I've just bought a used 2010 500 ho from a dealer. First problem 3weeks after I buy it, I have to buy another one and I just install it and it cranks fine still playin with idle and choke but when I drove it today it would crank n idle fine but if I give it gas it dies I did this 2 more times so I pulled the seat off and opened the breather box it had oil in the box please help

 

Check oil level or drain the oil tank if it smells like gas or even if you have doubts,drain it as you're just talking about two quarts of oil and a filter. If the oil does have a gas smell to it,the carb may be flooding into the cylinder. This can cause excess gas/oil to fill the air box. May need a carb kit.https://www.ebay.com/itm/POLARIS-SCR...hUGdHy&vxp=mtr This kit fits the 2010 500 also. Hard carb to set the float level,but this article on a similar BST40 carb shows you how.The BST-40 Bible | Adventure Rider
