I'll be starting my OCC project soon. It appears there is enough room under the seat, on top or at the rear fender to install a small gas tank, as I have seen on pictures of other (non occ) builds. I maybe trying to avoid the big ole gas tank on the top bar. You cannot install a rear rack, or I don't want too. I am looking for at least a 2 quart gas tank, cylindrical, and to fit horizontal. What do you suggest? Should I attempt to make one? What have others have found to use? Is there a supplier of small gas tanks? I know it has to have an outlet, I would like one taped so that a petcock and/or fuel filter can screw right into it. Thanks for the suggesstions.. my project is going to start soon. I got a real pretty, immaculate OCC Stingray, the Barry mount from Ebay, front forks with fender and brake bosses, dual brake pull lever with built in thumb throttle for right side. Going to get custom occ exhaust from barry on ebay, then the custom sprocket adapter from the maniac. Probably going to get the Pirate PK80 kit, as I see all the new stuff going to goto that engine so it has somewhat of an upgrade path built into it.
