Hi All ! I wonder if anyone can offer some advice. I have a ZZR1100 that Im working on that hasn't been started in well over a year (It's not running at the moment due to no battery, stale fuel in the tank amongst other things). The fuel tank is in great condition EXCEPT that it has a fair amount of surface rust on the inside. THE QUESTION - Whats the best way to remove the surface rust and scale from the tank ? I'm not even goint to TRY to start her before the fuel system is flushed and clean. THANKS for all of your Expert advice !
