Ok so the rust in the tank looks like it is going to be an issue. The four holes are at the front near the cap and the single is on the right rear [emoji17]and I can’t see that being the end of it. What tanks do the American models have Steel or Plastic, the images of tanks on the various parts sites look similar so I’m hoping that another model 91 might be a match. Thoughts of the forum ??
Not sure about the rules in Australia regarding plastic tanks and on road usage if you are planning to run it that way. If not I'd look at a plastic one of the same years. Tank rust can be cleaned up, and the holes can be patched by a competent welder, but both will require a bit of work on your part.
I have been doing the vinegar rust treatment,so the tank looks cleaner and I can plug it with needit for the weekend away, meanwhile I will pop down to the local panel/tank guy, my main concern is in the long term putting tank kreem or such might be a wasted resource so I will start the search to find a plastic tank.

These will help out your tank situation. Use these instead of time and effort on that tank. [emoji16]
Yep, so you gotta spare that’s just laying around, I will gladly take off your hands. But just in case I will clean it up, lead wipe and seal till I find one. [emoji846]

There’s no need to show off lol
So give us your address if I leave now I could be there in 36hrs[emoji23]
After an exhaustive few hours and 20 phone calls I now realize that there a no tanks in Australia, next NZ’s turn, a interesting point is that I keep getting told that the plastic tank won’t fit buy the Australian bike wreckers ?

It’s the oldest form of body filler, most top end restorations still use in in place of plastic body filler or bog as we call it, once it’s on it’s on for good. We have J-B weld and Knead it but lead wiping is as permanent as never having holes.
Do you have apple cider vinegar? That worked well in a metal tank I did a few years ago from a Yamaha QT50. One just needs to do a baking soda version afterwards due to flash rusting.

I used cleaning vinegar as it had the same 4% acid as apple cider vinegar and due to the fact that ACV in large volumes is difficult to come by over here, baking soda flush afterwards and dry with the heat gun. My downfall might have been that I didn’t throw nuts and bolt down its throat initially and give it a good shake, in saying that the flaking was minimal after I did.
Mine was nowhere near that bad, but I still two cycles.
Yes Yes It Is, going to try a
“ professional “ treatment/seal and hope for the best and maybe eventually [emoji16]someone will sell me a plastic tank
Fingers crossed.
One thing for the novices(me) to consider when sealing a tank for the first time on the Sr metal tank is the cross over between sides will get blocked [emoji849][emoji17]
