White smoke coming out of exhaust

I currently have white smoke coming out of my exhaust. The bike lost compression, it will start but it smokes a lot. There is a rattling sound that I can hear.
I was riding it, it lost compression, shut off and then when I started it back it had hardly any strength. I brought it home and it has been sitting there.
It is a custom Harley bike 2002 with a Harley engine, looks like the Dyna. 1200CC according to the title. This is my first Harley so I apologize if I sound ignorant. If you can guide me I would appreciate it.
I am located in Fort Lauderdale, FL

    I just pulled the plugs they are black, not soaked in oil but the plug itself is black small residue of oil, one of them in the top portion has a little amount of particles but looks like it came from...

    Excuse my language not fluent in this but the top of the plug has the arch then space then the button looking thing the outer part of the button looking thing has like a scratch where it looks like the particles on the tip of the arch came from there. I hope this helps.This plug came from the rear cylinder part. What do you mean the color of the electrodes?

    Had barely any oil, I put oil cranked and now the smoke is a lot more as for power it has the same amount of power just by cranking and reving once it is strong its just the smoke could that be a seal of some sort?

    Well, I took apart the top end of the engine and there was oil in two of the corners and the rods that are standing up I just pulled upwards and they came out I noticed they are like bolts and they were just loose. Is that my problem?

    Thanks, I did resolve the issue back 2010, unfortunately during my divorce December 2010 the bike disappeared and was sold by my X for $400. Either way, just in case I am rebuilding now, and I did manage to get a custom chopper that has an open belt drive, says trickshift, looks like BDL and I wanted to learn how to tighten the primary belt drive. Would you know how to do that? It would be very helpful.

If it's sucking water into the combustion chamber i suspect the plugs will be very clean... check the engine oil ... what colour is that... and yes.. a compression test would be in order

White smoke is usually a sign of burned oil exhausting. A rattling sound would be more indicative of a broken or stuck valve than a cracked head gasket. Have you done a compression test? It's possible that what has happened is an exhaust valve has broken or is stuck in open, causing the gasses which normally create compression from combustion to escape continuously rather than build compression. The white smoke might be from bad rings, or might simply be smoke from the exploding fuel escaping directly to the exhaust. Normally on the compression stroke, the intake valve opens, allows fuel to enter and closes as the spark ignites the fumes. During that time both valves are momentarily supposed to be closed. However, with a broken or stuck exhaust valve that can't happen. Are you getting smoke from all the exhaust pipes or only one?

    As you can see from Bunnydawg's confirmation of what I already told you, odds are it's your rings and/or a valve issue. You'll definitely want to take a closer look at those two items or have a mechanic give it a good thorough once over. As with a car engine, a vacuum test might give you a little insight too, but with bikes vacuum is not as reliable of a source of diagnostics. In the case of a motorcycle a teardown and visual inspection is the best method for making this determination. Hopefully this helps.

  • Randall LaClaire Feb 07, 2009

    Not trying to start trouble here, but it's kind of lame for someone to come in here, pretty much just agree with what someone else said, then get rated the same for it. I could see if you had some original input but that's just silly.

  • Randall LaClaire Feb 07, 2009

    Ignacio, you have a point and my apologies for being short with other experts at this point. I suppose I missed that point you made, and it's a very good and valid point. Much like doctors giving second and third opinions that concur with each other. I do owe an apology for my terse comment to you other guys and gals out there. Unfortunately I've had trouble of my own. I've spent the last week working in near 0 temperatures on our family vehicle in preparation for a move, and the old adage "Fix one thing, another breaks" has been holding true. Again, sorry about that, and keep up the good work, everyone!

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.

I've a Pulsar 150cc bike bought in may 2009, roamed around 70k kms. Problem is it is exhausting white smoke only when it is started, mechanic at a Bajaj showroom says it has come to bore and had to be...

Hi, if the smoke really is white smoke and is only present when you start then it COULD be just water vapour which once exhausted (after warming up) would result in normal exhaust gas colour from then on.

If it is burning white smoke all the time then it could be piston ring failure. As this is a single cylinder engine you would need to find out what the normal compression reading should be and then check your reading with a compression tester. You probably don't have one but most motorcycle garages should be able to test it for you for a reasonably small fee.

