Well maybe I'm a little color blind (hehe). I don't think it's moisture, I mean where would it be coming from since this quad isn't liquid cooled? The smoke does have a blue tint and definitely smells like burning oil. I pulled the plug today and it was a little wet with oil. Are there any products out there (like an oil additive) that would reduce the smoking long enough to get a little more use before replacing the rings and/or stem seals? Like I said in an earlier post, I just bought this quad a week ago so my 11-year-old son could go on some light trails rides with the "ol man.

 

Welcome to the forum BigD71! [img]i/expressions/face-icon-small-smile.gif[/img]

The first 8 letters in my '04 Yamoto 150 are WINXCGZH if that helps. It has no reverse and a auto choke. I would try 30wt non synthetic oil and see if it helps any. If that doesnt help and if it isnt smoking too bad just ride it.

 

you just need to ride it hard and burn out the carbon deposits and the smoking will go away...
