Hi,

Evapo-rust is one option. Or...

Thank you for your indulgence,

I looked at these links and noticed that in the last one, the Kawasakimotorcycle.org link, one poster mentioned that he used a Bill Hirsch product.

This is the one that I found long ago but have not tried as yet. I posted this link several times: http://www.hirschauto.com/prodinfo.asp?number=CRK-01

Bill Hirsch primarily sells items for restoring old autos, primarily Packards, and such old cars are vexed by the same tank problems as our bikes. If you read the fact sheet, he claims that his tank renewal kit (acid etch, cleaner, and liner) is the only one that is approved by the FAA for use in aircraft. This sounds very impressive to me!

I need to do this to my GS, but I really do not want to damage the nice, original paint, and I have yet to find anyone that can tell me if or how this may affect the gas gauge sending unit (do I have to remove it, fabricate a cover for the hole that this unit fills, and clean the sending unit seperately?)

Yet another project on the list to get to someday...

Yes, pull the sending unit and make a block off plate. I fabricated block off plates for both the petcock and sending unit using plate aluminum and sheet rubber. For the main opening I use a large rubber stopper with a hole drilled though the center for a long screw and moly - so the plug can be cranked down to seal off the tank. Having good seals is very important since it's critical to rotate the tank and leave the solution to dwell on the various surfaces of the tank for long enough to take the rust off - whole process will likely take several days to do properly. And some aquarium rocks or pea gravel really helps too so you can scour the metal surface.

That material would most likely be fine. I'm a fan of the POR-15 stuff myself.

i may be different, but i dont care about the paint on the outside. i plan on repainting after the tank is cleaned and good to go. i just dont like the idea of "silly putty" inside my tank. the bike came with a tank that had been "treated", and honestly couldnt if rust was in there or not, due to the color and consistancy of the "sealer". i ended up hacking the tank apart anyway, and what do you know, rust... and molasses.
