You may need to replace your spark plugs

as the idle should remain constant as long as the tune of the bike is good IE oil changes done regularly / plugs cleaned and or gapped , air filter cleaned or replaced all of these can affect your bike.

hope this helps

Idles with 1/2 choke. If open choke, or throttle - engine dies without any RPM spike. Carb was cleaned, jet is clean. When idles, there is gas in the primer bulb.


Hi, Andrew and the usual suspects are:

1. Fuel cap or fuel tank is not venting properly.

2. Fuel filter clogged.

3. Fuel line pinched or kinked.

4. Float needle and seat sticking.

6. Carburetor bowl vent line clogged/blocked/pinched.

7. Idle adjusting screw set too low.

8. Air/fuel mixture screw set too lean.

When is a valve adjustment due on a 06 R1

Instructions
    • 1 Open the choke by pulling the choke lever on the left handlebar control toward you. Set the bike on its kickstand, put it in "Neutral" and start it up. Allow the Road Star to warm up for about 10 minutes before continuing with the adjustment procedure.
    • 2 Locate the idle adjustment screw on left side of the bike just below the rider's seat. Twist the adjuster screw clockwise one full turn. This will ensure the bike stays alive so you can adjust it to the proper setting.
    • 3 Close the choke lever and listen to the engine carefully. Twist the idle adjustment screw slowly counterclockwise. You should hear the engine speed start to slow.
    • 4 Twist the idle screw counterclockwise until you hear the engine start to sputter and die. When this happens, stop and turn the screw one half turn clockwise. Your bike should now be idling at the correct speed.

This is a classic example of a clogged pilot jet in the carburetor. You need to clean the carburetor circuits and jets.

Kawasaki Ninja 250 running problem


This could be due to timing screw being incorrectly set
Locate gold timing screw on the carbrettta turn it clockwise only slightly till bike idles without choke on, Then when choke it on it should idle a touch higher.

Bike wont kick start or idle , it will coast


first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

Ltz 250 wont idle needs full choke to run.cleaned carb all jets new diaphrams. cleaned air filter and all hoses. backfires and hesitates half and full throttle.


hi,sounds to me like the air fuel ratio is all up the ***,locate the air/fuel screw on the carb(normally on the side)screw the screw right in untill it stops,then back the screw out 1.5 turns,this should get the bike to run without the choke,once you have the bike running simply turn the screw in or out untill the bike settles into a nice steady idle,should be good to go,hope this helps...cheers

Bike will not stay running with choke off.only has 600 miles on it.


It is likely that the dealer set the idle properly but as the bike is new it may need to be reset, most first services are scheduled for 600 miles or 1000km so that the dealer can make necessary adjustments.
You can check the location of the idle screw in your owners manual. Once the bike is nice and warm, try screwing the idle adjuster screw in 1/8th of a turn at a time until a steady idle is acheived. Otherwise take it back to the dealer, thats why you have a warranty.

I let my bike sit for asbout 3 years and now it wont stay on


The pilot jets are still gummed up. This jet controls the idle port and usually gets overlooked. To clean it the jet must be removed along and the adjusting screw as well. The circuit must be cleared of gum. For each individual carb, when removing the jet and the adjuster, count the turns then remount that number of turns. Now turn the adjuster screw 1/4 turn counter clockwise.

I have a keeway 125 bike new idle prob


Pull the carb off the bike and clean it inside and out. Be sure main jet is clear. Remove the two screws on the outside throat of the carb and spray into the screw holes as well. Be sure to put these two screws back in the same hole they came out of. IMPORTANT > > > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward.

Put the rest of the carb back together and install the carb. Turn the gas on to let the float bowl fill then start the engine. Chances are this will fix the problem. I suggest that you install an in-line fuel filter to prevent this happening again.

Last item> You should have just a little bit of slack in the throttle cable where it goes into the top of the carb. Not more than 1/16". Let me know how things turn out.

Please rate this solution as " FixYa " if all goes well. Thanks
