2003 HD Fatboy has a miss. New plugs, wires and air filter. RPM's are high while idling after warmup, and engine tends to sputter when pulling out. It only sputters at the low end of the throttle. Any ideas?
I take it its carb. after it warms up to operating temps does it stop the sputtering? thats just a HD CV carb doing what it does til hot. Im not talking a 2 min warm up and off u go im talking operating temps of 200 plus. Is the carb an S&S? Your going to have high rpms til the temp kicks it down if its injected
Itake leak spray carb cleaner on connection carb to inake and intake to heads if idle changes replace gaskets if your feul injected rplace your temp sensor
