Tires today are made of diff compounds than the original tires on our bikes were 20+ years ago. Today tires are more durable and can run at higher speeds, so I would go with what the recomended pressure on the TIRE itself shows.

I believe the pressure stamped on the side of the tire is the MAX pressure, not recommended pressure.A good question allways gets a good answer, so I hope. Do you inflate new tires to recomended pressure in manuel or whats listed on the sidewall of new tire? Thats asuming that new tires are the same size as listed in manuel(Stock size). Weight rating for heavier loads? Whats the safest way to ensure proper pressure?Safety First.

Why do I have to check my tires inflation pressure?
Low inflation pressure stresses the tires and heats them. It may even lead to blow-outs and tread separation. Moreover, it contributes to premature tire wear and decreased fuel mileage. That's why you should always be sure to have your tires properly inflated. Also make sure that the inflation pressure matches the one indicated in your motorcycle manufacture owner guide.
Pirelli
From the Metzeler motorcycle tire site:
INFLATION PRESSURE
Many tire damage result from incorrect inflation pressure. Furthermore, the inflation pressure has a big influence on the riding qualities of a motorcycle. The inflation pressure recommended by the motorcycle manufacturer can be found in the bike's manual and is usually written on a sticker on the rear swingarm or chainguard. Set the suggested inflation pressure on cold tires before riding. During service the tire's warming-up causes a pressure rise that must NOT be reduced.
Check inflation pressure once a week. Increase rear tire pressure by 0,2 bar / 3 psi when riding with a passenger or with very heavy load. Insufficient inflation pressure causes tire flexing and overheating that may lead to internal damage. Overinflation impairs riding comfort and stability and can result in uneven wear. When checking the inflation pressure, don't forget to lock the valve cap. Use a valve cap with rubber sealing.

Use the specs in the manual or under the seat (should be roughly 28 lb front 32 lb rear rider only / 36 lb rear rider and passenger for KZ650) ...
I kinda wonder if they're referring to modern/newer motorcycles when makeing these recommendations.From the Pirelli motorcycle tire site :
....Also make sure that the inflation pressure matches the one indicated in your motorcycle manufacture owner guide.
From the Metzeler motorcycle tire site:
...The inflation pressure recommended by the motorcycle manufacturer can be found in the bike's manual and is usually written on a sticker on the rear swingarm or chainguard.....
My 81 KZ650-CSR lists 25 psi for the front & 22-25 psi for the rear.
There's no way I'm going to run new GT501s that low.
