im choppin a bike i wanted to do somthing different for the tanks, thinkin about a dual tank setup but connect them with a pipe or tube at the lowest point to keep flow to both carbs even. stock tank has petcock on both sides feeding each carb. im thinkin about a artillrary shell/bomb shape one on each side of the frame and was thinkin about using smaller co2 tanks for paintball, anyone know if these are safe for gasoline? not sure what there made of, aluminum? sucks i dont have/cant tig, maybe some are steel?

or have any better ideas for things to use? id like them to be around 4-5" diameter im thinkin probly 1-1 1/2" length nothing forsure yet.. other ideas i came up with were small fire extinqishers or small air compressor side by side tanks which would make for easy modifications with my welder

hopefully i can get about 3-5gal of fuel capacity, bike gets about 50mpg

 

i think the side by side air compressor tanks would be great.
easy to find them pretty cheap on craigslist too

 

Pretty sure most co2 tanks are steel. I know my compressed air tank is..some are moly though..and cf.

 

use a couple fire extinguisher tanks, they are aluminum

nvm i didnt see you need steel
