Did you know that tonkatsu tastes sweet when eaten with rock salt?
Wow! I didn’t know that….

I learned something new today, so all good (*\u00b4\u03c9`*)!

Now let me continue with the work~<\/p>\n\n\n\n

Since Okabo wasn’t around,
I prepared it in advance. <\/p>\n\n\n\n

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

The inverted fork was
measured vertically
due to the bottom case configuration.

Everything checked out perfectly. <\/p>\n\n\n\n

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

I sealed it with reliable fluorine grease
and assembled it.

It’s great when things stay in good condition for a long time. <\/p>\n\n\n\n

<\/div>\n\n\n\n

Manuals from this in-between era are hard to come by.
*Especially for domestic mid-displacement bikes.

All I need are the numbers
When I borrow from customers,
saving images is perfect. <\/p>\n\n\n\n

Makita VP180D <\/strong> vacuum pump to <\/a>
properly bleed out the air.

What’s great about it is
first, it’s cordless,
and it’s compact with plenty of power

Once you learn air bleeding with vacuum,
your “peace of mind” increases,
and the work becomes “faster”.

Definitely! This year
try going cordless. <\/p>\n\n\n\n

<\/div>\n\n\n\n


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

I’m not great with this Honda design

Probably,
it was designed to make
spring replacement easier?

Still, people who come up with things like this are amazing. <\/p>\n\n\n\n

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

Just to be safe,
I measured the
fork spring rate roughly.

Fork springs
are long,
and if you’re not careful,
they’ll “fly off”

I use a
simple attachment for measurement. <\/p>\n\n\n\n

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

The axle shaft runout is also
no problem.

There was a request to reduce preload a bit more,
but I declined this time.

There were mysterious aspects
to the fork itself,

so I decided it was better
to reset the condition first
and then adjust from there.

Next is a test ride to complete it~(*\u00b4\u03c9`*)<\/p>\n\n\n\n