From what I can find out online your compression ratio should be 9.4:1 which means your psi reading on the gauge should be around 124 psi - this may be a little lower due to engine wear.

If you can get hold of a compression tester, make sure you have the bike sized fitting on it (same thread size as your spark plug) and then warm up the engine for a few minutes then turn it off and remove the spark plug. Then fit the compression tester into the cylinder head in place of the spark plug.

Turn the engine over using the electric starter if you have one or the kick start if you don't (it wont run without the spark plug but it will turn over) and note the reading on the gauge of the compression tester. If you have a friend with a similar bike then you can check his and compare it with yours.

Regardless of the reading, now remove the tester and then put about a couple of squirts (teaspoon full max) of engine oil into the cylinder head and then repeat the compression test.

If there is a noticeable increase say 20-30 psi then I am afraid its your piston rings or valve guides which are leaking pressure, the oil temporarily sealed the leak and gave a higher reading.

BUT if the pressure is about the same then its probably not your rings and like I said earlier it could be steam caused by water vapour in the engine burning off at start up. If you smell the smoke what does it smell of?

Hope this helps,

White smoke coming out exhaust

White smoke! If your bike is water cooled it's not good. Check your oil. Just look at the dipstick after a short ride. Is the oil foamy looking? If so water from your cooling system is making its way into the crankcase. Unfortunately this is major.

2008 yamaha r6 white smoke out of exhaust and when i cut the bike off it will not start again

Sounds like it overheated. White smoke can be oil but, with it not starting sounds like coolant and it overheated. Take it to a repair facility for confirmation.

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.

Exhaust pipe comes out white smoke when start bike on side stand

Continuous or just for the 5-10 seconds.
If continuous you may have oil seeping past your pistons oil rings or valve guides oil seals.
Check your spark plug see if they are fouled badly (covered heavily and oily) or just covered by oil and sooth lightly.
If 5-10 sec it is normal as the engine is heating up there are normally a little oil seeping past the seals.

Pop noise with thick white smoke from front end,

sounds like you might have a cracked cylinder and oil puddled up inside over night and when you started blew out through the exhaust. White smoke means smoke means gas ,and blue smoke means both..if you cracked a water jacket your oil will look like a bubbly milk shake.....take a look at your oil.

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.

Whaite smoke at idle

honest advice. I recently obtained a 1984 RR 250. It has 19000 on the clock. I replaced all the obvious components like battery plugs oil filter, sealed tank, cleaned petcock. It starts up and runs smooth too. My problem is this..... ... Whenever I start the bike, especially after its been sitting (say overnight) and even more so when Its colder outside, it releases a grayish white smoke from the exhaust. It almost smells like an old gokart or something. It will eventually dissipate, but i can still see faint smoke. Usually if its colder outside, it hardly goes away at all. So what gives?? Is it bad valve stems? Bad head gasket? Cracked valve head? Bad piston rings? Im really stumped, and I would like to fix this myself (even though ive never been inside of an engine but I learn fast! especially being a biochem major!). Id rather not get the shaft from the two local stealerships/mechanics. IF anyone has any knowledge of or experience with this problem I would appreciate any input you may have. Thanks very much,It's normal for white smoke to appear out the exhaust in colder temps - there is a small amount of water present in gas that gets burned in the combustion process and is released as vapur, or white smoke, out the tailpipe. Other causes of white smoke are blown head gaskets on liquid cooled bikes - but as yours is air cooled, this obviously isn't the problem. Next time this happens, check the outlet of the muffler closely... if you see lots of water droplets coming out with the smoke then I'd suspect cheap too low octane of a fuel. Try a higher octane to see of the problem goes away. White smoke can also be caused by unburnt fuel. If a spark plug is erratic in operation (ie: misfiring) it can fail to ignite the fuel/air mixture in the cylinder under compression forces and shoot it out the exhaust valve as white smoke. One other cause is the engine running too lean. As your bike is fairly old, I'd check the condition of the carb rubber intake boots. If they are cracked, this can allow air to get sucked in and lean out the mixture, causing white smoke. Another clue to a lean engine is that it will run very hot and the headers/exhaust pipes will turn a deep blue.,,,
