Randakks cycle is your new best friend. Check his site, it and naked goldwing is a wealth of info for newbies to the GL1000 and 1100. He is on vacation until April though so you can;t order any parts at the momment. His Tech tips section is gold. Paul Dutra from TO did a GL with the tank removed and one strapped to the fake tank area, check it out. Also another NGW club member did one with a mono shock conversion that is crazy cool. Don't let Swivel scare you. If you know what you are doing anything can be done. Would I? No cause I have never held a welder, but if I could weld, I would do it.
Cheers,
