Changed oil clogged air filter with new after market air filter bike ran good until the third time I started it it would not idle unless it was choked


My Harley is very slow to warm up, it also does not like to idle without choke unless it is good and warm. It could be the clogged filter was acting like a choke, but ruining your gas mileage. Now with air flowing smoothly the engine needs a bit of choke to idle. It should not need choke once it is fully warmed up unless your idle speed is set too low. With the engine hot, check RPM if you have a tach. If too low, adjust the idle speed at the carburetor. I suggest you find the adjustment while the engine is cold.

Recently purchased a sportster 1200 xl low rider 06 plate. Which is great in every way apart from town use, I find that once the engine has got warm I am having to continually blip the throttle to stop it...


Regrettably, it is a "norm" for an H-D Sportster but it's fixable. The engine is jetted very lean in order to meet EPA emission standards. The lean mixture is what causes the spitting back through the carburetor and poor idle qualities of the engine. You can improve the low speed and idling characteristics of your engine by going up one size on the low speed jet and readjusting the idle mixture. If you can do this work yourself, let me know and I'll give you the instructions on how to do it. If not, take your bike to a performance oriented shop and talk to them about it. If they have a dynometer and an exhaust gas analyzer, they can fine tune your bike to where it runs like it should.

Good Luck & Ride Safe

I have a 2005 harley davidson sportster xl 1200 custom. after bike is at normal operating temp.when i stop for redlight or stop sign, bike idles to fast.i can let out on clutch little bit and it will slow...


If the carb is adjusted correctly, the engine will not idle without the choke when cold. I will usually take at least 3 to 5 miles of riding to get the engine warm enough to idle by itself without the choke. If your bike is a full operating temperature, it should idle at about 1000 RPM. If it's idling higher than this, you need to slow it down a bit.

Remove the air filter cover and look at the top right side of the carb. You'll see a screw there . This is the throttle stop screw. Turn the screw counterclockwise to lower the idle speed to 1000 RPM or so. Blip the throttle and let it settle back to idle. Reset it if necessary. Once set, put the air cleaner cover hand on.
