2005 xl 883 Custom. Will not idle it is running to rich. Have to stay in the throtle to keep it running at idle. When I turn of the fuel and rev once it idles perfect.

Duplicate question already answered

How do you know it is running rich first off???

What DTCs are set next???

is the fuel filter stuck in the tank not allowing it to stay in the fuel when you turn it on it's side?

yes it will unscrew after it pops up give it a twist to the left and it will come out then.

1.Inspect the accelerator pump diaphragm
for holes, cracks or deformation. Replace as necessary.
2. Replace the pump rod if it is bent; replace the boot
if it is cracked. Also look into the ventura when twisting the throttle and see if you see a stream of gas from the pump with the engine NOT running,if not then the pump isn't working...

hi,it sounds to me like the bike is actually running to lean,or,you have a leaking exhaust,what happens is when you let off the throttle,clean air is drawn into the exhaust through any leaks,the next time the bike fires,the hot exhaust gasses mix with the air in the exhaust and you get a backfire when they all ignite,check your exhaust system for leaks first,if you can feel air coming out of seams etc when the bike is running then air can get in to,changing theair/fuel ratio is quite easy,simply with a screw driver turn the screw in(richens mix)untill the bike starts to struggle,then back it out untill the bike settles into a nice steady idle,if you take itout to far(leans out the mix) the bike will again start to struggle,all you have to do is find the mid point between the two and you will have the mixture pretty close to bang on.if you are not confident to do this ,take the bike to a shop and have it done,it will be a relatively short visit and wont cost much...hope this helps..cheers

It's time to service the carb. You've got raw fuel getting into the carb when it's not supposed to be. You've got either something causing the fuel level in the float bowl to be too high or you've got a bad accellerator pump diaphragm. The latter is the most likely. When the diaphragm gets a hole in it, it allows fuel to slowly dribble into the throat of the carb through the little brass 'squirter' causing your problem. Check your accellerator diaphragm.

No its not a fuel filter problem,Your car would not rev if it was not getting fuel.Its your idle controll valve.Remove the air intake pipe and spray with carb cleaner and see if that does the trick first Could be just a dirty throtle housing.Good luck.

Is your 883 fouling plugs AS if warms up or AFTER it warms up? The enricher circuit is designed to be extremely rich in order to start a cold engine. If you allow you engine to "warm up" with the enricher on the entire time during warm up, plug fouling is typical. You should use the enricher to start the engine but disengage it as soon as you can keep the engine running with the throttle. Use the enricher just as little as possible.

If your plugs are fouling AFTER warmup and while riding, your carburator is jetted too rich or your air filter is in need of servicing.

It sounds like the idle jet is clogged, if the choke is on it will continue to run however (very rich).black unspent fuel which will blacken the spark plugs and eventually foul out...take the carburator off and take it apart....there is an idle jet, blow thru it,or run a very fine wire thru it, you should be able to hold it up to the light and see the light.....same thing for the main jet...make sure the float bowl is cleaned out and install a new fuel filter.....check the gas tank for any rust..........if there is rust in the tank.....it must be cleaned and a tank sealer must be applied......there are several kits available..
