You'll learn a lot from the GTS guys at the rally. The 10th Anniversary Rally was great! Just don't listen to ANYthing Shawn P. says...

I considered selling it awhile back, but I'm glad it didn't sell.
You CAN still get the mounting kit for it, and any Givi bag will mount.
Get on the GTS1000 maillist. There's a LOT of info there, and in the Archives.
