Dwight, I'm no wrench but here's what I think based on the posted specs.
The quoted T-Bird max HP & Torque specs are very similar to my Victory bikes. I don't know how to post performance curves here but you'll probably find that redline is somewhere north of 5K - 5500 RPM.
My 1600cc bikes seem to be really happy running between 2K & 3K. If I need to acclerate really hard between upshifts I might see 4500 RPM.
