Will it rev cleanly up to redline in lower gears?
As noted, a blocked intake snorkel will cut your power as the revs increase.
If the tank is not venting it will run fine after sitting a while, then slowly lose power as you ride.
You could drain the float bowls into something and take a look at what comes out. Do that with the gas off. Also pull the line off the petcock and confirm that you are getting a good flow of fuel.
There are also screens and filters in the fuel line that could be partially clogged.
