I really like the flat bottom of the 48 tank and how low it sits but switched to a 3.3 gal nightster tank for the fuel capacity.
I have looked and looked with no luck for a 3.3+ gal tank flat bottom tank.
Does anyone know of any? What about taking my stock 48 tank and stretching and widening to increase capacity while keeping the same look ?

 

Just google large capacity peanut tank and you will find different options.

Thanks, I have. All I have found has a rounded bottom like the nightster tank that I have.
Dont get me wrong, It looks fine. But I really like the true flat bottom of the original.

 

Awilson40, man, I wouldn't recommend you to stretch and widen your stock gas tank (doing so may cause the gas tank walls to thin). Spare it and have another one (a bigger one) built for your ride.

 

So there's quite a few 'semi-custom' options as presented previously.
What I personally would like to see, for lack of a better description,
is a 'Cole Foster' inspired King tank that is in the 4.5-5.0gallon range.
I dont care for the 'lifted' tank kits, so what I'd be looking for is
keeping the 'top' of the king tank the same, but dropping the
bottom down to just above the rocker boxes....

T. (yeah, call me strange)

 

Not strange at all, just what I'm looking for also
