I was riding my 2013 m8000 this weekend and halfway through the day my sled got a terrible bog. It would not go above 58-6000 most of the time. At lunch I pulled my plugs and the clutch side were dirty so I replaced all 4. No change, so I just ride like that the rest of the day. Once in a while it would open up, but mostly 5800 was max. It is stock other than a can with 2700 miles. Pulled the power valves today and cleaned them, they were dirty but seemed adjusted correct. Where else would I look?

Just dirty can do that if sticking.
Your stated rpm is right where dirty pv would act up.

Check the reeds, You might have have a petal that has a large crack but has not broken off yet. 6000 is about the spot that a partially stuck or broken petal causes the cylinder to misfire.

Ok I'll look at check spring and reeds. Do I need a scope to see all the reeds? It sounded different as well, deaper almost like a 4 stroke.
