I am going to revise my lower wheel loads for 36/33 rear/front to also be a 150 lb rider on a 60/40 % split rear/front.  But then I will add on 48 pounds of cargo all on the rear wheel, which won't affect the front.  So I will get a similar loading range as you, though slightly different. 

I'm going to re-weigh the bike, and myself on it, and I will likely have to remove something off the front - maybe the windshield and/or maybe the slider bar in the front, as I suspect that at 175 lbs, I am already at or over the 313 lb GAWR for the front. 

If that turns out to be true (that I'm already at or over GAWR on the front), then that might have serious consequences for larger riders than I in that they should be very careful how they modify their bike - with special attention to minimizing any weight gain on the front.

I have substantially revised my tire pressure chart to reflect changes suggested by Lunkhead.  The only thing we have not ascertained completely is the weight distribution to the front and rear tires for 33/36 psi, as we have not weighed a new, unmodified bike, and I don't know whether Yamaha included the fuel or engine oil in its 542 lbs published empty weight.  So if anyone is in the central Texas area or is going through it on an unmodified Bolt, stop in and we'll weigh your bike to see how that distributes to the front and rear tires.

Revised chart below:   

I updated my chart to include the tire manufacturer's ratings.

Nice chart!  But how did you get a curve in your chart?  I only have two points (per curve) to plot to, which only defines a straight line.  I'd need another point or two to plot a curve.

More calculations:

Rider weight - FR / RR pressure:
175 lbs - 33.0 / 36.0 psi
200 lbs - 33.8 / 36.4 psi
225 lbs - 34.6 / 36.7 psi
250 lbs - 35.3 / 37.0 psi
275 lbs - 36.0 / 37.3 psi (front limit)

Passenger/cargo weight (over rear axle):
For every 49 lbs - add 1 psi to rear

Rear weight limits at GAWR:
245 lbs w/ light (175 lb) rider - add 5 psi
182 lbs w/ heavy (275 lb) rider - add 3.7 psi

Lunk, is this for C-spec or the other models?

Gotcha

This is what I get for the C-Spec:

125 lbs - 33.0 / 34.7
150 lbs - 33.5 / 35.2
175 lbs - 34.0 / 35.6
200 lbs - 34.5 / 36.0
225 lbs - 35.0 / 36.4
250 lbs - 35.5 / 36.8
275 lbs - 35.9 / 37.2
