I shall, not that it matters all that much with modern tires... my size of 712 are 6 ply as all others are 4 ply. Still waiting on Shinko USA to email me.
Have to agree, WTF did he get those pressures???
I don't know what your wheels look like, but the rest of us are not using tubes on cast wheels. I am also using the pressures recommended by Suzuki on the under seat sticker.
You should have noticed that nobody at the dealerships was born within the decade the GS was built. Don't trust them to have a clue about how to fix anything on a 1970s-80s bike.

The 10 percent rule
The 10 percent rule
Now lets see if I remember.
Air up the tires to a given pressure,lets say 35 psi.
Take a 10 mile (15 km) ride.
Recheck the pressure,it should be 3.5 PSI higher.
Adjust pressure till you get a consistent 10 percent rise.

A lot of them aren't much better off with what they're selling today.

Answer from Shinko.... I am awaiting the comments to fly lol.
Hi Chris,
Thank you for contacting Shinko Tire U.S.A.
Both of these tires have a max of 41 psi cold. We recommend running the max psi on the sidewall whenever possible and never more than 5psi below for rider comfort.
We appreciate your interest in Shinko Tires.
Sincerely,
Kyle Kosberg

the motorcycle shop I had look at my rims said "no" to going full tubeless. I have the OEM rims for my 450. The tire guy said, no bead area, we won't install and suggested I not install a full tubeless. Said I would have to drill out stem areas for the right stem and pray a bead would seal. They would however install tubes, liner and same tires on the rims. Basically they are not wanting to take on the liability should something go wrong.
Tires change over the years, what Suzuki recommended in 1981 is not necessarily what is needed for 2017 tires. I will go off the tire manufacturer recommendation over suzuki on this one.
The 3.00 and 3.50 are 6 ply while all other 712 sizes are 4 ply, mine are a little heavier.
Any way about it, I'll stay in Shinko's range for my specific size.
tubes inside tubeless tires work fine. ...you will have a tubeless tire in practice except around the valve, because the tubeless is going to seal itself to your alloy rim anyways if it's clean. The alloy rims went tubeless within a year or two of yours. They are very similar.
as to tire pressure,
as to tire pressure,
. sounds odd to me. Like "We recommend running the engine at max RPM whenever possible"

While this is a decent method for track use it can result in running lower pressures than optimal on the street as it is hard to get tires very warm at all in normal riding, especially in cooler weather.
Sad but true.
That is perfectly reasonable for the shop to not be interested in converting to tubeless, but know that there are many here (myself included) who have gone to tubeless set ups and have no trouble with them. Less unsprung weight, cooler tire temps and less chance of an explosive flat compared to tubes. It's very worthwhile in my experience.
It is logical for the tire manufacturer to recommend the max pressure for all riding. It gives the most protection to the rim from road debris, provides the highest load capacity and runs cooler. It doesn't provide the best performance, though. You just have to realize they are in the business of covering their asses and not giving out performance tips.

No harm following advice from Mr Kosberg Shinko tech.
I have a much bigger GS with different size tires of course. My wheels have; "Tubeless" cast in the metal.
Still, such high pressures will give a hard ride with better gas mileage, but not heat up enough for sticking through steep lean angles.
At the race track we are all advised to use about 8% below manufacturer recommended pressures. Low pressure allows the tire to distort, and that distortion causes internal friction and heat build up. Hot tires stick better than cold tires.
Ride the way you like to ride, so will I.
