Bigger gas tank

[cityslicker]

Ok. It's a 1981 xs650 special. I want less gas sstations in my life. Looking for bigger tank options. Anyone know place that sells a bigger gas tank for this motorcycle? Any other motorcycles tanks that I can buy and swap out without welding?
I saw something in the thread about an xs1100 tank fitting my xs650. Anyone care to help me with this.

XS1100 is no go. You can make a XS750 standard tank fit if you reverse the front mounts and modify your seat.
The XS650 standard tank is slightly bigger than the 3gal Special tank. You can source a new one at MikesXS and it’s a direct bolt on. It requires two petcocks or a blank off plate -easiest option.
