Why does atv smoke

I don't really know what i could have done that would have caused it to start smoking. Does it only happen when the engine is cold? Or does it happen even after the engine has fully warmed up?

It is on your correct. Most of the time it is antifreeze burning when it is white. Otherwise i am not sure. Blue is oil and black is usually rich. When done, let the filter air dry for a couple of hours. Do a quick temperature check to see if the other cylinder if your four wheeler has multiple cylinders has a lower temperature.

You can do this by touching the exhaust manifold after starting up your quad. Listen carefully to your engine for any abnormal noise coming from the cylinder head s. You could be hearing a noise due to an improper valve clearance that needs to be adjusted. If so, your local mechanic can adjust it for you or you can do it yourself with the right tools. Unlike black smoke that is an unbalanced mixture of air and fuel, blue smoke indicates that your engine is burning oil through the cylinders and that the oil is escaping out of your exhaust.

The more often you have to refill, the bigger the problem is. But why does this problem even occur? Each engine has valves that open and close and are governed by rocker arms. As the valves go up and down the allow air and gasoline to enter the cylinder where they combust and distribute the power to the wheels.

Most commonly the oil seeps through because the valve seals are worn, cracked or broken. Here are a couple of ways to remedy blue smoke coming out of the exhaust…. This is where I would start if you have a poor maintenance record for your quad. While ATVs tend to be very resilient machines, things do go wrong, and one of the most common causes for concern is when your quad starts smoking.

Having had that feeling, I researched all I could to figure out what causes smoke so I would always have a good grasp on the cause. Why do ATVs smoke? Smoke can be an indication of bad cylinders, seals, gaskets or something similar, usually accompanied by gasoline or oil burning in the engine. Routine maintenance helps prevent many smoke-related issues, but a hard crash, bad cylinders or other causes may lead to serious problems in your ATV.

Fortunately, the color and timing of the smoke coming out of your quad will help narrow down the problem so that you can find a solution and get back to the trail. Because smoke is a good indication something needs repaired, be sure to check out our guide to the cost of most ATV repairs so you know how much it should cost and whether you should do it yourself.

When the ATV is is warmed up, the oil burns off better, and the smoke goes away. In this situation, it is best to do a compression test and a leak down test. Similarly, if the smoking happens primarily when you are revving your engine, that is likely a sign of bad rings. If the smoke is predominantly happening when you are letting off the gas, this could be a sign that rings are not hitting the adjacent walls perfectly. Now if the smoke stops when you let off the gas and starts back up when you hit the gas again, I would look at the valve seals first.

The color of smoke coming out of your ATV tells you a lot about what is causing the smoke. ATV smoke usually comes in one of four colors: white, gray, blue or black. White smoke is usually the best kind of smoke you can hope for. A little white smoke when you start your ATV can be perfectly normal. That is water vapor burning off. It is not a bad sign of anything in your engine, so long as it burns off in the first 30 seconds or so.

At that point, there is a decent chance coolant is burning in the combustion chamber. Coolant can leak into the combustion chamber to burn from a handful of problems, including a damaged radiator, damaged radiator hose, blown head gasket or a broken water pump. The easiest way to determine if there is a problem in your radiator system is to check your coolant level.

If there is a leak, the coolant will be low and you smell a sweet odor coming from it. You should then put your ATV in neutral and rev the engine. If you get a lot of white smoke, that is a bad sign something is wrong with the radiator system that needs to get checked out. You need to address it immediately too, as it continuing to run the quad in this condition will cause overheating that leads to more and more issues. I'm not an engine whiz, so i can't give a technical description. But, he said the engine may be leaving some residual sp oil after shut down.

And, this small amount of oil gets pulled thru the valves and burnt. Like i said, i don't know enough to give an accurate description. But, what he said seemed believable. Maybe i'll learn more then. I agree with a few of the earlier posts but I do know a little about motors. I can definetely tell that my smoke is black, which in return means, too rich. It only does it on start up. I also do know that people say you shouldnt leave your fuel on on a 2 stroke. In my opinion and with my personal tests I can turn my fuel off run the bowl dry.

Then when I get ready to ride. Turn the fuel on choke it just for a second enough to start then cut the choke off. This little method seems to work for me. It is kinda like the floats are sticking or the carbs are a little off from the factory. I think its funny though cause when we ride and meet here at my house everyone laughs becauser of the smoke, but after we get warmed up and I smoke their azzz, I am the one laughing.

Cant you tell that " I love my R!!!!!!!!!!!
