Re: Gas Tank Liners
The tank supplied with the engine was rusty inside when I received it. Apparently, this isn't unusual. I removed the rust with Naval Jelly Rust Remover, which costs about $6 at many hardware stores. Worked great - removed all the rust with little effort on my part (just the way I like it). I didn't line the tank, but did put an inline filter in (always a good idea). I keep the tank full when not using the bike to prevent condensation. No problems so far with rust returning. The tank is still bright and shiny inside.
