Usually backfiring out the exhaust is caused by air leaks into the exhaust system. When you back off on the throttle, the mixture should be too rich to combust in the exhaust system. If your system is sucking in air and leaning the mixture to a combustable mixture, you get the backfireing. Check the gaskets at the heads, and the connections at every joint in the pipes including the equalizer pipe fitting.

Good luck

2001 roadking EFI very fast idle


Hi Anonymous, high idle on fuel injected models can be casued by a faulty IAC valve located on the top front of the induction module. It has either failed electronically and needs to be replaced or mechanically getting gummed by contaminated engine blow by. You can try cleaning the unit by removing the air cleaner and backing plate, unplug, unscrew and remove the IAC. Using carb cleaner and " LOW " volume compressed air to clean the metal pintle and shaft that is spring loaded and has an operating length of just under 1 inch. Aventurous souls who did not heed the low air warning have launched pintle and spring into parts unknown. There is no guarantee this will work but worth a try since a new one is $50 Good luck picture pintle IAC valve harley Google Search

Check the air filter is clean, and the ignition for correct operation. The plug indications are that the engine is running rich (too much fuel) or that the ignition spark is weak.

Hi Jenannis, 4 out of 5 Harley Gods give this one a thumbs up for magnetti marelli, but just to be on the safe side contact your local dealers parts department for confirmation. Good luck
