We took our time with the delivery schedule, and it’s already been nearly five months—I’m amazed myself.
The flow goes: disassemble → takes up space and risk losing track of parts → prioritize inspection and maintenance → things keep getting delayed.

【To everyone】Work involving custom fabrication may have longer lead times depending on shop availability.
I always think about this, but custom work and fabrication jobs are definitely faster and finish cleaner when you ask a custom shop or fabrication specialist to handle them.
Disc replacement means replacing the mounting bolts too. The tightness feel when there’s plenty of Loctite is hard to judge.
I dropped it and did the work at a shallow depth with liquid. (So it’s easy to remove if it breaks.)
We’ll replace the wheel bearings too.
It won’t wear down, but I’m marking it so nobody does any unauthorized modifications. If it gets peeled off, we’re out of luck, so it’s a bit iffy.


Left cover. Since no oil is leaking, we’ll use it if we can.
If it cracks lengthwise, surfacing is a pain and takes time, so we decided to replace it.
The generator wiring is already brittle and I’m worried about it. For now, there’s no end to it, so we’ll leave it as is.
We connected and extended it.
Wrapping it with mesh and heat-shrinking it looks a bit cleaner and works well.
Connectors are basically better. They seat firmly and lock! This reduces the chance of forgetting to insert them or them falling out.
With just spade terminals,
• insertion can be sloppy (since you just hand-insert and call it done) *using a thin flathead screwdriver to seat them properly gives peace of mind.
• they loosen (= easy to come off, and contact becomes poor).
• labor increases. With connectors it’s one step, but with just spade terminals it’s three.

Taking a little extra time on one step improves both peace of mind and work efficiency going forward. Small things add up—slow and steady wins the race.
Just touching it and the insulation crumbles and breaks. Since there’s no end to it, we didn’t dig deeper and just wrapped it for repair. (We have a harness replacement planned.)
A common one—grounding. Why add so many battery grounds? We forcibly removed them.
By the way, the ground running through the main harness is just one wire, about 1.5 or 2 square millimeters, in the blurry foreground of the image.
If you drop it from various points on the harness, maybe there’s some effect? I think so, but…
I’m not sure. Since it’s long, we’ll cut it out.
It’s more important to make sure the ground is solid before adding parts. Getting the basics right first gives you peace of mind.
Kijima and Daytona are trending lately.
They have amazing products coming out constantly. Kijima’s IC turn signal relay
With this, you don’t Motogadget anymore.
It’s basically for two-pole, so think about it if you’re using it for three-pole. (It’s not that bad, but…)
The label maker tape is so we don’t forget what things are in the future.
Working on wiring, I think…
“Are you deliberately making this complicated?” That’s what I think. Even though the other end is a different color, everything is spade terminal connections.
Markings done with masking tape and marker…

The labor is the same whether you use connectors or not, I think.
I’m cutting corners on wiring. We made everything connectors. *If the shapes are the same, marking them is safer. And if you set the polarity so it doesn’t matter if you plug it in wrong, that’s even better.
