Bought a 2008 yfz 450 new 5 months ago and since oil change has been smoking blue smoke, oil. Smokes when revs up but not idling or riding rev up and smokes. Rings or valves?????

I have heard that the valves have to adjusted fairly often.

Could be rings, valves, or a head gasket. It is a bit odd that you would be burning oil in a quad that is that new. Have you been doing services regularly? If so, and it is still under warranty, I would let Yamaha deal with it.

Hope it turns out well for you. Please keep us posted with the results, I am curious to know what they find.

i would first check oil level
you need to run quad for a 3 minutes and let sit for 2 minutes before checking stick
excsessive on off throttle use can cause fuel to run through rings and elevating level if so replace oil
