It’s still okay. It’s still okay. You know that commercial where they pour water into a cup? <\/h2>\n\n\n\n

<\/p>\n\n\n\n

I replaced the brake master and remade the brake hose the other day, running smooth and smooth.
But then…
Next thing I know, the fork is leaking…

Since the inner tube is shot, I’ll replace it at the same time. <\/p>\n\n\n\n\n\n\n\n

The fairing is a bit tricky to remove, so I’m lifting it up. (Double insurance?) <\/p>\n\n\n\n

I have a front stand but basically don’t use it…
Isn’t a front stand difficult to work with? <\/p>\n\n\n\n

Now… I’ll remove the fork and proceed with the work.
*It’s snowing outside… somewhat concerning. <\/p>\n\n\n\n

By the way, apparently it’s never been replaced in 70,000 kilometers.
Hmm, thinking about it that way, it’s pretty clean, isn’t it? <\/p>\n\n\n\n

If you use an older, lower-quality fork, you’d understand…
There’s no “metal” feel.
It’s purely a moving condition of fork oil degradation.
21st-century forks are amazing!

*Apologies for the somewhat unclear meaning. <\/p>\n\n\n\n

And the number of parts is incredibly small. (*’\u03c9’*)Whee <\/p>\n\n\n\n

That’s nice. I think simpler is better in everything. <\/p>\n\n\n\n

I’ve darkened the color in editing to make it clearer.

The inner tube with worn plating.
“Even when measuring dimensions, surprisingly little is actually worn away” <\/strong>is the thing.

“The inner tube of an inverted fork always contacts the same spot” <\/strong>
The front should be particularly tight.
Even with an oil seal, it gradually scrapes away the plating surface.

By the way, “you can rotate the inner tube on a conventional fork” <\/strong>so “you can change the contact point 360 degrees to make it last longer” <\/strong>which has significant advantages. <\/p>\n\n\n\n

Reliable genuine new parts. I think there’s almost no chance of unexpected trouble (*’\u03c9’*) <\/p>\n\n\n\n

<\/p>\n\n\n\n

Cylinder tightening is important.

Please use new bolts if possible. I think genuine steel is more reliable. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Recently, if oil seals are under 1,500 yen each, I go with genuine.

SKF?
SKF is a bit pricey, but with this “fluorine grease” seal, fork oil leaks have dramatically decreased in my experience.
By sealing with fluorine, “smooth, no leaks, affordable” – that’s probably how it works. <\/p>\n\n\n\n

The fork is now assembled…
I’ll vacuum it with a Makita and then adjust the oil level.

Vacuum isn’t really necessary, “to be more certain” <\/strong>if you want to think so, vacuuming is the safest bet. <\/p>\n\n\n\n

I also replaced the bolts with steel (trivalent black) of the required strength grade. <\/p>\n\n\n\n
