Wow! A supplementary manual for the 750/1000/1100 like this…
I ended up buying it the other day—DHL being delivered by Sagawa? A mysterious delivery.
The content feels both thin and dense, and I secretly think it might be a rare Suzuki collector’s item.
The 750 import has clip-on bars, huh? I didn’t know that.
I got sidetracked. Let me get back on track.

The corrosion on both top and bottom is pretty spectacular.
I cleaned it up lightly.

That’s how it is. (Top image only) *I’m doing the bottom too.

I also cleaned up the parts I’ll be reusing.

It still works, but the overall condition of the carburetor is poor.
I can feel the harshness and age of the BS carb. The domestic SR has also been around for quite a while.

I have a feeling the float valve is probably shot, but I finished it up anyway.
Metal ones have low reliability.

It won’t pass at all… The air jet passage is completely clogged and hopeless… How do you clear it?
Keep away from open flames and make sure it’s completely dry or it’s dangerous—don’t try this carelessly.
There are also seals and such, so if you’re not careful you’ll get hurt.
Overdoing it is absolutely no good. A light heat will melt the solidified gasoline and the passage clears right up.
Using carburetor cleaner on a clogged carb will open it up somewhat, but when you want to do it properly and quickly, this is the best way.
I’m recommending it and not recommending it at the same time… It’s complicated.


The starter circuit passage is similarly completely clogged and hopeless. Once gasoline rots and clogs, no amount of pressure will clear it.
A good quick heat—salmon-colored?—soft and fragrant ♪ It cleared right up.

Listening to past interviews with Suzuki chairman Osamu Suzuki… assembling the carb today.
I’m not taking the four-stack apart this time. Finally reached the actual fuel level after cleaning.


Having a service manual when you disassemble a carburetor gives you tremendous peace of mind.
With a used bike you never know what you’ll find. They’re fun to read too, so it’s good to have them on hand.


When I was checking the #1 fuel level.
#2 started dripping slowly… and it won’t stop no matter what I do.
This definitely calls for a needle valve replacement… Honestly, the price scares me these days.
BST was already at 6,000 yen per unit… I’ll look up the price.
The holiday season is starting, so with parts availability and all, this is on hold for now (‘ω’)ノ
