SOURCE: my bike stutters at full throttle

Have you checked the fuel filter ? Some are in line others are in the tank petcock. I am Not familiar with that model but it sounds like it's a fuel issue.

SOURCE: whaen car idles its fine

Sounds like your turbo is done. If oil is coming out and it won't build boost, it's your turbo. I wouldn't push my luck. If you continue to try to drive the car and the turbo finally goes to pieces. Those pieces will most likely go down inside your motor and that would be an expensive mess to clean up. Sorry. Don't forget to give a vote. thanks.

Probably needs a tune up. Clean air filter, fuel filter. Clean the Mass Air Flow Sensor & Throttle body. May need to clean the fuel injectors.

Idles fine sputters with slight throttle increase stalls out intermittently. Runs good at full throttle


sounds like a air leak in the throttle body check all seals and pipes tighten back down or you could change the gasket or put some sealant in over the old gasket.

Nioce bike sounds like a bad injector though.
You could try to remove them one at a time.injector cleaners might ev en help first but find a really good one.
You gotta use the highest octane on that bike also.

I have a Kawasaki Ninja, ZX6r, 1997 F3. The bike starts great and rev's great when standing. At high rev's its as sweet as a nut. The problem seems to be when riding the bike and the revs are below 4,000....


There are adjustments on carbs for low speed air intake (air mixture screw)find out factory settings and reset that mixture.Sounds to me like those adjustments are out of sink.If so the bike will run very bad from idle to about 1/4 throttle then run great from there up to full throttle.this definitly sounds like carb problem.

I would check the ignition system as an electrical fault or timing fault will give this problem. I don't think it is the carburettor, it may be but I don't think so.

Whaen car idles its fine but when driving it sputters an when it builds boost it blows the intake pipe off the throttle body an oil comes out of the throttle body


in your car the air ventilation system is freeze up causing a build up of pressure which caused the oil to burst out. there is the mosture sludge build up under the oil fill cap . its advisable to clean everything up and then check out by starting the car. also spray crab cleaner in the throttle body and check out. as per me the problem is causing because of :-- I guess the breather vent tube was full of oil - frozen in there somehow. Must have to do with that sludge buildup on my oil fill cap. This is the one coming off the front on the left side of the oil filter. It goes down under the engine. This blockage caused a pressure buildup in the crankcase which caused oil to blow by the pistons and into the combustion chamber and out into the air intake hose and throttle body. get the spark plugs removed and cleaned up all the oil. The reason it sputter is because of all the oil in the combustion chamber. No air could get in. get the oil change and insulate the breather pipe in case of future freeze ups. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

07 kawasaki kx250f backfires


Hey i have several solutions for you.
The first is have you checked valvue clearence lately, because if the valvue clearence is either to high or to low then it could cause it to back fire. The next solution is repacking your silencer. The next solution is there is two main gaskets in most dirtbikes, one, which is located where the pipe mets the motor. Also the other gasket it where the mid pipe meets the head pipe. The bike fire is usually being caused by extra air. By the way checkin valvue clearence is extremley easy it may sound hard but I do after every ride.
