Hello boys and girls,
what could it mean when there is black oil on the end of my muffler? the quad has been smokin a lot lately. I thought it was running rich, then i look at my pipe and it has black oil on it?
Thanks

 

Remove your air filter and see if there is fuel or oil in your airbox. If so, stop leaving your fuel switch on after you shut off your machine or change your choke plunger springs.

Also change your oil if there was fuel in your airbox.

Couple more things, check your oil level, Overservicing your oil will cause oil to wind up in your airbox and make sure all your vent lines to your airbox are not kinked.

Have you pulled the spark plugs, and checked them? If they are oily...better do a compression check. Hows the oil level, overfilled?

 

There are only 2 possibilitys, overfilled crankcase, or worn rings. I hope it's the oil![img]i/expressions/face-icon-small-shocked.gif[/img]

i left my gas on for about 3 months over the winter by accident.i flush the oil and check all the vent and breather lines . all seems ok so far. thanks for the info.
