Oil change question

Hey guys I have a sportsman 90 (my sons) and I went to do an oil change but all I had was yamalube for my 660. I used that and my quad wont stop smoking. Is this normal or should I get the recommended oil? Also kind of off topic but it doesnt hold idle very well its been this way ever since I got it new back in 08 is there any way to remedy this?

What weight is the yamalube.

Assume this is the 4-stroke 90 if you bought it new in '08, and not a left-over that could be a 2-stroke?

May need some carb adjustments to idle right.

The yamalube is 10w40 and we've always used 4 stroke oil and it hasn't done this before so I dont think its a 2.
