what might be happening with it burning oil and smoking really bad runs great in cold weather but not in warm

 

Well it could be several thinks like valve seals leaking , worn or sticking rings , valve adjustment ; or excessive carbon deposits builtup inside the combustion chamber which can cause the oil rings to stick when it warms up to normal operation temps !

What do you mean by it runs graet when cold but but when it warms up ?
If you means it doesn't smoke and run good when engine is cold this is a good sign that it could very well be exccessive carbon build up inside the combustion chamber.

Heres what i would suggest for you to try and its not to expensive thing either , change the engine oil and oil filter , clean and relube the filter , get a can of SeaFoam from your local auto parts store or local WalMart SuperCenter and mix it in your gas tank folling the instructions on the can ; it a great product that will clean the entire fuel system and also cleans the combustion chamber of the exccess carbon deposits and frees up sticky rings !

I've seen it do wonders on all type of engines from automotive to lawn mowers both 2 and 4 stroke gasoline and deisel engines , a 16 oz. can costs about $7.00 + tax ; and will treat over 20 gallons of fuel just mix it up in a gas jug and pour it into your tank and ride it's sure worth the cost !......

Hope it helps get the quad going using this tip , and welcome to the forums !..........

 

it runs great in cold weather. but when it is hot outside it run like has no power i thing it is in the carb. i now why it burns oil needs new rings. thnanks
