the engine and go for a ride. If it runs better, the carb is too rich. If it runs worse, the carb is too lean. They are usually jetted very lean from the factory to meet EPA standards.

If the bike is fuel injected, the dealer will have to change that as it's not owner servicable.

If you run it too long with the enricher on when it's cold, it will foul the spark plugs. The enricher is way rich. I usually only run the enricher long enough to get the warm enough to run while holding the throttle open or using the throttle lock. Don't run the enricher any longer than necessary. Put in a new set of plugs that try that. Big Twins are bad about the enricher fouling the plugs, Sportsters are the king of fouled plugs when using the enricher. When you purchase spark plugs, just buy the Autolite 4164 plugs. They run as well as anything out there and don't cost nearly as much.

Good Luck
Steve

How do i drain the fork oil on my 2005 dyna fxd


There should be a drain plug on the trailing side of the slider. Some have cross point screwdriver heads on the plug others have allen or hex head plugs. Remove the plug and work the forks up and down. If all fails, you can remove the entire tube and turn it upside down.

How to change oil in 2003 HD FXD Dyna Super Glide


remove the drain plug from the oil pan, you will need either a 3/4" box wrench or a 5/8" box wrench and the drain plug will be facing forward on the the oil pan. It is easiest to remove this drain plug from under the right side of the bike. put drain plug back in after about 10 m,inutes of drain time and tighten to 18 ft. lbs. Dont forget to change the oil filter as well.
