<div dir="ltr">I think the cheapest stuff you can buy is soaking in vinegar, people throw nuts and bolts in to shake the rust loose. But for the money and best result, a trip to the radiator shop is the way to go. I took my roadster tank to a radiator shop to be cleaned. During cleaning, they found a bunch of holes which they fixed and resealed everything. About $100 out the door. Vegas dollars though, not Bay Area $$, not sure what the exchange rate these days are. ;)<div><br></div><div>Kris.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Sep 14, 2016 at 12:58 PM, Gary McCormick via Datsun-roadsters <span dir="ltr"><<a href="mailto:datsun-roadsters@autox.team.net" target="_blank">datsun-roadsters@autox.team.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="color:#000;background-color:#fff;font-family:garamond,new york,times,serif;font-size:16px"><div>Apologies if this is a repeat.

with the noxious contents of the gas tank in a Roadster that has been
sitting for years has been a common topic in this forum; I now have that
issue with the <i>other</i> non-running vintage Japanese vehicle in my
garage, my 1972 Yamaha LS-2, which I have rolled out and am going to get
running for the first time since ≈1981. I don’t plan on riding this
little 100cc two-stroke twin very often, or very far, but it was my
first street-legal motorized transportation (a 16th-birthday present),
and I think it deserves to see the light of day again. And maybe getting
the Yamaha running will finally inspire me to finish cleaning out the
garage so that I can get the 1970 2000 Roadster back on the street.<br></div><div dir="ltr"><br></div><div dir="ltr">Anyway,
there is a small amount of liquid in the bike’s two-gallon gas tank;
pretty smelly stuff, too. What have any of you done when it comes to
cleaning out and de-sludging a gas tank? Is there a particular solvent
or cleaner that works well to remove the remnants of decades-old
gasoline? I haven’t looked into the carburetors yet, but I am assuming
that I will have to clean them up internally, also. The petcock has been
closed all these years, but there was certainly some amount of gasoline
in the float bowls of the little twin Mikunis.</div><div dir="ltr"><br></div><div dir="ltr">Thanks in advance for your advice,</div><div dir="ltr"><br></div><div dir="ltr">Gary McCormick</div><div dir="ltr">San Jose, CA</div>1970 2000, SRL13291</div></div></div></div><br>______________________________<wbr>__________<br>
