Hey trying to resurrect a 1983 GS 450. I have read many articles on removing rust and haven't had much luck removing rust from my fuel tank. Tried Evaporust twice and recently naval jelly twice which worked even better but still a fair amount of rust. Should I try something else, say eff it and try to re line the inside over the rust or take it to a pro? I'm in the Sacramento area FYI if anyone knows a good shop.

There are heaps of threads on here with many different ways... do some more searching and you'll find plenty of ways to do it :)

For me, I was happy just doing the POR 15 motorcycle tank repair kit, which includes Metal Ready which converts the rust and prepares the surface for lining.

All depends on how bad the rust is really...

There is LOADS of info on this topic in the archives.

Drop a bunch of nuts and bolts in there and some white vinegar and shake it around. Then fill it with the vinegar and leave it for some hours/days. Rinse, repeat if necessary. Rinse, then if you intend to leave it bare, coat the inside with oil or WD40 to prevent flash rusting.

This is just one of about 5 methods I can think of off the top of my head.
 
Yeah I have researched all over the net and tried what i think i could pull off without a functioning garage or workspace. I have seen the POR kit and am saving that for a last resort but the vinegar method sound like something I should try.
 
Vinegar worked for me.. Let it soak for a few days.. check on it day to day.. use a stuck or something to scrap the sludge and see how the metal looks underneath..

When it's ready drain the vinegar and pressure wash the inside till the water runs clean..

after that I blew it out with air to get most of the water out, dumped in half a quart of rubbing alcohol to help absorb water.. sloshed it around.. dump, repeat, blow in air again to dry then fogged with oil to protect it.
 
Electrolysis is fun and cheap. It takes a little time and effort but the results are well worth it.
