Sounds like an oil pump issue. Can you hook up a pressure gauge to find out how much you have at idle vs with throttle? Probably not a real problem but you might want to replace it anyway. Obvious question here, check oil level?

SOURCE: oil plug

Bottom of oil pan...underneath the bike. Approach the undercarriage from the leftside of the bike, so you will not have to deal with the exhaust pipes. Remember to change your oil filter with every other oil change.

SOURCE: oil light

It would be best to have an oil pressure check. Get a reading at both idle and at 1500rpms.
Could be oil pump or bearings.

SOURCE: feels like a misfire

It's time to adjust the valves. You have tight valves and most likely need to adjust the cam chain. This is classic when the valves are tight. Most likely you can start it up when cold ok but after a few minutes performance deteriorates this being due the valve lash being to tight.
The miss fire is due to a lean situation.

SOURCE: Backfire out of carb!

Remove and clean the carbs. Clean the air filter and install new stock plugs. Re-mount the carbs and then balance and sync them. Now would also be a good time for a compression check. Valves and rings do give problems sometimes but these problems show up first as a lack of power. Since you didn't report a power problem I doubt if valves are the problem.

SOURCE: My XV125 will only run on tick-over until warm....

ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Please rate this solution. Thanks!

Engine idles up to 2500 and after 5 or 7 seconds, goes back down to 1200 rpm 2002 escort SOHC


Clean out the throttle body carefully and replace the auxilliary air idle valve. There is a resetting process for this valve so dont just fit and hope!
Check on Google or forums but i think ...when fitted you turn on ignition but dont start car , then put the accelerator pedal slowly to fully open, hold it for a min then release. start and drive car until warm and the recheck.
If the idle is high then settles it is not an air leak. It is something stuck that then releases which is only throttle flap or idle valve. It is always a goid idea to replace fuel, oil, air filters on normal service intervals.

I have a 96 1200 bandit.when cold it revs up and down as it shud do but once warm when u let off the throttle and change gear the revs take few seconds to go down the engine still revs on etc. carbs av...


When a engine is cold the revs should be higher ( choke on ) but nit going up and down. If you release the accelerator and the engine still rev's up maybe the accelerator cables are not properly installed on the carbs. Also a air leak is possible. Check the cables and air leaks at manifold including the holes from manifold where vacuum gauges should insert when carb calibration is necessary. Those holes should have some caps on.

05 Bandit 1200S idles low, run rough at low rpms,


Try buying new diaframs for your carbs, because of the diafram and piston operation, if the diafram becomes weak due to heat from your engine, and by the diafram not beeing rigid enough, it hesitates to lift the needle out of the jet causing the lack of fuel at low tack/rpm when throttling up or accelerating slowly.

I have 1200 bandit with fuel getting into oil


Check the Compression in all 4 cylinders, if the compression is low on one cylinder, squirt some oil or or WD40 down the bore and immediately recheck the compression. If the pressure goes up a fair bit you have a broken ring, if not you could have a burnt valve. If your getting fuel in the oil it definately sounds like a ring problem

Engine surge during warm up.


Try changing your PCV valve make sure the hose is clean and not full of oil. Also check the elbow end that goes to the intake they tend to collapse from oil saturation. Hope this helps.
