I checked with the local salvage yards for bike tanks--- Yamaha was a favorite. I was looking for a later year R-1 tank and settled for the FZR-1000 tanks. Just make sure you get two of the same make tanks to match the bungs you cut up and weld into the body.
I paid approx $ 50 dollars per complete tank. Some quotes at yards were up to $125 each tank so check around. When the bikes go down, the tops of the tanks usually never get damaged. If you can get the keys, great. If not, the local locksmith picked and re-keyed for $10.
Yamaha, Honda, and Suzuki all are almost the exact same style and diamater of fuel door. Any one of the go fast street bikes should work the same.
Good Luck
