Mileage: 65,000 kilometers—quite a bit of riding there…
Now, regardless of mileage, the internals are in great shape ★
It’s in remarkably clean condition, and the cam shows no signs of seizing.
It seems that when you ride consistently, cam seizing is less likely to occur.
The quality of engine oil doesn’t seem to have that much impact (though whether ultra-cheap oil is okay is unclear),
and it’s not about frequent valve adjustments either.
What matters is that during each ride, you establish stable oil pressure and keep the oil circulating well, so that before the head oil drains away, you ride again—
that’s what I think is best.
So you might think, “Well, if we’re just looking at valves and such, we don’t need oil-cooled maintenance at all!”
But we don’t adjust things just because they’re broken;
it’s better to ride in a smooth, well-running state,
so that’s why we do the adjustment ★
Engine dampers wear down and cause fine vibrations.
Generator dampers wear down and cause rattling at idle.
When valve timing goes off, it gets noisy, and I want to visually inspect the rocker arm wear to understand where the noise is coming from—
that’s the point ★
We also check and adjust cam chain slack, which stabilizes valve timing that might otherwise shift front to back.
Since cam chains don’t stretch uniformly around their entire length, we visually inspect and check the slack before adjusting ★
Once we adjust, synchronize the carburetors, and tune the idle, things should improve a bit—
But anyway, let me set that aside…
The engine oil has been changed regularly, so the internals are nice and clean.
There’s some wear from the mileage, but it’s still got plenty of life left.
The steering was heavy, so I adjusted it!
I also adjusted the brake pedal position on my own!
Once you start, there’s no end to it, so we’re calling it done ★
Shiny!
