2004 Polaris 600

[Darrell Larson]

I have oil in my air cleaner chamber. It runs just fine at idle but when put under load it starts to run really rough and starts to cough up oil. Any suggestions as to what could be wrong prior to taking it in to get looked at?

Just don't want to walk in and say fix it. Thanks in advance. Darrell.

did you roll it? its normal for some oil to drain into the air box when you roll.

clean the airbox. Top off your oil. Make sure the air filter is not oil soaked. If it is, replace it if it's paper or clean it if it's cleanable.

There is also a drain tube and plug on the back of the air box that basically goes to nowhere you could get some of it in there as well so you might need to clean that area as well.

rundrave: No did not roll it, my age kind of prohibits that from happening (61). I will clean the airbox and yes the air filter was soaked with oil, I will replace that and will locate the drain tube to see if that is in fact clear.

Thanks for the response, at least gives me a starting point. Later Darrell.

ps: Never had a wheeler before this is all knew to me. Internal combustion engines so many things could go wrong, just thought I would throw it out there and see if anyone had a similiar problem.

I had the same problem with my 500ho. Found the carb was leaking gas into the crankcase and it was over filled. replaced the needle and seat. good to go.

SemperFi,

If you've never had a wheeler prior to this and you just picked this machine up(?), there is a chance the previous owner either rolled it or atleast had it on it's side. Not to cause any concern but it may be worth looking over for any other issues related to a rollover.

[Darrell Larson]

fishingtech; thanks, sounds like something I should look into. I will check on the fluid levels, should be able to smell the gas if it is in the oil. Good place to start. Thanks again for your reply.

LEP7MM: picked up the wheeler from a friend of mine in the Cities, was his wife's, they had twin wheelers. I have owned it for two years. Ran just fine until just recently. Thanks for your reply. Darrell.

Too much oil on a recent oil change? Excess oil from on overfill goes in to the carb via the breather tube. Some of these engines are tough to fill correctly as there are a dry sump or scavenge type system. I don't know about yours...

Does your Sportsman backfire or idle rough?

[Darrell Larson]

MNexpoler: It idles fine, does not backfire. I can sit in the garage with it in park and increase rpm's with no problem, take it for a ride then symptoms such as misfire [no backfire] almost like it is starving for gas or flooding, that is why I opened the air cleaner compartment to see if some vermon built a nest, that is when I discovered the oil. Any help would be appreciated.

The oil was a major concern of mine, where and how did it get there, not asking you, just a concern of mine. Thanks for your interest. Darrell.

Do you transport the machine often or does it stay on one piece of property? I've seen a common practice of transporting ATVs standing on end to get more machines on a trailer.

It's not recommended but I see a lot of people do it.
