The stock tank can be mounted using L brackets that you can get just about anywhere. put the bracket on the bottom studs on the tank, and line the tank up on the bike how you like it and mark the holes on the bike frame where the L bracket it and drill 1 or 2 holes for it to mount to. I used regular self-tapping sheet metal screws, but any sheetmetal screw will work fine. Since my tank was the 1 gallon, not 1/2 gallon, the rear 2 gas tank studs where far enough down the frame tube that I could use the stock hardware to mount it, but most kit tanks are smaller, so you may have to use the L brackets on front and back mounts. Hope this can help.
