Photos make it look like it goes by in a flash… the tedious work takes the most time and doesn’t even show up in pictures.
This part is off-topic stuff. It’s more like, should I put a GSX1100E tank on the GS1000?
I made the parts pretty casually. I couldn’t do it this way on a real job.
This one I cut and bent too…
Welded with a patch-on rib.
This one I cut and welded too, and now it can go on the GS1000S frame.
The tunnel was wide, which helped a lot.
GSX1100E—I cut off the normal mounting ears. When I TIG welded it, there seemed to be paint inside, so it was sputtering and wouldn’t stick, so I ran solder through it.
Not touching it and getting hurt is good manners.
Then the seat wouldn’t tighten… which was expected. Since the basic idea is no modifications to the main body and being able to revert it, I made a seat offset plate and a fuel sensor blind.
Following the common wisdom that “black hides the rough spots and looks good,” I painted it black to cover it up.
With a flange lock, I was short one tooth—that was unexpected… and the seat shifted.
It’s held tight and looks good.
It overlaps the tail cowl a bit, but that’s okay.
Thanks to the loose tolerances of that era’s bikes.
I’ll just buy a repro tail cowl and ride with this tank for a while.
All that’s left is the P44MM petcock and cap, and we’re done!
