Well, they sure made a lot of them back then~
250\/400\/750\/1000\/1100
I just got to thinking.

Actually, this idea…
That’s right! The Katana as-is in 250\/400
I wish the new Katana had been like this

Well, that one is what it is<\/p>\n\n\n\n\n\n\n\n

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

The GSX250S ignition system is full transistor
not CDI ignition
Therefore
that box is an igniter, you see.<\/p>\n\n\n

\n

The story goes back about a year<\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n


The starting was really bad
spark is flying, but compression is low
Therefore
“Spare Katana and engine swap strategy”
was supposed to be?


When two bikes came in together<\/p>\n\n\n

\n

Could it be?
An igniter issue?<\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n

Swap it in and… one shot.
Huh… silence(;\u30fb\u2200\u30fb)<\/p>\n\n\n\n

Now, let’s get back on track
The spark plug looks like this currently.
It’s pretty much fine<\/p>\n\n\n\n

Everyone’s favorite
GU-53C compression tester<\/a>
Let’s check the cold compression.<\/p>\n\n\n\n

I don’t have this manual
but it looks fine.
Let me check unit #1 again
and make a judgment<\/p>\n\n\n\n

It’s quite a slow leak.<\/p>\n\n\n\n

For now, let me clean it up
and JBWELD it…<\/a><\/p>\n\n\n

Whoa, it’s collapsing!<\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n

Looking with an endoscope…
Coating applied over rust without removing it?
It probably stopped it to some extent

but under the coating
corrosion progressed
<\/p>\n\n\n\n

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

Gasoline is pooling under the coating and keeps coming out

After letting it settle for a few days
I’ll fill it with JBWELD.<\/a>
<\/p>\n\n\n

\n

For now
I think it’ll hold.<\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\t\t
