1200 sportster idle's fine with choke pulled out, but dies as soon a you turn the throttal. Will not Idle unless the choke is pulled all the way out, it will die if you try and turn the throttal or push in the choke. 1996 ,1200, H.D.

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.

is it warmed up enough, Hondas are cold blooded. is the idle circuit clean and allowing the proper amount of fuel to flow as this sounds like the problem with it dying when the choke is pushed off.

A 2003 model with only 50 miles?? Wow....well,since youve already taken the carb apart and cleaned it,did you hook up the vaccum line for the VOES switch on the intake manifold? If so,..when you get the bike running,..spray some brake clean around the intake where it bolts to the heads.If the idle picks up,or starts to sputter,..youve got leaking intake gaskets. Which is a good possibility on a bike that old with that few miles on it.The choke essentailly adds more fuel to the motor,and by what your saying,the bike is obviously running lean. Also,...im ASSUMING that you have fresh gas in it,and the petcock is turned on.

carb is dirty--old gas has corroded passages-try runnin it at idle for a while without overheatin it-may want to put somes fans directed at cylinder--if doesnt help then a solvent-not dollar carb cleaner shud be used--get a clymer book for procedure

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.

Unless the carburetor has been modified, the only adjustment is the idle speed. The Idle Stop screw is located at the upper right side of the carb. You may have to remove the air cleaner cover to access the screw. Clockwise rotation increases the idle speed. Adjust the idle speed with the engine at full operating temperature.

Carb or EFI? Need to know before an answer can be given.

lol buddy if its not idling turn the idle screw in until it idles get back to me if no difference

800 rpm is to low for a sportster , it will cause oiling problems. (lack of). 975rpm @ 1175 are the ideal settings.also look for manifold air leak. spray wd 40 around all inlet manifold connection areas, if engine hesitates you may have a leak.

your choke could be sticking or other carb adjust needed. also get that clutch inspected before u start pedaling!
