250-500cc Ims gas tanks

Figured a long shot but is Ims making new Ims tanks yet specifically for wr250/300?
When I bought my 3.4 gallon one a couple years ago that was the only one available. I would have bought a larger one in a heart beat if available.

Then stumbled on this. Anyone know if its knew or did they just figure out an existing 3.9 gallon tank would also work?

I believe that it is a larger version of your tank.
