A BST enthusiast has requested carburettor overhaul.
They don’t want to disassemble the four-carb setup themselves, the fuel seals need replacing soon, and they want the actual fuel level adjusted.
That’s very wise indeed (^^♪
It could’ve been done quickly, but timing’s been off lately (*’ω’*)
Work is progressing, though we’re only partway through.

Now let’s disassemble the carburettor.
I always think whoever invented the carburettor stand was a genius.
The fuel passage location and diameter are pretty similar across most carburetors…
Reading old biker magazines, you’d find some master craftsman having an “aha!” moment—and that was the carburettor stand.




No rust and in excellent condition ★ Since they maintain it regularly themselves, the condition is outstanding!


The float is still in great shape… thinking back to that carb from the other day, it was pretty bad.


It’s just rubber after all. You really want to replace it after ten years.
If you keep using the four-carb setup for 20-some years without taking it apart, it’ll hit you suddenly… gradually.

I was torn on it, but I went ahead and coated it.
Working in a way you won’t regret gives peace of mind.

When I think I’ve messed up an order, I usually have stock on hand, so we’re safe (*’ω’*)
Turns out I didn’t mess up after all φ(..)Memo memo

The BST starter valve is cheap and nice
Suzuki’s always been like that, and it gets me nostalgic ( ;∀;)


Got some top-tier block, slide valve, and diaphragm pieces… that kind of vibe. Recent sellers are pretty hardcore, and so are the buyers, I guess.


The hole diameter is… large. It might be enlarged or from a 1100K or something (vague memory)
I’ll assemble it with stock specs.

Finished it up light

Just the bottom half left (^^♪ I’ll get to it tomorrow.
Now that the rainy season’s over, inquiries are piling up and I’m exhausted (‘;’)
