After owning one, I realized…
the Inazuma 1200 has this image of being way too toned down. <\/span><\/strong>But actually?

it’s a bike that can unleash hidden power. <\/span><\/strong> *Though it does cost money…

So, with much anticipation, I’m installing the Yoshimura ST-1 Cam. <\/strong><\/p>\n\n\n\t\t

Boosting the potential of the oil-cooled 1200 with the long-awaited Yoshimura cam! <\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Depending on stock availability, this is a part that’s hard to get your hands on.
We’ve got only 1 unit left in stock (already reserved) = out of stock. <\/span><\/strong>

Since most people won’t buy it twice… we’re going to stop stocking it and arrange it as needed going forward.

I’m not sure if it’ll become a custom ground cam in the future, but
“the current oil-cooled Yoshimura cam pricing is divine!” <\/span><\/strong> *It hasn’t changed much from decades ago. <\/p>\n\n\n\n

If you think about it, now’s the time! Grabbing one as a backup stock is also a good idea. <\/span><\/strong><\/p>\n\n\n\t\t

Rocker arms are like a married couple\u2014it’s best to replace them together. <\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

As a Repro proposal, <\/span><\/strong>we’d suggest
“Performance Parts” <\/strong>like “RK-type Lightweight Rocker Arms” <\/span><\/strong>
\u2014they seem to have broad appeal for both race users and street users (*\u00b4\u03c9\uff40*).

But setting aside such dreams, we’ll be using the stock rocker arms. <\/p>\n\n\n\n

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

We use both aluminum and copper for the oil lines depending on the application. <\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

For areas where we want a tight seal and no leaks, we use copper.
This is just my preference, but “I don’t use the stock aluminum for this oil line section.” <\/strong>That’s how I do it.

It’s just an impression, but aluminum seems to get tired and weep a bit over time.
If you seal it up tight with copper, it should stay clean all the time. <\/p>\n\n\n\n

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

Since it’s Saturday, <\/h2>\n\n\n\n

Things are progressing smoothly.
We’ve had a few visitors, but doing cam replacement work two days in a row has made us pretty practiced at it. <\/strong><\/p>\n\n\n\n

We quickly adjusted the valve timing and got the cover back on.
Now we’ll give it a good crank and fire up the engine! <\/p>\n\n\n\n
