XP4 900 Using Oil and hard cold start issues

I have my wife’s 2012 RZR XP4 900 that has recently started using oil. I first noticed it about 4 rides ago that when I decelerate it will smoke blue (OIL) usually in an automotive situation this would be contributed to bad valve guides/seals. I’m thinking that this will still be the issue with this type of cylinder head. It used 1/2 Qt of oil on this last dune trip in about 50 miles of duning which was almost 70% WOT. but with lots of on/off 100% throttle.

Second issue which has come on slowly over the last 6 or 7 rides was hard start cold issue. Started out taking a few cranks to fire and stall until eventually idling by itself without adding any throttle input to steadily getting tougher to start without adding throttle to what we have now is almost not starting at all without holding WOT and cranking 10-20 times. I used to be able to play with the peddle 1/4 to half and she would light up but now it wont start anything less than WOT.
It sounds and cranks like it has no compression when dead cold so I pulled the filter off and had a buddy crank it while I watched and listened to the intake. It was spitting gas back out the intake towards the air filter cold.

My automotive experience is telling me that the guides and seals are wasted and need to be serviced for the oil consumption, And the valve lash is now too tight as the valves have sank in the seats enough to loose the gap needed to have a seal at dead cold and that’s why It cranks like its low on compression and spits gas back out the intake cold.

I know that there is a similar thread by another guy here in AZ but his has a knock mixed in the works and I didn’t want to hijack his thread. Thanks for understanding.
I would also like any recommendations on a cam choice at this point since the head will be off or am I going to spend $ on something that just isn’t going to gain any performance? Do you guys think I’m on the right track with what’s wrong with Pinky?
