GSXR750 GR71-series VM carburetor
probably? I’d like this to be the last time I overhaul one in my life…
It’s a category I’m not great with, second only to the VF1000R carburetor ( *´艸｀)
I’ll take it apart piece by piece.
By the way, there’s a check ball in this accelerator pump passage. If it wears out, it can cause strange leaks, so be careful.
It’s so bad that if parts are available, I’ll replace it.
The float valve is also shot ( ﾟДﾟ)
O-rings and seals for spots like this aren’t available.
Not all parts in the parts list are supplied, so I’ll cover it with substitutes.
To pull the rod out, you have to remove this pin or the four-barrel won’t come apart…
Please pull it out with love and friendship, not by hitting it.
This era has a lot of tedious steps.
I want to complain that there must have been a better way to do this mounting (; ･`д･´)
Be careful in this area….
There are two places with a spring and steel ball that create the click feel—that crisp sensation—when you pull the choke. Make sure you don’t lose them.
The shaft seal uses something like felt, but there’s no replacement for that either.
Is it basically saying you’re going to overhaul it anyway?
That’s it—I’ve got the four-barrel disassembled for now.
It’s been a while since I’ve seen a carburetor in this bad condition.
Unless you have a strong attachment to it, I wouldn’t recommend overhauling this type.
Don’t think that just ordering parts from the parts list, cleaning the carburetor, and reassembling it will give you performance. You might be very wrong.
This is how I finished it.
There’s no end to it, so I wrapped it up in bamboo spec.
The corrosion was surprisingly deep, and removing it is a race against time…
Still, it’s come back to life more than well enough ( *´艸｀)
The float chamber is clean too (*´ω｀)
I gave the top cover and mount bracket a guncoat touch-up too.
For now, getting it to four barrels is a relief (*^-^*)
I’m waiting on some parts for now~
