Why does my honda rancher smoke

Join Date May Posts 2. Earlier this year i got into some water that was a little too deep. Unfortunatly i was about 2 miles from the truck and was working so i had to drive it back I changed the oil atleased 10 times and flushed it with diesel to try to get all the water out. Eventually i could no longer see water in it.

The problem is now it blows white smoke when i rev it up. I don't know about four strokes, so we'll need to get a good four stroke guy in here to hear what he has to say. But things like, does it smoke only when it's cold, or the whole time? Does it smoke more on when slowing down or hitting the gas? Because it's either a bad valve guide seal or the rings. I agree that smoking is probably only a topend problem. I can't see how the bottom end would encourage smoking. The could even do a compression test or leak-down test to see if the rings are in good shape, and they could focus just on the head.

I'm not an expert in this stuff, but mechanics with some knowledge should be able to go about this a little smarter than, "We'll see when we get in there. Never forget Semper Fidelis. Anyway the dealer said not to ride it smoking like that because it could wind up getting to the bottom end very soon if not already. 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.

When he returned it, he mentioned that the engine had smoked a little while climbing a hill. Rather than check it out, he kept driving for several hours. By the time I got it back, the head gasket was blown and the radiator ruined. Several hundred dollars later, I gave up and junked the car.

Black smoke is almost always an indication that there is something bad happening. Black smoke is a sign that your ATV is burning gasoline.

Gasoline burns in your ATV when the ratio of fuel to air is higher than usual. This is called a rich fuel environment, and it is not good for the ATV.

Fixing a rich fuel environment could involve a number of things. Hopefully, for your sake, it is nothing major and calls for a simple fix. Some of the easier-to-fix causes of black smoke include the following:.

The causes of black smoke you are hoping to avoid include the following:. Whereas black smoke means you are burning gasoline, blue smoke means you have burning oil. If you have a 4-stroke quad with blue smoke, or your 2-stroke is putting off an excessive amount of blue smoke, then you have a problem.
