    Ugh... thought the real stuff would shift it easy enough, presumed it was the California nanny state that was holding it back - sorry about that

    I have also read about Aircraft stripper being used where MEK fails.

      Good suggestion. I used pea gravel on one tank and while it worked, sharped edge stones like you used would have been better.

          Sorry for the silence, I've had very little free time lately.
          The tank Sat until tonight (almost 2 weeks) with the MEK in it. I've been out to shake it every so often. I drained it tonight & will be switching to acid tomorrow. I did get some stuff out & a glob of the Kreem liner about the size of a large wad of bubble gum.

          In other news, I hooked up a small fuel tank that I had, and put about a 1/2 quart of petrol in it. Choked it, twist o the throttle, and a quick shot of starting fluid.... And it's ALIVE!!!!

          Now to just get this tank fixed!!!
          Thanks for the interest, fellas!

            Well that's good news. I'd avoid the starting fluid though....

              Yeah, I just used a quick shot. It has been sitting for 2 years without a tank & dry carbs.

                Hope you are checking inside to make sure all the old liner is out before derusting.

                  I'm still working on the liner. It's a bugger to say the least!!!

                    Here is a pic of some of the old Kreem liner. All the stuff in the top left corner came from around the filler neck. The other wad & few large pieces were fished out when I was draining the MEK on the 1st round.

                    The MEK combined with a Brillo pad on a stiff wire seems to be working well.

                    We will see.

                      Well, it's done. Now I wait until the liner cures. It's not as easy as a '71 Army Jeep. I used the POR 15 tank kit. I wish I would of had twice as much sealer, towards the end, it was hard to tell where the fluid was at. The people that designed a '78 1000 tank sure never considered someone putting a liner in it one day.

                      I figure that 2nd to worse case scenario, this buys me time to find a good tank.

                      Thanks for all the help guys. Maybe next weekend... I ride...

                      Maybe.

                        Update. Tank is on, waiting on a new grommet & bolt for the rear of the tank (completely forgot that I didn't have one) and fill the front forks... then I should be mobile! It ran tonight, on its own, with fuel that I put in the 78 skunk tank I bought from Salty!!! Soon. Riding soon!

                          Congrats - sorry it was harder than thought. In a pinch you can use washers and some fuel hose / water coolant hose to make a mount at the back. I rode 2000 miles through baja with the 1100 tank fixed like that.

                            Yeah, thanks Salty. Now my problem seems to be fuel delivery. It will only run on full choke.
                            Im guessing I need to do the carb tear down that everyone is so violently adamant about doing.
                            My bigest problem is that I don't have a gauge to set vacuum with... And I don't have $ get one now. We will see.
                            Thanks.

                              Yes sounds like it. You can make a vacuum gauge for a few bucks, plenty of tutorials online. To get it running and ride it you can do it statically anyway - you are not going to be that far off & it will probably change anyway once you've run it for a bit!

                                Yeah, I spent $22 @ Ace Hardware today on tubing, nylon Ts, zip ties & ATF. The zip ties & ATF were the most expensive items. I just don't know how to connect the clear tubing to each carb. I will do some more research.
                                I also bought a can of Berryman's. (1 gal)
                                The carb clean up is in the very near future.
