Shot in HDR for a natural finish. There’s quite a strong smell to it.
Then… something caught my eye… oh no—a major crack.
There’s no front sprocket available to convert the GPZ750F to 520, so we have to adapt a Sunstar one—which means some modification is necessary.
But since that wasn’t going to work, we’re going a different route.
Either reduce the front or increase the rear. Since we have to increase the rear, we’ll make a shim. We’ll punch it out—
—and there we have it. With the right tools, you get a clean, quick finish.
This time the rear is RK as requested, steel with lightening holes.
Bend it perfectly in two spots and you’re totally safe.
Oops! I didn’t realize until too late… I threaded the chain before fixing the crack…
Well, no point getting discouraged! It came out clean.
Various sketchy spots, but… we’ll seal them lightly and move on.
There’s squeaking here and there, so we remove, tap, spray, spray again, and oil—that’s the process.
That exhaust coating is pretty stubborn, but this time we’ll keep it light.
We’ll touch up all the parts and put it back together.
The inside can’t be welded without dropping the engine, so we’ll just prep it lightly and weld it for now.
That’s how we covered it.
*The shaft looks misaligned, but it’s fine! It’s smooth.
The bike leans hard on the side stand = more stress on the frame = it breaks. That’s the chain of events.
Turns out the bolt was coming loose.
The GPZ doesn’t have a lock nut? That’s a bit of a design flaw.
For now we’ll just raise it 10 mm. We’ll cut the sole—that’s the process.
That’s how we welded it. I rushed a bit, so the heat might be a little much—I might get scolded for it.
For now, we’re done.
