This is another beautiful GSX-R1100M in great condition.
As well-preserved examples become rarer, it’s more about nurturing the one you have.
It’s got what looks like an RK carburettor on it for some reason, but there’s definitely a story there.
It was tough getting it off this time—I even gave my right wrist a mild sprain.
I was genuinely nervous, thinking it would never come loose. Now I’ll clamp it to the carburettor stand and go at it with the Makita, grinding away! Time to disassemble.
For some reason, the drain—or rather the MJ—has an easy-swap cap.
It’s got a nice coating of blowback gunk on it.
The butterfly side was still in pretty good shape.
It’s got an old-school power jet, but it’s blocked off so we’re removing it.
By the way, the hose is completely brittle.
There was a little rust in one spot, but nothing to worry about.
Took the four-barrel completely apart.
One spot got crushed to bits along with the hose. I’ll fix that up.
This was the first time I thought an NJ wouldn’t come out. The MJ spun along with it, and I thought I’d have to cut it, but by holding the anti-rotation pin and turning carefully, it finally came loose.
I’m not sure if it was over-tightened or seized, but either way it was stubborn.
The fuel passage seal was also at its limit.
That mystery intake manifold bolt was a pain to remove too—the neck is just too short.
Anyway, glad there was nothing wrong with it.
The recent issue of it leaking when hot—probably that.
I think it’s the fuel sensor seal. That said, the sensor itself looks pretty new.
It was loose, as it turned out. Applying oil stone would give us extra peace of mind.
Fluorine grease gives both sealing and lubrication, so I thought it might work well and gave it a try.
The engine side is capped for now and on hold.
I’ve polished two of them so far.
Maybe this is what they looked like thirty years ago?
To be continued.
