Raptor 350 blue smoke

Ok guys so I bought it 3 months ago so and my friends say that it blows a little bit of blue smoke when I let it the throttle in 6 gear. Is that true, because I had it for 3 months and ever time I check the oil it’s the same level

Check the spark plug for oil fouling, it would look wet, but i think its such a small amount of oil you wouldn’t see the difference, you could also do a compression test just to rule out the rings, or it could be valve stem seals

Is it beat up can you tell it has hours and hours? Sounds like a new piston in rings in the near future. I would not ride alone in long trips with that quad. Could leave u stranded and then the boogeyman and crooked hillary will scare you from the trees in the trails.

i think rings are good then, when you cold start it does alot more noticeable smoke come out? And as it warms up does it go away? And hows the spark plug look?
