Idle increase when bike warms up

The bikes start great and idles at about 1000 and then as it warms it will increase to about 2000-2200rpm
Idle will not decrease intil the bike cools down and then it starts all over
Thanks

Honda shadow vt1100c 1986 idile to low after running awhile


There's an idle adjustment screw. The bike runs faster when cold because the fuel\air adjustment is richer on a cold engine. When the bike warms up, the fuel becomes more lean in mixture because the heat causes the fuel to expand, i.e., less molecules of fuel to the firing sequence of the piston. When the bike is warmed up, after say ten minutes, the heat causes a leaner mixture, so adjust the idle on a hot engine (about 1000 rpm more or less). The bike will idle faster when cold, then drop rpm's as the engine warms up. Good luck

Tickover to fast when warmed up.


I don't know the term tickover. If you mean it idles to high then lower the idle. It's a carbed bike right? Idle screw is on backside near front of carb but remember these Twin cams run on oil volume not oil pressure. The bike needs to idle between 1000 - 1200 rpm to maintain proper oil circulation. If you turn the idle down to get that lope or potatoe sound from the bike you can starve the engine of oil and burn it up. These aren't throw away rice rockets of yesteryear.

Try lubing your cables and throttle mechanism first. Do your adjustment when the bike is warm. It sounds like you're making one of the cables too tight.

Hi, I own a Pulsar 150 DTSi (2007). I want to know the correct/most effective technique for setting the idling speed and carburetor volume control screw setting. I have already read many articles on the...


First and formost make sure air filter is clean.Then start bike and warm up engine.with engine warm adjust idle screw(the big screw with spring around it)Turn clockwise to increase and counterclock wise to decrease.with bike idling properly the low speed air adjustment screw (small screw located just above fuel bowl on side of carb)Adjust in small increments 1/16 turns at a time till bike has smooth throttle responce.This screw contols air flow during idle and up to 1/4 throttle.From 1/4 throttle and up the needle setting on plunger inside of carb takes care of 1/4 and up.You usally dont have to mess with needle unless you do upgrades to get more power out of bike.But over time the low speed settings can change due to wear on idle needle and air needle.So thats why you have to make adjustments.If bike still dosent respond or idle correctly I would purchase carb rebuild kit and your problem will be solved.

First of all is this fuel injected or carberated? second my bike will start and idle with the choke open half way. as soon as i ride and go to stop the bike stalls. what is causing this?


your bike is carburated & sounds like it is in need of a carb service, the pilot circuits are plugged & need to be cleaned to rectify your problem.

first get the bike running, turn the idle adjustment up enough to keep it running. start with the air/fuel screw, 1 1/4 turn out. adjust the screw which ever way increases the idle 1/4 turn at a time, wait 10 seconds after every 1/4 turn to allow the engine speed to adjust. As the idle goes up you can use the idle screw to keep it in its normal range. at some point, the idle will start to come back down, this is when you want to start going the other way. idealy you want it set in the middle of the range of when it stopped increasing and when it started to decrease. If you are not able to reach this happy medium within the normal adjustment range, you will need to put the proper pilot jet in and start the process again. This should get you up and running, if it is a generic carb you may will have to adjust the jetting to get the bike performing its best after that, but thats another chapter.

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.

after the bike has warmed up, then reset the idle to approx 1000rpm. then see what happens when its cold. some bikes are cold blooded and the use of choke is necessary for a bit, at least until it warms up...
