I realize it's not what you are asking but I use the rubber exhaust mounts on my roadster tank

As Baz plus maybe one buffer, but if you want to use the buffers and studs then you put enough on so once the nuts are tightened up the tank sits correctly.

One exhaust mounting causes the front lower tank seam to contact the support arms there not physically tall enough... so I'd have to place a rubber washer beneath
I'm using the exhaust mounts at the rear OK

Me too. Plus one each side between the bracket and big flat washer.

I found that same issue when trying the iso's on the front but like you, I have used them on the back. My tank is a re-pop and not sure if its shaped right or if I put the foam cushion precisely where it needs to be so that might be causing the issue.

Don't let the wings support the tank or you will break them, don't ask. The wings should just support the tank from flopping around and the thickness will vary bike to bike, tank to tank. The main tank support comes from the pad on the main tube, IMHO. For my worn out pads in both places I used cut up flip-flops. It's a very nice substantial material and easy to shape and cut. Comes in colors and cheap too, you can usually get a couple pair or more at the dollar store for a buck or 2.

Anyone else call them Zories?

Sometimes, I usually refer to them as Thongs....

DogT · Nov 5, 2019

I think I picked that name up in Taiwan. I lived there in the 50's. May be a Japanese takeoff.

I remember my mom calling them Zorie sandals when we were kids. Almost 60 years ago.

My mum called them Commando tank washers....

I wrapped the backbone of the frame with two pieces of 1/4" neoprene from one of my old wet suits.
The tanks slides on in a smooth and snug manner and the spine of the entire tank is supported by the frame, not sitting on the four studs.
The rubber washers were added accordingly. to keep it in place...works nicely.

Many thanks for this ...good reasoning

I also added a 1/4" plate below the wings for more support. I also got rid of those hateful nylocks on the tank front studs and used lock nuts. That way I can adjust the tension on the wings to my desire too. You can see it here, I used blue flip-flops, even for the front mount spacers.

The 1971-on models have the inverted 'U' shaped coil bracket bolted to the underside of tank brackets so don't need a plate.

Do you think using a pink Flip Flop will make any difference??

Yes.
They won't listen, will not cooperate, always tell you are doing it wrong, and your tank will always wonder if the pink makes it look fat.

Use blue, or black.
