Motorcycle Top Speed Help!

I am installing a new engine in my CL175 and it has different gear ratios! My goal is to be able to go 65 MPH at a comfortable RPM.

The ratios:
Initial/Primary 3.33
First 2.769
Second 1.882
Third 1.4
Fourth 1.13
Fifth .96

Front Sprocket 14
Rear Sprocket WE DECIDE!

The rear wheel circumference is about 80in. I may be able to install a thicker rear wheel.

The bike redline is 8,500 RPM.

I have already done the calculations, but I want to double check.

The original gear ratios were:

The ratios:
Initial/Primary 3.7
First 2.769
Second 1.882
Third 1.45
Fourth 1.173
Fifth 1
Sprocket 2.5

Redline 9,500 RPM
