Hi, Anonymous and the usual suspects are:
1. Throttle cables improperly adjusted, pinched or need lubrication.
2. Idle adjusting screw needs to be backed off.
4. Air fuel mixture adjusted too lean start with 2 full turns.
5. Intake system air leak.
6. Fast idle choke ramp is not releasing.
7. Faulty automatic choke.
8. Broken throttle return spring.
9. Damaged diaphragm or slide.
10. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector.
11. Multiple carburetors not in sync.

1998 roadking idles to fast after it warms up.


Is it fuel injected or carbureted? If the bike is fuel injected it will idle fast until the engine warms up...if it continues to idle fast after about 10-15 seconds it could have a faulty sensor.

If carbureted, after you push the choke in does it still idle fast? If so, there is an idle adjust screw on the top of the carburetor just behind the air cleaner.

Do you have a tach on the bike? If you do, then the normal warmed-up idle should be 1000rpm.

either a vacuum leak or an idle air control valve problem most likely.the iac is on the side of the throttle body.cylinder shaped with a small harness.

Fast idle after warm up .already changed IAC valve


fast idle is many times caused by a engine intake vacuum leak, use a can of carb spray and spray the top of the engine for leaks, if u hit one u will hear the eng change idle speed, also look for split or leaking vacuum hoses.

hi how are you. your auto choke is bad will need to replace.depending on wich one you have it may only be the vacume choke diafram ( high idle cut off). or it is the electric choke

Excessive idle speed


The problem may also be the automatic choke. It could be stuck in fast idle. check all choke settings and linkages clean if nessesary. There is a separate fast idle adjustment screw on the choke linkage that controls engine speed while the engine is warming up. The tip of the screw rests against a cam that slowly rotates as the choke opens during engine warm up. Turn this screw counterclockwise to decrease the fast idle speed.

I have a similar problem which seems to stop ,if after 20 mins of driving or warmed up engine if you stop for 10 mins the revs die to a more normal 1500 revs! it is a spanish car now living in theUK I think the problem is choke related.
