Graphing results of performance test and finding area under curve

[dirtboi22]

Problem statement, I am calculating the time it takes for my motorcycle to reach 55 miles per hour, through its engine Horsepower, Torque, transmission gearing, and sprocket gearing.(chain driven)

I am using the equations:
F=[mass/g]*[dV/dt]
dt=[mass/g]*[dV/F]
t=∫[mass/g]*[dV/F]

F=[(torque*Drive ratio*gear ratio*primary drive)/(tire radius)]
V=[(RPM*tire radius*2pi)/(Drive ratio*Gear ratio*primary drive*60)]
F'=[mass/g]*[1/F]

Using these equations I plan to graph Force Inverse, F', vs Velocity. With this graph I will find the area under curve from 0 to 55mph. which should be Time?
I am using the rpm range of the engine, 2000-9000, and I am find F,F', and V for all gears of transmission, 1-5.
Does this look correct, equation wise?
I recently met with my Calculus II teacher and he said it did not look correct. Any help would be great, I am a mechanical engineering student and I am very curious. I know this is an in depth question, I am simply asking if my equations look correct and if graphing Force Inverse vs. Velocity will be correct in finding area under curve, time. Thank you, I can add additional info if needed!

What is mass / g supposed to represent? After all, F = m * a

SteamKing, Mass/g is mass over gravity, It represents the weight of the entire machine on the the driving wheel, being that the driving wheel is the cause of acceleration? However Maybe this is not needed. This equation is actually the reason I posted this question, I am not sure if F=[m/g]*[dv/dt] is correct or applicable to the problem..

I had spoke to one of my school advisers, who actually gave me this equation. It was very short and I honestly felt like they really didn't care. I had used this equation and graphed force inverse vs velocity, and the area under the graph had actually represented a fairly accurate time for the machine to reach 55mph. However I have began to think it is wrong, being that my teacher said it made no sense. If I was looking to find the time it takes for my motorcycle to reach a certain velocity what would I need to graph, so in which the area under the curve equals time?

If you are using the weight of the motorcycle, use w to represent the weight, rather than m, which usually stands for the mass. w/g = m.

If you are using the weight of the motorcycle, use w to represent the weight, rather than m, which usually stands for the mass. w/g = m.

You are most definitely correct! I apologize, with it meaning weight and not mass, do my equations look correct?

Just to clarify for everyone, I am using the equations:
F=[weight/g]*[dV/dt]
dt=[weight/g]*[dV/F]
t=∫[weight/g]*[dV/F]
