Ya, I picked up a 2001 R6 tank to use the Fuel Level Sender out of to wire up to my Acewell. That part will be super simple.
Since I have the tank I started looking into taking the cap section. Measured the cap section on the R6. The counter sunk portion is about 3/4" deep. And then the filler part has a lip down in the tank. The total height is just over 2 inches. If I measure the 550 tank I only have about an inch and a half from the top of the tank to the hump about 2 inches back from the front of the tank. Not really any room to lower then hump obviously so I starting think I could take the taper of my seat and apply it to the tank. I figure I only need 1/2" - 1" additional height to make this work.
I thought about offsetting it and haven't completely disregarded it. Just really like the look with it on center.
I also threw it up on the frame late last night and it didn't look to bad. Also hopped on the interwebs and found this:

I know I don't need to "bubble" it as much but I like the concept.
I know this is going to be expensive but I haven't seen anyone else do this just yet so I kind of like the idea of do something unique, ya know?
