I know that this is a Busa Web site and I am a visitor, but here is the tank I made (Got a recalled tank for free from someone that bought a Canadian bike) and it holds a little over 2.5 gallons and very low on the bike. Actually I sit on top of it!
As you can see, my seat did not fit either and had to make it fit also.
Just in case I did want a CF Tank, this one is made in Hawaii!
Of course I am gald that he makes tanks better than he can keep his thumb out of the picture!
Here is a little peak under my cover! Opened and closed.
You mentioned "Ready for Bear"? Well here is the long and short of it, Bear Velocity stacks that I use to hold the NOS Spray Nozzles.
The Gold ones in the above picture are the short ones. I am still working this out also!
