2000 Harley Davidson FLHRCI Road King Classic Questions & Answers
My 2000 Road King bucks and hesitates when at low speed, now recently will stall out, what can I do?
You don't say if any work has been recently done to this engine, or if it has had regular maintenance such as tune-up or carb/fuel injector cleaning. My first thought is an extremely lean condition. Does it back-fire through the air cleaner?
Causes of lean condition could be dirty fuel filter, mal-adjusted carburetor idle circuit, dirty low-speed jets or fuel injectors, or even the ignition timing has slipped. If the filter hasn't been changed recently, do that first. Then, a simple solution for clogged fuel meters that oftentimes works is to add fuel-injector cleaner to your gas tank. An entire bottle to one tank (normally intended for a 17-gallon auto fuel tank) would be about right. Expect to do this for several tanks, then a couple times/year to keep the cab/injectors clean. If that doesn't work, time to get the tools out. Start with a Harley shop manual for your model. (If the cleaner makes things worse, your fuel tank is also filthy, and it's time to clean that as well as the carb/fuel injectors.)
