Saw it, fell in love, bought it. While I'm working with Junior ultimately on a set of small split tanks for my XS650 rigid, they're going to be fairly small for ripping around town. Was thinking I'd like something bigger for longer trips that I could swap out.
Plan is to mount the tanks on L brackets welded to the backbone, so they just float there. The backbone will be exposed and the brackets welded to the underside of the tube so they can't be seen. This BSA tank will need some bungs welded to the underside to mate with the same brackets, but it's nice and flat so should sit just fine.
Anyhow - was perusing looking for larger capacity tanks and stumbled across this BSA C15 tank. Impulse buy. Dent free, rust free, petcock and cap included. $125. Not cheap, but not bad for a clean rust, dent free tank with cap and petcock. Saw the same tank all rusted up sell for $60, so this seems OK.
Upon doing some research I find it's only 3 gallons, so not a massive jump from the likely 2 gallon small tanks, but 50% more is 50% more. And if not for this bike, maybe it will go on something else some day. Just spoke to me, and it's tax refund time
