The GSX-R is now 30 years old. At that point, the clutch plates just can’t hold up anymore. Along with the inspection, we had various requests. <\/figcaption><\/figure>\n\n\n\n\n\n\n\n

This one is a steel plate. <\/figcaption><\/figure>\n\n\n\n

This one is a friction plate. <\/figcaption><\/figure>\n\n\n\n

What’s interesting is
peeling present = outer side
no peeling = inner side.

I was thinking in my head “this is how it comes apart,” fidgeting a bit. Then I thought, “Ah, I get it!” and moved on.

To all you GSX-R owners, we’re waiting for your FCC clutch replacements. <\/figcaption><\/figure>\n\n\n\n
\"\"
After inspection, here’s the FCC clutch kit.

People ask, “Why not OEM?” Well, I’m guessing, but I think OEM is made using older designs the same way. (Though they probably have some compatibility with friction materials and such.)

Again, just guessing, but I think FCC and similar brands use newer, better friction materials and processing in their product lineup\u2014meaning they engage smoothly and don’t slip as easily, or so I’d say. <\/figcaption><\/figure>\n\n\n\n
\"\"
People always ask, “Where did the debris go?” Well, I think it’s turned to mush and circulated throughout the whole engine by now.

We drained the oil, removed the filter, and checked the oil pan from above. Yep, nothing there. <\/figcaption><\/figure>\n\n\n\n
\"\"
The clutch hub wear is gentle\u2014reassuring. Suzuki builds them tough! <\/figcaption><\/figure>\n\n\n\n
\"\"
We replaced the center nut with the later crimped type. 140\u2013160 N\u00b7m is no joke.
I wonder why only the early GSF1200 has a looser spec? <\/figcaption><\/figure>\n\n\n\n

Hook it up, protect it, and go through the process. If it flies off, the frame goes “screeeee” and you’re on the express train to hell. <\/figcaption><\/figure>\n\n\n\n
\"\"
You can hook it on the pivot, but since it’s thin, make it as thick and solid as possible. <\/figcaption><\/figure>\n\n\n\n

When you replace the oil sight glass, it goes snap!

I’m thinking of bundling these together. <\/figcaption><\/figure>\n\n\n\n

A little trick for when the gasket won’t come off.
Be careful not to overdo it, but since gaskets are paper, they’re surprisingly weak to heat. (Be careful not to overdo it!)

A gentle flame should peel it right off. <\/figcaption><\/figure>\n\n\n\n

We fabricated a muffler bracket. The fairing was surprisingly close.
It’s co-bolted with the fairing boss, so we didn’t drill. 20\u03c6 7N01 aluminum. <\/figcaption><\/figure>\n\n\n\n

We painted it black with gun coat and it’s done. <\/figcaption><\/figure>\n\n\n\n

From a certain acceleration point on the straight, it was bucking. A large filter was installed, so we removed it for now.

Fuel filter air ingestion is nothing to sneeze at, so watch out. Even when reinstalling, direction matters. Bikes can be tricky that way. <\/figcaption><\/figure>\n\n\n\n
\"\"
Hose replacement became necessary, so we removed the carburetor. <\/figcaption><\/figure>\n\n\n\n
\"\"
The hose is Mikuni two-layer. This gray fuel hose is especially good.
It’s soft yet doesn’t kink easily. (Though it can kink if pushed.) The layout and removal feel really nice.

There are stiff fiber-reinforced hoses because people worry about kinking, but they’re pretty awkward to work with. You just need to route things smoothly. What matters is:
\u2022 Tank removal and installation are easy with minimal, relaxed routing
\u2022 Hose that doesn’t kink even when U-turned
\u2022 Hose that doesn’t collapse even through tight spots
\u2022 Gentle aging and resistant to cracking


In all respects, setting things up so nothing becomes a hassle later is what’s kind to everyone.

That wraps up today’s work.
