Let’s install the carburetor.

It’s still usable, but the intake manifold is also discontinued. It’s still functional, so that’s fine, but this Honda motorcycle will be challenging going forward.
I’ll just replace the O-rings.

I mixed clean parts with everything else and assembled one complete unit. I felt the disappointment of the aftermarket repair kit, but I used only the O-rings.

I’ll change the oil to Newtech.

Just because it has a ball joint doesn’t mean I can recommend using it at an angle. With this backstep configuration, it ends up this way, so there’s no helping it.

Depending on the position, there are spots where it makes contact.

To use the limited stroke smoothly without waste, 90 degrees is best.

The mounting position has minimal vertical travel, so there’s less stress.

The structure of the drum-type backstep is also troublesome. With four components from the drum arm to the pedal, it becomes like a puzzle and you can’t use the ideal stroke position.

In the end, I reduced the stroke as much as I could on my own. It took about an hour and a half of repeated attachment and detachment to find a good position, and we settled on this as the limit. Since I’m doing this on my own, it’s completely unrelated to the requested work, but I think it turned out well.
