If it's liquid cooled, then that grey smoke is more than likely steam ( the head gasket is on it's way out). If it was burning oil, you would able to smell it.

White smoke from exhaust after changing fuilds


Is it condensation or actual smoke? White smoke is associated with diesel mixed in petrol and with quite strong smells. I suspect that it is condensation as water vapor is a by product of combustion and the motor/exhaust will have to warm up to clear it. Check for water droplets at the end of the exhaust to confirm condensation. Burning oil will cause a blueish smoke to emit from exhausts.

Some gray smoke when starting, worse with choke on


That sounds normal. Dark smoke is excess fuel due to the choke. Could be that the carbs need cleaned.

White smoke coming out of my yamaha 2008 r6 whenever i start the bike. why is the white smoke coming out ?


Hi, Anonymous your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. WHITE SMOKE on start-up can is usually caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers.
2. BLUE SMOKE on start-up is usually caused by failed valve seals. Smoke that is constant while riding is usually caused by valve to guide and piston ring clearances that have exceeded service wear limits.
3. BLACK SMOKE on start-up is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke/enrichner or not in the off position, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

Might be your miracle in a can fix burning causing the smoke. If its coming out of a joint where it clamps, try to tighten the clamp. Sometimes there is also an exhaust gasket where the one pipe slips into the other pipe that could be broke or missing.

Klx 110 started smoking grey smoke burning oil there is also oil on the end of the exhaust pipe. bike still runs good.


If the level of engine oil keeps going down (even in very small amount), then it shows a problem with piston rings. Hope it helps and let me know if you need more advice. Please don't forget to rate the answer it helps me, thanks!

Oil is leaking out of my air filter and grey smoke is comming from exhaust


the grey smoke is more than likely the air filter being blocked by the oil, it also sounds like unburnt fuel, check your choke ect to see if its seating properly, give the air filter a clean, then see if any more grey smoke appears (it'll start again when oil clogs it again). also check the exhaust system for a blockage e.g. worn/old gasket ect. change the oil check the colour make sure no gaskets have gone. also put the exact amount in as stated in owners manual (too much oil=too much pressure and can seep through oil ring on piston and leak into air box and make your bike run rubbish. hope this helps, it might not but worth a try.

White smoke coming from exhaust


White smoke could indicate coolant in the combustion chamber. Not likely if you have an air-cooled bike. It could also mean that you are running in a cold climate, if the temp is around 20 or less I would call this normal.

If your bike is water cooled I would keep a close eye on your coolant level and oil level. A blown head gasket could allow water to get into the combustion chamber (causing the smoke) or mix with the oil (even worse). If you notice it using coolant I would have it checked out by a mechanic. If you want to check it yourself, do a compression check on both cylinders. If one is rather low, there is your problem.
