It has an in-tank mounted fuel pump.That seat issue is similar to FZR400 race bikes which all have the rear subframe surgically shortened to fit inside a race tail. Our FZR wasn't raced AFAIK but some PO had chopped the back end off so I had to construct a new subframe to support the tail lamp properly.
BTW, does that bike have a small cylindrical fuel pump? The 400 fizzer does and the point erode and the electrical components corrode from moisture in the breather duct. I had to replace the same pump on my late brother's Honda Hawk V twin and the spare for an FZR1000 I had lying around also turned out to have rusty and pitted points.
Unfortunately, it looks like we have some fitment issues here as well.
I'm assuming that this fairing was designed for race use, as the front mount is still several inches away from the fairing but the top is run up against the gauges.
Also, not pictured, is the locations for the frame sliders are now blocked.
Additionally, the headlight assembly mounts to the fairing (not the frame) and there are no cutouts for the bolt holes (which may need to be recessed).
Looks like I might need to consider some different options before I end up going too far down this rabbit hole.
