A classic! The onus is upon you to bring this Wing back to its pristine beauty and from the looks of it the task doesn't appear too difficult. fluffy: If you ever stop in Foley MN and you run across a " Dziuk " or a " Jacquemart " tell them one of their own is alive and well in Virginia.
If you need real gas go to www.pure-gas.org. and http://buyrealgas.com/
If you need a manual go to www.usedgoldwingparts.com
If you are close to a Honda Motorcycle dealer you can get the premixed coolant, oil filter and Honda oil.
You can also get factory service manuals through the dealer and yes you can get a GL-1100. Basically you have a 'Hybrid' GL-1000/1100.
