Nice drag bars! I like the way the Valk looks without the tank. Too bad you need it...
They do make belly tanks!
That's a WICKED COOL idea

, shave down the real tank as much as possible give it a minimal size kinda chopper small, mostly just as a filler spout for the 3 gallon belly tank. So the top tank might only be a bit over a reserve size,,

Good luck and I am sure yo will have lots of excitement good and maybe not so good.
