Question 03 Yamaha 1300 won't run top speed

Hello everyone, I am having a very complicated issue that has been very tricky. So my fuel injected 1300 runs top speed for a minute or so then dips down to 45 MPH. It seems to try to hesitate and bog down. It will run full speed for a minute but not long. The compression is great, new D plate, new fuel pump, new injectors, new catalytic converter I am running out of things to replace. No matter what is done it won't consistently run over 45. Any thoughts?

Did you use the chip on the temp sensor when you installed the d plate ?
