electrolysis, or muractic acid both can be done on the bike but easier out especially the acid and take the fuel gauge out???

Go get some Metal Rescue and let it do the work for you. Nothing works better and cleaner.

I just did the tank pull on my 81 and while it wasn't fun, it wasn't all that difficult. The only hard part I had was a plugged reserve line which I've finally resolved. I posted a big write up in TechTalk forum on it.

I used CLR and sloshed the tank, you could probably do the same without pulling it but requiring a lot more CLR. I think the muriatic would be cheaper (and seriously considered going that route even with the tank out and CLR'd due to the reserve not wanting to clear). Problem using the acid in the bike that I see is a LOT of acid being messed with right in the middle of the frame, electrics, etc. I'd be concerned enough to try the electrolysis method first if you're set on not pulling the tank.

FYI I found a good supply of tanks in various conditions starting at $5 with decent looking ones available for $80 or less on EBay.

An unloaded gun makes a pretty poor hammer....unless it's a HiPoint. (ME)
