oh i wouldnt say its crusty. no brittle metal..no holes...its pretty solid...tank was not original to the bike. The bike was pieced together by me. When i got it, it came with a broke frozen in place neck, fork screw hole was plugged up and truss rod and fork ends were rusted beyond repair, neck was beat up and warped. bars were warped. I didnt know the extent of the damage till i got it as the seller didn't specify damage which is a pet peeve of mine. Rack was missing, fender reflector was missing, seat cover was weak and falling off, drove for miles to get a replacement fork but no truss rods as they are long due to the lock feature. Tank does have best offer. Repro tanks sell for the price of an original these days and with little effort this one will go nicely on a nice original paint bike so figured it deserved a little respect.
