The GSF1200 is still going strong! Inspection, crowdfunding 70,000 yen maintenance, oil changes, and more

This GSF1200 has been with me for a very long time.
There were actually many areas I wanted to check due to age-related deterioration and fine wiring and insulation issues.

It’s hard to tackle these things without time and peace of mind.
I think this inspection has really cleaned things up nicely (*´ω｀*)

Small improvements are surprisingly tedious to make.

It’s surprisingly common to have things sticking out—like a detective with a pure heart!
I’ll also remove unnecessary lock washers and cut the bolts shorter.
Since there’s a possibility of wiring getting cut, it’s important to keep things as clean as possible.

Multi-taps and cut wires kept popping up, so it was really good to check everything this time.

I’ve also set up two optional power sources properly with 110-series connectors.

By the way, if the headlight lens requires brute force to push in, that’s abnormal.
If that’s the case, you need to properly bundle and organize the inside, or you’ll run into electrical problems.

Normally, the lens should fit in easily with the screw holes completely visible, as shown in the image.

Now I’ll repair the insulation and deteriorated parts around here.

This is incredibly nostalgic… the barrel cover.
I’m so happy it’s still being used. I’ve had everything wet blasted and restored.

I’ve also installed covers for the Öhlins reservoir tank and hydraulic preload.
The materials have gotten really good lately, so it’s a huge help.

I’ve also covered the steering harness insulation that had torn.
The GSF has already been around for nearly 30 years. It’s older than I thought.

I’ve also installed a new hose to the catch tank.
I’ve also installed the serial number on the plug cord this time.

It was great to have the opportunity to redo these small details.

Now I’ll move on to maintenance smoothly.

I’ve cleaned the carburetor and balanced the synchronization.
It’s a small thing, but it makes a subtle difference in how the bike runs.

Since I haven’t been able to do these things before, the work feels really fulfilling.

The spark plug is JR8B. Since Watanabe is installed, I’ll fit the NT4245.
This terminal cap is also a consumable, so replacing it at the same time is effective.
And make sure to open the gap too.

Check the fuse box occasionally.
While it doesn’t have a huge effect, the fact that you’ve checked it should give you peace of mind.
Plus, fuses don’t cost much, so just replacing them occasionally will freshen things up.

Finally, I replaced the front and rear brake fluid and clutch fluid, and we’re done.
There are many other things I haven’t written about, but I think this time we’ve achieved a really solid finish.
