Yoshimura ST-1 camshaft, fever mode activated! <\/h2>\n\n\n\n

It might seem like I’m changing these frequently, but actually it’s not that often.
Since I’m used to working on the 1200 series, things move along smoothly! <\/p>\n\n\n\n\n\n\n\n

This is what it looks like inside.
Since we did the oil-cooler maintenance the other day, it’s pretty much as expected\u2014nice and clean. <\/p>\n\n\n\n

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

What’s that poop-like stuff…?
It shows up occasionally, but is it oil components? Sludge buildup? <\/p>\n\n\n\n

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

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

I’ll replace the cam chain guide too.
It’s a good idea to GET it while it’s still available. <\/p>\n\n\n\n

If you’re planning an engine overhaul,
it’s good to pick up the tensioner side too, since you can’t replace it without splitting the case. <\/p>\n\n\n\n

Well, there’s nothing particularly wrong (*\u00b4\u03c9\uff40*) <\/p>\n\n\n\n

I soak a rag with engine conditioner and rub it with my fingers.
It’s pretty tedious, but it gets surprisingly clean. <\/p>\n\n\n\n

Even though cleaning doesn’t boost performance,
it’s definitely a plus. <\/p>\n\n\n\n

The dirt comes off very cleanly.
When I mount it directly, I wash it thoroughly on the cleaning stand. <\/p>\n\n\n\n

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

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

I’m using “ Wako’s Engine Conditioner <\/a><\/strong>“.
Honestly, any brand works fine. <\/p>\n\n\n\n

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

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

It’s a small joy when all the gaskets stick to the tensioner…
They peel off easily (*\u00b4\u03c9\uff40*) <\/p>\n\n\n\n

The cam assembly is complete! \u266a
Next is valve timing adjustment and the cam replacement is done.

That’s all for today\u2014putting it on hold for now! <\/p>\n\n\n\n
