The carburetor came out cleaner than expected, I’m impressed (*´ω`*)
The carburetor is surprisingly dirty. *Because it’s old
Looking closely, there are cracks and weathering is pretty severe.
Work that properly matches its actual age is necessary ( ;∀;)

Ordered a 3φ shaft-mounted brush (SUS 0.3)
When polishing the aluminum parts of the generator during oil-cooling maintenance, it becomes shiny ☆
I remembered that.
I went with Trusco for now (*´ω`*)
*TRUSCO Cup-type Brush Stainless Steel Wire 0.1 x Outer Diameter Φ13 x Shaft Φ3 133C-4

It goes at it aggressively like this.
This small cup-type brush is really quite good.


While not quite wet blasting, it should bring things back to life quite a bit.
For parallel 4-cylinder bikes, you could even polish with just cylinders 1-4 mounted?
If you did it for 30 minutes, it would probably get terrifyingly shiny.

I found something interesting. *Bit 2.35φ
Wow, such an item exists in cordless form – that’s amazing!
If you don’t use it for long periods, something like this is sufficient.
As a first rotary tool, the price is reasonable too.
The uses are endless!
It’s nice to have such a wonderful item.



Leave the tired diaphragm untouched!


It becomes incredibly clean. . . . Please make use of it (´ー`)


It’s an unnumbered needle or I have a feeling it’s Dynojet-like based on the hole.
The air cleaner box is also honeycomb, so that’s definitely it.


I’ve ordered replaceable parts, so I think we’re good going forward.
