And yes check the CVT worn belt and weights will slow it down quite a bit.

If tight the motor would loose a quite a bit of power due to loss of compression. Alleyoop

Yes, do a valve adjustment first before anything else it may surprise you on the results. And also at 5000 miles I would also check the weights they probably have flat spots on them and or binding in there.
