Low power/ top speed.. How to fix?

Your bike will act exactly as you describe if there is low compression.
Anything at or below 120PSI with wide open throttle during a compression test is too low.
That would be the FIRST test I would do.
Then follow up with a vacuum test IF the compression is at or over 120PSI.
Your vacuum should read at 20inches.

The issue can then be in the CVT or ignition timing if not in either of the prior tests but I suspect compression.
You can get a good compression tester from Carlisle for about 40 bucks, and it is a MUST have tool. Even more important than a BFH.
